Spektrum DX8 Review

Spektrum DX8 Radio (8 Channel)

Spektrum DX8 Radio

The Spektrum DX8 Radio (8 Channel) was my first real RC radio.  I am still quite new to this hobby and some items are expensive such as radios, so I can only compare the DX8 with my DX4e which is not really a comparison.  It was a bit intimidating stepping up to this radio from the DX4e.  There are way more switches and settings, settings, and settings.  Overall I LOVE THIS RADIO!  Take some time and read the manual.  Take your time learning it, you will not be able to just go as soon as you pull it out of the box if this is your first real radio.  Go here and watch Finless Bob’s Videos.  This radio introduces you to how complicated this hobby is, so my biggest piece of advice is to take your time learning it.  Despite all of the negative feedback when the radio was first introduced, Spektrum did fix all of the kinks and this radio is a beauty to use.  I am glad this was my first.  I will compare all of my future radios to this one.  I am truly grateful for everything that this radio as taught me and how it still operates like a dream.

I was skeptical at the price of this radio, but new that I was hooked on this hobby and that I am here to stay so I went all in.  It was a good investment and I have yet to regret this purchase.  It works with all my helis:  Blade MSR, Blade mCP X, Blade mCP X BL, Blade Nano CP X, Blade Nano QX, Blade 130 X, Align Trex 250, and even my Parkzone F-27Q Stryker 180 airplane.  The radio even works flawlessly with my flight simulator Phoenix RC.  There is not much else to say other than this radio is AWESOME!  It completely ROCKS!  It is all that I hoped it would be and then some, so if you are on the fence about it don’t worry.  The Spektrum DX8 is worth the dough and will keep you flying time and time again.  My only complaint so far is the stock battery that comes with it.  I will get into that below and what you will need to take care of the issue, which really isn’t an issue.  Just a bit of BS.  I’ve put off this page due to the amount of information.  There is a lot so keep coming back for updates.  If you would like to request specific information feel free to email me and I will get it up here as soon as I can.

Spektrum DX8 Stock Battery

The stock battery does what it is supposed to, but it is sub par compared to the upgrade offered.  Makes me wonder why they just don’t sell the radio with the better battery.  Anyway, here is the run down.

1.  Here is the Spektrum 2000mAh 4.8V Battery that the radio comes with, which does it’s job.  There is a better alternative though that you will eventually get.  Everyone wants to know why the radio just doesn’t come with the better battery.

2.  Here is the quite pricey better alternative.  With the Spektrum 4000mAh 7.4V Battery I charge my radio maybe once a month, just saying.

Spektrum DX8 Software Updating

1.  First head over to Spektrum and create an account.

2.  Next you will need a SD card.  I have two.  I use one for all my heli profiles.  I use the second card just for updating.  If your computer doesn’t accept SD cards you will need an external reader.

3.  Once you have your SD card ready to go, log in, and bounce over to the DX8 webpage.  Click on the Manuals and Support tab.

4.  Under the Manuals and Support tab, click Check For Updates.

9.  Leave your downloads window open and then open a window for your SD Card, then drag and drop the file to your SD Card.

10.  Now you can close all windows and remove your SD Card from your computer.  Grab your radio and back up any models that you have stored on your radio’s internal memory.  Insert the SD Card that contains your update.

11.  With the SD Card that has the update installed, all that is left is to simply switch on your radio.  The radio will do the rest for you.  Once you flip the on switch the update will install by itself and you will see a status screen showing the installation’s progress.

12.  When the installation is complete the radio will go back to your home screen and the last model you were using.  Now you can remove the update card and get back to flying.  It is good practice to test all of your models after updating to ensure all settings still work as they did before.

Spektrum DX8 Stick Adjusting

These are the steps for adjusting the tension of your radio’s sticks.  Some like them loose while others prefer some tension in movement.  My radio’s sticks were fully loose out of the box and to complete this article I adjusted them to full resistance.  I went back to fully loosened, because that feels more natural to me.  It is all a matter of opinion and your preference.  Anyway, here is how you adjust them.

1.  Turn your radio over so that you are looking at the back.

2.  Remove the back rubber grips.  They are slightly glued so you will need to force them a little.

3.  There is a third port toward the top right.

4.  Once the rubber is removed you will need a phillips screwdriver to adjust the tension.  On the left and right grip sections the screws are labeled by arrows that demonstrate the direction that the tension will be applied to that stick.  Now you just have to play around with them all until the sticks feel comfortable to you.

