Flashing An Align Trex 150 DFC With BLHELI

Flashing An Align Trex 150 DFC With BLHELI

What is BLHELI?  It is free third party software that that replaces your helicopter’s stock software so you can reprogram many rc helicopters in order to upgrade main and tail motors.  On top of that you can ticker with almost all of the settings for your helicopters motors.  You can change how they start up, how fast they spin, etc.  Without BLHELI a helicopter’s stock software maybe able to spin up an upgraded motor, but the stock software will only be able treat any motor you put in it as the stock motor.  With BLHELI, a helicopter is capable of pretty much any motor that you can fit into your heli’s frame.  If you end up putting in  a motor that is more powerful than you thought, you can use BLHELI to lower the settings and make the motor act like a stock motor and will allow you to step up the power at your own pace.  That’s it in a nutshell and it is often upgraded to support newer models.

First thing, flashing an Align Trex 150 DFC with BLHELI is not a completely small task, or is flashing any heli.  It takes planning and patience.  There is a lot of information here as well as on the internet.  Start your research here, then check out Heli Freak for more.  I am not going to add click links to this page to split it up like I normally do.  I apologize to those of you that are experienced and are using this page as a quick reference.  I am here for the newbies and if you are new to BLHELI flashing you should read this page in it’s entirety before proceeding.  This is all fairly easy but if you are not cautious you can ruin your heli, so take your time.  There are many ways to do this.  I am teaching you the way that I have learned it and if something is not broken, “why fix it?”  I may try the other methods, but for now this works.  Read it and take your time.  DO NOT RUSH INTO THIS!

I love the Align Trex 150 DFC and was going to eventually flash mine with BLHELI.  Well, I’ve done it and I have to say that having BLHELI on this heli is an awesome upgrade to this already awesome helicopter.  It has been a while since I have flashed a rc helicopter and did have a couple of problems but it turned out to be human error on my part.  I had to refresh my memory on the process and learn all of the new tools available.  It turned into a week long process, but I hope to make it easy to complete for you (about an hour or two).  This was a seriously easy process and I had so much fun doing the first one that I flashed my second Trex 150 DFC too.  If you are hesitant or wondering if you can do it, I assure you that flashing BLHELI on your Trex 150 DFC is fairly quick and easy to do.  I am going to walk through everything you need and the process to include the stock motors, the two cell HP06 V2, and HP08 motors.  I will share my settings so far that are based on the settings that you can find at Astroid Designs.  It looks like Dylan from Astroid Designs is using an HP10 motor, so I modified his settings a little.  However, I am using the same tail motor settings on both of my setups as Dylan.  Most of the pro’s out there already know how to do this.  I am breaking it down for all of the new comers.

What is BLHELI?  BLHELI is software that replaces the stock software on your Align Trex 150 DFC MRS controller and that gives you a lot more control over your helicopter’s motors.  Sure, an HP06 and HP08 would work with the stock software but BLHELI is essential in order to open up all of the possible motors to their full potential.  There is quite a difference even with the stock motors.  The good thing about the Trex 150 DFC is that you do not need an external ESC.  You just solder on some connectors to hook up to a flashing tool in order to connect your MRS to your computer.  I’ve flashed most of my helicopters such as my Blade mCP X, Nano CP X, and 130X.  You can read about them on their pages and see some of the other tools that we used to flash our helicopters with.  Now it is much easier and I am going to show you how step by step.  Please don’t use just my walk through there are a few ways to do this and a lot of information out there on the process (helifreak, astroiddesigns, gitHUB, and google to name a few).  Let’s get started!

WARNING:  Flashing your Align Trex 150 DFC with BLHELI will void the warranty on your MRS controller.  Additionally, you will not be able to return the software back to the stock Align software, so continue with caution and I am not liable for any damage you may cause on your helicopter.  My process is not the only way to flash BL HELI, but is the process that has worked for me.  Please read through the whole tutorial before you decide to move forward.  As always do your research to find the other ways that BL HELI is flashed onto rc helicopters to ensure that you are using the technique that works best for you.

BLHELI – Finding The Software and Downloading

Current BLHELI software as of 13 December 2014

BLHeliSuiteBeta12200

 

1.  You will need to download the software from here.  This is the latest version of the date of this post and all of the hex files for all supported ESC’s that you will need are included.  Click on the file shown and download it.  Ensure that you know where you are downloading it to your computer.  It is self running software, so you will not have to install the software.

