Here are some general suggestions that often help when one channel is not recognized:

- Make sure you don't have any other joysticks/controllers connected, that might cause a conflict.
- If connecting via USB, make sure you uninstall vJoy and Smartpropoplus if you have them. Their driver messes with things when connecting via USB.
- Make sure you have "Heli" selected as model type on your radio. ("Plane" generally doesn't work very well).
- If you are using a USB dongle - check if there's a switch on the dongle where you can select different modes.
- Perhaps you can remap the output channels (in the menu of the transmitter) so that it sends to another channel.

As for your mic port problem, it sounds like there is some kind of dead zone activated. First of all, make sure that dead zone is turned off in the main menu of Freerider. Second, check if you can turn off the dead zone in the software that you use.

Btw, some Taranis users on linux are experiencing that there is always a dead zone by default. It needs to be turned off by running:

" $ jscal -c /dev/input/js0 "

michael4190's suggestion on how to measure is good. The rotation speed depends on many factors (mass/angular drag/rates...) and it's currently not possible to simply enter the rotational speed value in degrees directly in the sim.

The android version is separate, it is only available on the Goggle Play Store.


It needs to be purchased separately.

There is also a free version that you can try to see if it works on your setup.

In what way are you unable to get it working properly? 

Can you describe the noise on the screen that you are experiencing?

Great, I'm glad to hear you got it working!

You can request a new download link here:


(It's under "Recover purchases")

You need to use the same email address that you used when you purchased it, it is linked to your account.

If you still doesn't manage to get it sorted, email support@itch.io. They handle all the purchases, I'm sure they will be able to help.

The Windows/Mac/Linux versions are all available as one purchase.

The Android version is a bit special though, it's only available on the Google Play Store and needs to be purchased separately.

I had a look at the log file but I couldn't see what's wrong. What computer are you running it on?

Thanks, glad you got it solved!

When you check the movement of the sticks on the trim settings screen, does it act correctly?

(You can go directly to the trim settings by selecting "calibrate controller" on the main menu, and then "skip to trim settings")

See if your graphics and sound card drivers are up to date, that often seem to help.

Also, you could try running the simulator in a window as described in the manual and see if that makes any difference.

You might also check the "output_log.txt" in the FPVFreerider_Data folder for clues.

Great, glad you got it solved, thanks for sharing the solution!

The green frame might be your antivirus software that is sandboxing the program.

If so, you should be able to mark FPV Freerider as safe, or, turn off the sandboxing, you have to check how to do that on your antivirus software.

If you are able to move the little white circles on the calibration screen smoothly up and down, that's a sign that it's working.

If the automatic stick detection gets it wrong, you can click on the circle that you see is the correct one (instead of clicking "ok").

When you get to the trim screen, you will be able to see if the stick movement is recognized correctly.

And, in case you haven't seen it here's a document describing how you need to setup the Taranis for it to work correctly on Windows:


Thanks for sharing!

That would be possible. I have actually plans to look into Google Cardboard support, but I have been to busy to get into that right now.

(For now, it is possible to modify a cheap VR headset by removing any internal divider and putting in a single large fresnel lens instead of the two separate lenses. That way you get the entire picture, like you would in box-type FPV goggles. I guess it is a bit overkill for most people to go through that trouble though).

Awesome, I'm glad to hear that, thanks for reporting!

Yes it exists right here:


Haven't heard of that issue before. You could try running the simulator in a window and see if that makes any difference. You run it in a window by adding command line parameters to the exe file, try this:

-screen-fullscreen 0 -screen-width 640 -screen-height 400

The main difference is that there are some larger and more detailed sceneries in Recharged. Also, there is some extra functions such as flight recording and the ability to move the LOS viewpoint.

It is also quite a bit more demanding graphics wise, so it needs a bit more powerful computer to run smoothly.

Great, glad to hear that you managed to match it!

Thanks, yes I agree about Joshua Bardwell's house :)

There's no deal currently, it's a separate purchase. There are several reasons I decided to make Recharged a separate new version, one being I needed to keep the original a small file size. With Recharged I wanted to be able to add as nice and detailed maps as possible without having to worry to much about file size and graphics limitations.

