You can view Recharged as a sort of DLC (although it works fully on itself). There were several reasons I decided to make Recharged a separate version, one being that the file size of the original needed to be kept small, and, it was necessary to keep it running reasonably smooth even on older hardware and mobile devices. With Recharged I wanted to be able to work without restrictions and add as nice looking sceneries as possible. Email fpvfreerider@gmail.com.

Does it crash at any particular moment?

1b: If the automatic stick detection gets the sticks messed up, you can click on the little circle that you see is the correct one (instead of clicking OK) when going through the calibration procedure.

Glad that you are able to use it on your laptop at least. I'm sure you will find that any practice you put in will pay off later in real life flying.

1. I remember a few other Linux users had the same problem, at least one can be found a bit further up in this thread. Don't know if he managed to find a solution.

It should automatically keep the calibration (as well as other settings) in Linux as well as on all other platforms. You can alter some values in the custom settings menu and see if those are being saved. If not, perhaps you can investigate so that there is no permission issue that keeps it from saving (I'm not familiar how these things work in Linux). (In linux I believe the Playerprefs are stored under "/home/your user/.config/unity3d").

Good thing that you at least managed to get it calibrated properly. As you probably noticed - if one axis is reversed, you can simply reverse it in the trim settings (Click "Calibrate Controller" on the main menu and then "Skip to trim settings")

My guess is that the whole thing has to do with the joystick drivers on Linux not being consistent in some way.

Some Linux users seem to have success using this program: https://github.com/Vantskruv/wejoy

2. In Windows there's a command line parameter -"adapter N" that can be used to select which monitor you want to run it. That only works on Windows though as far as I know. Hopefully someone who is more knowledgeable in Linux will be able to chime in.

( Here is a list of the runtime command line parameters: https://docs.unity3d.com/Manual/CommandLineArguments.html )

The Turnigy Evolution most often seem to simply work plug&play. You might want to try and see if you can calibrate it as a joystick in Windows own calibration, just to see if it is properly recognized. (In the Control Panel).

Also you might check:

- Make sure you don't have any other joysticks/controllers connected, that might cause a conflict.
- Uninstall vJoy and Smartpropoplus if you have any of that software installed. Their driver messes with things when connecting via USB.

The Android version is available on the Google Play store only:


There is also a free trial that you can use to see if it works on your device:

Yes, the ability to edit/load external maps would be really great. It's not easy to make though but I have started to look into the possibility. Thank your for your feedback and suggestions!

Yes it works just fine offline.

If you already own the parrot flypad controller you can try the free android version to see if it works.


A lot of people are using their regular RC radios connected directly via USB or a USB dongle using a USB OTG adapter. (You can also try an Xbox or Playstation controller if you happen to have one of those laying around, although such gamepads don't really provide the fine control that is optimal for quadcopter flying).

Glad to hear it working great on your other computer. Thanks!

I understand, and I appreciate that. Well, sometimes it helps to update your graphics and sound card drivers to the latest version. You can also try running the simulator in a window as described in the manual and see if that makes any difference.

Did you try the demo first, does that work?

What controller/cable/dongle are you using and on what operating system/computer are you running it on?

That's right FPV Freerider is distributed as a Linux executable, not a package so you should just be able to double click it. There is some more detailed info that you get when you download it.

Glad you got it figured out :)

You can have a look in the FPVFreerider_Data folder for a file called "output_log.txt" for clues. (Or send it to fpvfreerider@gmail.com and I will have a look at it). Sometimes it helps to update the graphics card and sound card drivers to the latest version.

What computer and operating system are you running it on?

You don't have to uninstall the demo version first. In fact it's possible to keep both installed at the same time, since it just executable files.

Thanks, I will see if I can get that scene better optimized later on. Yes there is baked GI along with realtime light (for the quads shadow), that is what separates it from the other scenes.

Thanks for reporting. I think you might be right that it has something to do with the GPU. 

Have you tried running the simulator at the lowest graphics quality setting? (It's in the main menu)

The factory and forest levels are the most demanding ones, perhaps the GPU is simply struggling to achieve high enough framerate.

Also, the factory is using more memory since it has baked lighting included.

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.