2.  Once the software is downloaded find where the zip file is located on your computer and extract the files.  When the files are extracted look for the file that I have indicated below.  That is the actual BLHELI self running software.  What that means is that the software does not actually install on your computer.  It runs only from the files that are located in the zip file.  It will not show up in your Start Menu or Control Panel.  You can even just run it from a thumb drive if you prefer.  Remember where it is for later or go ahead and copy it to your desktop.  The icon below is all you need to click to open up BL HELI.

UPDATE 12 Dec 2014:  Some time has passed since I started this page.  As stated in my flashing section I had to format my hard drive on my laptop after downloading the BLHELI software.  My laptop got bombarded by malware.  I am pretty computer savy, but even I could not remove it all without formatting my hard drive.  I love and respect the awesome guys that created BLHELI and this is not their fault.  They created free software for us and we should not expect them to pay in order to give it to us for free.  The issue is the site that is being used.  I intend to find a way to help them give this essential software to us safely on this site if I can.  I have to try out a few things, but in the mean time, here is what you need to look out for when downloading the software in order to protect your computer.  I am going to walk you through how I download it, I am not sure if there are any other places to get it.  This way is the safest way, since I trust the sources completely.

1.  Go to this Heli Freak page and you will have the link.  Click the link and you will be brought to the following page.

If you download it any other way you are in risk.  I got to where I was the both times I messed up my laptop through Google.  I should know better, but even I get in a hurry.  This is something that I do on my free time and have yet to make a profit from this site.  I want you to be safe and the last time I realized there must be some jerk out there trying to redirect you in hopes to get this software.  If any other windows open up, ignore them.  You will see exactly what I have shown  you.

The Tools That You Will Need To Flash BLHELI

Now that you have the software, you will need to buy a tool stick to actually do the flashing along with the appropriate connectors.  If you look at my Blade m CP X BL page you will see a different option for a tool stick.  Although that tool stick works well, I decided to try the newer more popular tool stick.  There are a few online places to purchase this tool stick.  Below is a couple of your choices.

1.  Astroid Designs ($16.00)
2.  Hobby King ($9.95)

With the tool stick you will need additional servo connectors in order to connect everything together in the end.  I have found two places to get them in bulk although the connectors are slightly different.

1.  Astroid Designs ($0.70 – 1 Pair)

Take note that these connectors are labeled backwards on the Hobby King site.  I labeled the links below as the Hobby King site has them, but the female is actual the male connector and the male connector is actually the female connector.  I wanted to make this clear in order to eliminate confusion throughout my walkthroughs.  Remember that a male connector inserts into a female connector (no pun intended).  Just to be even more clear, the tool stick cable in the picture above has a male connector on both ends.
2.  Hobby King (Female Connector)($1.28 – 5 Pieces)
3.  Hobby King (Male Connector)($1.28 – 5 Pieces)

NOTE:

a.  The connectors from Astroid Designs are a different color, than the connectors from Hobby King.  I am using the connectors from Astroid Designs, but will point out what you need to know if you are using the connectors from Hobby King.  The connectors from Hobby King are also a bit more fragile during the soldering process.  The insulation around the wires melts really fast (it melts as the heat travels through the wiring), so you will need to be careful with the temperature of your soldering iron and you will need to be fast with soldering your connections with the Hobby King connectors.

b.  Connectors from both places are interchangeable and can be connected with each other as shown below.  Hobby King connectors on the left and Astroid Designs connectors on the right (the black, red, white).

1.  I changed the connector on my tool stick, because of the room available in the MRS I wanted the male connector on my heli and the female connector on the tool stick.  Also, the male connectors are lighter than the female connectors.

2.  I know that not everyone has soldering skills and would prefer an alternative to soldering direction to their tool stick.  In this case you can get away with just modifying the included cable.  The following walkthrough will show you how to do it.  Just so you know, I have two tool sticks.  Above is a back up that I decided to solder directly to the board for demonstration.  Below is the tool stick that I have actually been using to flash BLHELI on my heli’s.  It works just as good as soldering directly to the board.  Let us get started.  Disconnect the cable from the tool stick and put your tool stick to the side away from your soldering area.