Glad to hear that you like the feel of it. I'm not sure how you would replicate it on your quad since the expo is just one of many variables. The built in expo in Freerider is a pretty straightforward x^2 curve. The rates is what affects the flight characteristics the most, in the full version you can play around with the values.

When you go through the calibrate controller procedure, are you able to move four of the little circles smoothly up and down? Sometimes the automatic stick detecting fails, in that case you can click on the little circle that you see is the correct one (instead of clicking "ok)".

For most people the Turnigy Evolution seems to be plug and play. In what way do you mean that the controls are all over the place?

(To calibrate for mode 1, keep an eye on the top of the screen. For example when it says "throttle up", use the stick you want to assign for throttle, etc..)

Glad to hear that you finally got it working! Thank you for sharing the information, hopefully that will be of help if someone else runs into the same issue.

Might be included later on. It's not on top of the to-do list though. I agree it would be great to have.

You only need to download one file.

Choose the one for your operating system. Choose the latest build.

When the zip file has downloaded completely, unzip it to a folder of your choice.

It will look a bit different depending on the operating system -

On Windows, it should be a FPVFreerider.exe file and a FPVFreerider_Data folder.

Double-click the exe file to run the simulator.

Great, glad to hear you got it working!

In LOS you can have autozoom enabled to get a bit better view of the quad far away. Autozoom is selected in the custom settings.

It still gets small pretty quick though. In Freerider Recharged there is also the ability to set the LOS viewpoint position.

The best map in Recharged for beginners is Rocks, there you can find pretty open flat areas and also some obstacles.

In Freerider classic there is the Desert, Meadow and Two Towers which are pretty simple.

(I have plans for some more maps for Recharged later on, one of them being an open field).

Ok, well at least you tried it thoroughly, I guess you might be right that Unity can't read the Thrustmaster properly.

Glad you're able to use your transmitter through vjoy instead.

The built in expo curve in Freerider actually acts pretty much like in the picture you attached (boosted end movement).

On the trim settings screen (that's under the calibrate controller menu), does the stick movement behave as expected - and by that I mean, does it have good resolution/fine control over the whole range, and does it reach all the way out to the corners of the box in all directions?

You could try to download the zip again in case it's some rare situation that it got messed up somehow. Otherwise, it sound like a permissions thing to me. When you performed suggestion #4, did you get some kind of confirmation that the command was executed? I don't own a Mac myself though, so I hope some Mac user will be able to chime in.

FPV Freerider does not have the ability to read the values directly, it goes though Unity's input manager (That is used when developing the sim). I can only see that values that is coming through that input manager.

Is your Thrustmaster connected directly via USB, or does it have some other kind of connection/driver?

How do you mean that the things it said to try didn't work?

Do you mean that you managed to do them, but it did not make a difference, or, do you mean that you were unable to do them?

Here are some general Mac tips that are also in the manual:

1. If you unzip the file on a Windows machine and transfer the file to your mac with a USB stick it should work.

2. Better solution for anybody else who has this problem. OS X is picky about which programs can be run (the first time) by double-clicking. To run a program that says "this can't be opened", right-click the icon and choose "Open". You'll be given an option to open the program, and from then on it won't bug you.

3. For Mac's having trouble installing FPV Freerider try going to the Mac's System Preferences>Security and Privacy> General Tab and check the box "Anywhere" to see if this allows your Mac to install FPV Freerider.

4. So i have banging my head with frustration about not being able to even open the program in OSX 10.10. I have finally solved the problem for anybody who is still having the same issue i was, you have to open up terminal and type chmode +x (fpvfreerider.app) and that should do it. Hope this helps anybody.

Often it has to do with the graphics card drivers. Make sure both your graphics card and sound card drivers are up to date.

You can also check the "output_log.txt" in the FPVFreerider_Data folder for clues, or send it to fpvfreerider@gmail.com and I will have a look and see if I can figure out what might be the issue.

FPV Freerider classic:


Android version of Freerider classic:


For those that wish to have very fine control over the expo curve, I recommend doing it in the menu of the radio itself (if available).

In Freerider you can select "linear" in the custom settings, and then tune the curve on the radio itself to get it exactly as you wish.

It's described in the manual. You do it during the calibration process. Keep an eye on the top of the screen - when it says "throttle up" you move the stick that you want to use for throttle, and so on.