5.  When you have the resistance to your liking, just firmly push all the rubber back in place.  I did not apply any glue to mine and they stay secured without it.

Spektrum DX8 Stick Swap

The radio sticks are about comfort.  If you fly with your thumbs then you will most likely want short sticks.  If you are a pincher you will probably prefer longer sticks, or maybe you just love bling.  Whatever your fancy, swapping the sticks on the Spektrum DX8 is a breeze.

1.  Grip your stick and twist it left (counter clockwise) to loosen it up.

2.  Once it is loose keep twisting left (counter clockwise) until it unscrews completely then remove the old stick.

3.  Now install your new stick by twisting it on to the right (clockwise) until hand tight.  Do not over tighten and that is all there is to it.  Happy Flying!!

 Spektrum DX8 Setups

The setup up for heli models are a matter of preference in the end.  You will need to play around with them in order to match your style of flying.  There is of course basic settings that need to be there in order to get your heli in the air, but other than those; the sky is the limit.  Basic settings will usually be listed in your heli’s users manual.  Spektrum also has basic model profiles that you can download to a SD Card just like updating the software.  As I have time to input mine, I will share my settings on this page.  If any of you would like to share your settings in one place feel free to email them to me and I would be happy to throw them up here for everyone’s benefit.

1.  Spektrum’s Basic Setups Download – Just download the file to your computer.  You will need to unzip the file before using it on your radio.  Unzip it, then transfer the unzipped files for the models that you need to your radio’s SD Card.  Insert the card in your radio and you are ready to ROCK!!!

2.  Go here for a tutorial on how to properly setup zero pitch using the Spektrum DX8 Radio.

3.  Go here for a glimpse of the Spektrum DX8 Radio’s Gyro Gain Menu and setting it up with the Blade mCP X BL.

4.  My Settings:

Spektrum DX8 Model Files

Here are my DX8 Models.  I am still fine tuning some of them, but these will get you in the air.  Radio settings are about preference and feel, so feel free to change and tweak to your needs.

NOTE:  My web host does not allow .SPM files.  I have changed the extension to .doc, so after you download a file you will need to rename it and change the extension back to .SPM before loading it onto your radio.

Spektrum DX8 System Settings

I thought I would throw some of the system settings that I have found.  One of the reasons is the idle alarm.  There is nothing like laying my radio down for a few while I run in the house to make an adjustment or two with my heli, to return to an annoying loud beeping and vibrating radio.  My dogs freaking out at the disturbance.  I know, I know why not just turn the radio off?  Sometimes you forget or a quick adjustment turns into more time than you expected.  Either way you can adjust the time in the system settings.  I’ve added this setting with a couple more that should come in handy.

1.  First you need to enter the System Setup Menu, hold down the wheel/scroll button on the right while powering on the radio.  The System Setup Menu will be the first screen once powered on.  Scroll down to the bottom until you see System Settings.

2.  Click on System Settings and you will see the screen below.  With this menu you can adjust the display screens Contrast.

Spektrum DX8 (4)

 

 

 

 

 

 

 

3.  Also on this menu you can change to different Modes 1-4.

The difference between radio mode 2 and 4.  It sounds complicated, but it is actually very simple.  There are actually four different radio modes.  They are simply 1, 2, 3, and 4.  The different modes basically cause the sticks to change which servos that they control.

The different modes, looking at the front of the radio.

Mode 1

  • Left stick controls (Elevator/Rudder)
  • Right stick controls (Throttle/Aileron)

Mode 2

  • Left stick controls (Throttle/Rudder)
  • Right stick controls (Elevator/Aileron)

Mode 3

  • Left stick controls (Elevator/Aileron)
  • Right stick controls (Throttle/Rudder)

Mode 4

  • Left stick controls (Throttle/Aileron)
  • Right stick controls (Elevator/Rudder)

Bet you did not realize there could be so many combinations.  Now that modes makes sense, realize that most US radios are setup for Mode 2 by default.  There are different mode standards in different countries.  I am trained for Mode 2, but feel free to play with it and get used to the mode that you are more comfortable with.

4.  Scroll down to Next in the bottom right corner and click it.  That will take you to the next menu of interest the Extra Settings Menu.  Here you can change the Inactive Alarm time by highlighting it, clicking it, the scrolling to the setting that you desire.  With this setting you will need to immediately back out of the System Settings Menu, then go back if you need to make any other changes.  At first I was unable to get the setting to save and that was why.  You have to back all of the way out of the menu immediately in order for it to save.