3.  Changing the connector is very easy.  Just snip off the end and solder on your new connector.  The cable is long, so I made sure to leave enough on the end that I clipped off incase I decide to use it for something else later.

5.  The connectors used for this are actual servo connectors.  Again there are a few places to get them in bulk.  Below are a couple of options.

1.  Astroid Designs ($0.70 each)
2.  Hobby King male connectors ($1.28 for 5)
3.  Hobby King female connectors ($1.28 for 5)

5.  Here I have soldered on the female connector for my tool stick.  Make sure to match up the wires properly.

Now that your tool stick is setup, let’s move on to soldering the connectors to your Trex 150’s MRS.

 

Align Trex 150 DFC – Attaching Male Connector

WARNING:  Flashing your Align Trex 150 DFC with BLHELI will void the warranty on your MRS controller.  Additionally, you will not be able to return the software back to the stock Align software, so continue with caution and I am not liable for any damage you may cause on your helicopter.  My process is not the only way to flash BL HELI, but is the process that has worked for me.  Please read through the whole tutorial before you decide to move forward.  As always do your research to find the other ways that BL HELI is flashed onto rc helicopters to ensure that you are using the technique that works best for you.

Here comes the tricky part.  If you have ever had to add an ESC to a BLHELI project then you must be dreading this part, but this is way easier.  There is no ESC required.  You just solder 2 male connectors to your Align Trex 150 DFC MRS.

1.  You will need to remove the MRS from your Trex 150 and disconnect all motors and servos.  The part we will be soldering to is located on the bottom of the MRS.

Here is the flashpoints labeled on the MRS.  It is very important that you match the colors while you are soldering.  As indicated in the picture, one connector will program your main motor and one will program your tail motor.

2.  Turn the MRS over so that your view matches the one shown above.  Get your connectors and push them through the gap in the middle of the MRS, then measure how far out you desire to have your connectors, and trim to size.  When you are done soldering you will need to be able to grip the connectors with your Thumb and Index finger.

3.  Next solder your connectors to the main and tail pads as indicated in the picture from Astroid Designs above.

NOTE:

Here are some small details that I learned through trial and error that I have not seen mentioned in the forums.  I was excited during this process and these are things that I really did not think about as I was going through this.  I may have to re-solder mine since I am a perfectionist.  Anyway, I hope to save you some time and grief during your process with my lessons learned.

a.  You are soldering to the bottom of your MRS, the place where you tape the MRS to your heli frame.  As you are soldering each wire try to ensure that you are soldering each connection as flat as possible.  If you do not, your MRS may not stay taped to your frame, because the tape will not be able to grip the entire bottom of the MRS as it should.  Also, if your connections are not flat, then your MRS will not be flat when you tape it to your frame.  It is very important for the MRS to be flat on the frame for flight.

b.  Typically I prefer to cover my soldering joints with hot glue to help reinforce everything during crashes and for endurance, but that will not work in this case for the same reason as note (a).

c.  I am not sure if this is a concern, but it became something I noticed.  My finished MRS below shows the connector sticking out from the front of the MRS.  If you solder your connectors so they are sticking out of the other side of the MRS they will be pressed against your main motor when you install it on your heli.  I played around with a few options, such as the connectors sticking out from the sides of the MRS.  Shown below really is the best way to attach your connectors.

Below is my finished MRS.  I have seen pictures where the connectors were not trimmed and are just folded up on the sides.  I prefer pushing them through the middle and trimming them before soldering.  It looks cleaner and saves room for future mods should there be any.  Attaching this setup to the tool stick is as easy as just removing the canopy.

4.  Now that the connectors are soldered to your MRS, you will want to check it all before you install it on your heli.  Just in case you need to troubleshoot, re-solder a connection, or you have a bad cable.

I found this picture online with the alternative servo type connectors from Hobby King showing the connections soldered.

Connecting Your Align Trex 150 MRS To Your Computer

WARNING:  Flashing your Align Trex 150 DFC with BLHELI will void the warranty on your MRS controller.  Additionally, you will not be able to return the software back to the stock Align software, so continue with caution and I am not liable for any damage you may cause on your helicopter.  My process is not the only way to flash BL HELI, but is the process that has worked for me.  Please read through the whole tutorial before you decide to move forward.  As always do your research to find the other ways that BL HELI is flashed onto rc helicopters to ensure that you are using the technique that works best for you.