If none of the above works you could try to connect an ordinary 3.5mm audio cable from the trainer port of the transmitter to the audio-in (or mic-in) jack of your computer, along with a software called Smartpropoplus.
There is more info on that in the Spektrum setup tips document:

Great, glad to hear you found the solution! Thanks for sharing, that might be helpful to others who might encounter the same thing.

It might be that you need to change some settings on the transmitter itself. I found this info on another forum:

"For Futaba 18SZ - You'll need to configure the Trainer Port function;
Linkage menu > Trainer 
Teacher/Student - Student
Channel mode - 8 Ch

Both stereo and mono adapter cables appear to work with the Futaba trainer port, however caution is required here. A correctly wired adapter when installed turns the Futaba 18SZ and 14SG on. "

Yes, on Windows you can either press Alt+Enter, or add " -screen-fullscreen 0 " to the command line of the executable. 

Not sure what the equivalent on Mac is, I don't own a Mac myself, hopefully some Mac user will be able to chime in with an answer.

I think he must have edited out the transition trip back as you say, since it is currently not possible to restart anywhere else than at the beginning. I will consider if it would be possible to implement restarting at different spots in a way that would work well.

There's no upgrade price, they are treated as two completely separate versions.

Hi, I haven't heard of that particular issue before. When you are in the trim setup, it shows the stick input that it's reading. So the jumping you describe is the same that's causing the random input when flying too.

If you aren't experiencing that erratic input when flying for real then I guess there is nothing wrong with the transmitter. Might have something to do with the USB dongle (or USB drivers) perhaps.

I would suggest to try another dongle if possible, or, to try the Smartpropoplus method described in the manual and see if that helps.

Not sure I understand - can you navigate the menu with the mouse cursor when the transmitter is turned off? But as soon as you turn it on, the cursor disappear? Does it matter if you run it fullscreen or in a window? (In Windows, you can switch between fullscreen/window by pressing Alt+Enter, not sure if it is the same on Mac)

I have some interesting things I would like to add.  Don't want to say anything specific though, in order to avoid unnecessary excitement/pressure. Since the things I want to add are a bit tricky to get working perfectly I will announce when/if it gets finished.

Posted in after buy

Yes you will have access to any coming updates.

Thank you for sharing your solution/settings!

It's already possible to do that with a workaround. You can map keyboard shortcuts to a switch/button on your transmitter using a software such as this:

Windows: http://joytokey.net/en/

Linux: http://www.lgdb.org/tool/antimicro 

Mac: http://alternativeto.net/software/joytokey/?platform=mac

(Keyboard shortcut to start/stop/restart timed race is "t")

Glad to hear that fixed it. 

If the realflight usb adapter won't work with your dx6i the smartpropolus method described in the manual might.

That is an issue with Unity's input manager (The sim is developed in Unity). It seems to be more pronounced on some devices/operating systems. I have been unable to find a solution. the best workaround I found for now is to add a small delay so that the player has time to move the stick a bit so that it "wakes up". (It just needs to be nudged a small amount).

What operating system are you running it on?

Did you try to restart your computer/device?

Thanks for reporting back. I'm glad you found the solution, I'm sure it will be of help to others!

Try to re-download the entire zip and see if that helps.

You can also try a different unzipping software if it still doesn't work.

You might also try unpacking it to a different folder on your computer.

(It is correct that there should be a "FPVFreerider_Data" folder next to the executable).

As for the email address, please email support@itch.io. They handle all the downloads/purchases, I'm sure they will be able to help.

(Here is some more info on purchases etc https://itch.io/docs/buying/al...)

Thanks for reporting back, I'm glad to hear you got a new one and that it's working fine!

Since I don't own an Evolution I'm not the best to give specific advice on that radio. But, if you go into the device manager I do believe you should see something like a joystick or HID-device when you connect it, if it's working correctly. Maybe you can find some info in the manual of the radio.

Yes, I have plans to add something like that later on. Thank you for your feedback and suggestions!

Thank you for the added suggestions, you have some good ideas there. I will add it to my list.

In FPV Freerider Recharged you can record your flights.

It doesn't matter what view you are in, you can record both LOS and FPV view. And when you replay the recording you can also freely switch between LOS and FPV.