Again you will want to connect your Align Trex 150 MRS to your computer off of your heli the first time just incase you need to troubleshoot, re-solder a connection, or discover that you have a bad cable.  The following walk through is my initial connection after soldering one of my heli’s.  I will also include some photos of mine put back together so you can see how easy it is to connect when all of this is done.

1.  Just like the soldering, connecting your MRS to your computer is just as tricky.  Once you do it a few times, it will get easy to remember.  For now I would take down some notes and keep them close by.  You have to connect everything in the following order or BLHELI will not recognize your MRS.  The black cable in the picture below is a USB extension cable and is not required, this allows you more room to work and lay everything flat during the process.  I recommend one, but it is not required.

– Ensure that you have a fully charged heli battery ready before starting this process.

– Ensure the BLHELI software is open on your computer.

– Okay, first step, connect your tool stick to your computer by itself.  Allow your computer time to find and install any drivers for the tool stick if there are any drivers.  The green and red lights should be illuminated before proceeding.

2.  Before going further I want to point something small out.  Since you have two connectors and each one programs a different motor, I labeled the top of my connectors.  In the photo below the tool stick is connected to my main motor (I left this one blank).  The connector that is not connected is my tail motor connector (I put a T on top with a Sharpie).  It will be difficult to distinguish them both once the MRS is installed so this well help keep you straight on which one is which.

– Next step is to connect your MRS to the tool stick.  This DEMO will describe main motor programming.  The tail motor works the same way.

3.  Next connect your fully charged battery.  Here I am using the Turnigy Nano-Tech 330 mAh battery to allow me more time for programming.  The light on your MRS will light up if all is good with your soldering.

4.  Not that everything is connected BLHELI should recognize your MRS and allow you to program your main motor.

BLHELI Flashing

NOTE:  As of 20 December 2014, I have not been able to get BLHELI Revision 12. 2 to work on my setups.  I am having to use BLHELI Revision 12.1.  You do not need to download anything else.  All of the Revisions are contained in the latest software.  Just click Flash BLHeli and ensure that you change the Revision to Revision 12.1 on the first screen.

1.  Find where you downloaded your BLHELI file.  Mine shows BLHeliSuiteBeta12200, but the software is changed often and yours may have another name.

1. BLHELI

 

 

 

 

 

 

 

 

 

 

 

 

2.  Open the file and locate the Application Icon, then open your version of BLHeliSuite.

2. BLHELI

 

 

 

 

 

 

 

 

 

 

 

3. BLHELI

 

 

 

 

 

 

 

 

 

 

3.  In the initial window that opens, notice that all of the options on the bottom are greyed out.  This is how you know that your helicopter is not connected or that there is a problem with your connections.

4. BLHELI

 

 

 

 

 

 

 

 

 

 

 

4.  Once you have BLHELI open, connect your helicopter as described above.  If all of your soldered connections are good then the bottom buttons will be selectable.

 

I apologize for the background change in the photos, I had to change computers to complete this walkthrough.  Be careful with what you click on when downloading BLHELI.  In the process of downloading it for this page, I clicked the the download button.  The BLHELI download page opened, but so did another immediately after.  I did not realize it and infected my laptop with all kinds of malware that I could not get rid of.  Some of it was so embedded that I am formatting the hard drive my laptop as I finish this write up.  I’m not blaming the creators of BLHELI, it is not their fault.  They have worked hard to bring us this software for free and I do not expect them to pay to give it to us (my next project is to see if I can just post it here safely for everyone).  Anyway, let’s get back to it.  My heli is connected successfully and the buttons at the bottom are now selectable.  This is what you should be seeing.  If not then check your connections.  First check your tool stick, then your heli.  If everything is still greyed out, then it tends to be some issue in the soldering.  If you have all the options at the bottom, then keep reading.

 

5. BLHELI

 

 

 

 

 

 

 

 

 

 

 

5.  You will always need to click Connect initially to connect the software to your heli’s MRS or ESC.

6. BLHELI

 

 

 

 

 

 

 

 

 

 

 

6.  You know all is well when Connect turns to Disconnect.

7. BLHELI

 

 

 

 

 

 

 

 

 

 

 

Sorry about this, but I have to say it again.  This is the point of no return for your Align Trex 150 DFC MRS warranty.

WARNING:  Flashing your Align Trex 150 DFC with BLHELI will void the warranty on your MRS controller.  Additionally, you will not be able to return the software back to the stock Align software, so continue with caution and I am not liable for any damage you may cause on your helicopter.  My process is not the only way to flash BL HELI, but is the process that has worked for me.  Please read through the whole tutorial before you decide to move forward.  As always do your research to find the other ways that BL HELI is flashed onto rc helicopters to ensure that you are using the technique that works best for you.

7.  To flash your MRS with BLHELI, simply click the Flash BLHELI button and we will get this going.

8. BLHELI

 

 

 

 

 

 

 

 

 

 

 

8.  When you click Flash BLHELI, you will get some options.  There is a lot to play with.  Most of it is written to control ESC’s and that is what the first option (XP-7A) is.  Just a little history before we continue so that those of you that are new and doing this the first time with your Align Trex 150 DFC.  This all started with the Blade mCP X and everyone’s pursuit to go brushless with that awesome heli.  To do that we had to solder a separate controller for the main motor and one for the tail motor to the heli’s main board (you can read more about this in detail on my mCP X webpage).  The XP-7A was a popular choice for the main motor and the XP-3A was a popular choice for the tail motor.  We are not attaching ESC’s to our Align MRS, but we are going to flash our main with the XP-7A code.  It will have the same effect.  That being said, in the next window select XP-7A Main.  Make sure all of your drop down menu’s at the top match mine, then click OK.

9. BLHELI

 

 

 

 

 

 

 

 

 

 

 

9.  You will be asked one more time if you want to flash your MRS.  You can change the flash with all of the options available if you want to, but it is important that you realize that the Align software on your MRS is about to go bye bye.  Click OK.

10. BLHELI

 

 

 

 

 

 

 

 

 

 

 

10.  You will get a status bar, then you will be told if the install was successful or not, click OK.

11. BLHELI

 

 

 

 

 

 

 

 

 

 

 

11.  Next you will be asked if you want to write the current settings, go ahead and click Yes.  You can go back and change the settings later.

12. BLHELI

 

 

 

 

 

 

 

 

 

 

 

12.  Now your MRS is flashed.  You can change the settings to suite you and your flying style.  When your settings are what you want them, then click Write Setup and that will change the settings on your MRS.

13. BLHELI

 

 

 

 

 

 

 

 

 

 

 

13.  Then you are done.  Click Disconnect.  After clicking Disconnect your MRS will beep and the button in the software will change to Connect again.  Remove your battery, disconnect the tool stick from your heli, then the tool stick from your computer (in that order!!).  Repeat the same steps for the Tail Motor, then Happy Flying!!!!

There is a lot open with BLHELI.  There really is not right or wrong and I am not going to tell you how to setup your heli.  My settings are basic and will get you in the air.  Get a feel for the changes and then mess around with all of the options to get your heli perfect to your flying style and feel.

Here are some reliable settings to start out with no matter what main motor or tail motor you are using.  These are the base that I started with.  They will get you in the air and tinkering with your own setup.  Thank you Dylon (Astroid Designs)!!!!

Disconnecting After BLHELI Flashing

Just like connecting your MRS to your computer, you will need to disconnect it all in a certain order to avoid damaging your tool stick or Align Trex 150 MRS.

NOTE:  YOU CANNOT JUST MOVE THE CONNECTOR FROM THE MAIN MOTOR TO THE TAIL MOTOR.  YOU HAVE TO DISCONNECT EVERYTHING, THEN RECONNECT IT ALL TO MOVE ON TO THE TAIL MOTOR OR VICE VERSA.

1.  First click Disconnect in the BLHELI software.

STOCK TEST INFORMATION:

I love the Align Trex 150 DFC so much that I was planning on keeping one of my two stock.  I flashed one with BLHELI and started with the stock motor first to compile information, but the heli came alive so much that I flashed both with BLHELI immediately.  I have to say up front that if you are in love with this hobby and heli, then flashing it with BLHELI is a must do modification, flashing it really does wake it up even with stock motors.  You can always decrease the settings in the software or your radio to make if feel as it does exactly out of the box and move it up as you get comfy.

The bottom line is that I loved this heli stock, but love it even more stock and flashed.  If you decide to upgrade the motors later, then the work is already done.  Stock and flashed it has just a little more power.  It feels almost the same only a bit more smooth and alive.  This one is still my first pick backyard flyer without a doubt.  I tested it with the stock battery and the Turnigy Nano-Tech 330 mAh batteries and prefer the stock battery with this setup.  Both batteries work well with this setup, but the Nano-Techs work way better with my modified heli so I have reserved the Nano-Techs for that due to the flight time.

All information compiled is based on just hovering and back and forth flying (no 3D maneuvering).  I used both V curve and flat curves in my testing and there was not any change in flight times.  When I am testing I typically fly around my backyard and land with one minute to go.  The last minute I leave my heli in high idle until the 10 second buzzer on my DX8 goes off.  This is to prevent crashing in case I run out of battery power.

Flight Times:

1.  Stock Battery – 5-6 Minutes
2.  Turnigy Nano-Tech 330 mAh – 7-8 Minutes

LYNX UPGRADED TEST INFORMATION:

I tested this heli the same as my stock build.  Normally I start with the stocker, then move on to my modified heli so that the differences are more defined.  This heli is way to heavy for the stock motor, so the information compiled is with the HP06 and HP08 main motors.  With both motors this helicopter is a handful in my backyard, but so much fun.  If I said that this thing moves, it would be an under statement.  For me the HP06 is the perfect match.  The HP08 really freakin moves!  My only complaint about the HP08 is in conjunction with the servo saver mod.  The HP08 is so big that if you crash and need to readjust your servo arms the screws are hard to get to.

The top portion of the motor gets in the way and you will have to take one screw out, then turn your main rotor to make clearance to get to the other screw.  I am also concerned about stripping since the tool is at a significant angle to clear the motor.  Additionally after three crashes with the HP08 I stripped my elevator servo gears (it is a very powerful motor for this heli).  Metal servo gears are essential at this point with the HP08 even with the servo saver mod.  That is why mine now has the Lynx Metal Servo Gears.  I am not complaining about having to upgrade the gears, I wanted to do the walkthrough for you all anyway.  This has been a big project for me, but it has been completely worth it.  This heli is so diverse and fun that after all of this, I am considering extending this heli.  We will see how it goes.

Flight times do drop considerably with both motors, but the HP08 main motor really does eat up some power.  There really is no use for the stock battery with either the HP06 or HP08 motors and the Turnigy Nano-Tech 330 mAh is a must for this set up.  Of course I have included the stock battery flight times for both motors for your viewing pleasure.

Flight Times:

HP06

1.  Stock – 4-5 Minutes
2. Turnigy Nano-Tech 330 mAh – 6-7 minutes

HP08

1.  Stock – 3-4 Minutes
2.  Turnigy Nano-Tech 330 mAh – 4-5 Minutes

More Post Flashing Information

BLHELI TAIL CONNECTOR ISSUE:

This is something to look out for with both stock and Lynx frames.  In the photo is my Lynx heli and the HP06 motor.

With the MRS installed the HP06 comes really close to the BL HELI tail connector.  Make note of this when you install yours and make sure that there is clearance or your motor will eventually eat through it.

HP08 AND LYNX SERVO SAVER ARM ISSUE:

I have been messing around with it and there just is not a solution.  Of course when I upgraded to the Lynx Metal Gears, which are essential to withstand crashes with an HP08 motor, I upgraded to the Lynx Servo Saver Arms.  I abandoned the Lynx Arms, because the pitch servo had a significant angle compared to the stock servo arms.  See my Lynx Metal Servo Gear page for more info.  The issue that I want to point out as far as BLHELI goes.  It is impossible to remove the forward servo arms after a crash to readjust the arms.  You cannot remove the servo arm screw with the included plastic washer installed.  I suppose you can do without the plastic washer, but I figure Lynx included it for a reason.  I have since reverted back to my HP06 since.  The HP06 leaves you with plenty of room.  Here are the pictures.

 

This is the HP08 and no matter which way you have the upper motor bell situated, you cannot remove the servo arms to readjust them after a slip in a crash.
