I'm having trouble with the Interlink Plus controller (comes with RealFlight, but not the latest Elite version). I had trouble getting FPV Freerider to recognize all of the channels at first, but after multiple tries re-opening the application, it eventually let me calibrate and worked great. This lasted a couple of weeks, and now it's not recognizing the throttle/yaw again. I've tried dozens of times with no change at all. I've paid for this, but it's unusable now! The controller works fine in RealFlight as well as calibrates correctly in Windows Control Panel. Thank you.

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.

@olevelo - I use a HOTAS for other flight sim games. If you have one connected, the OS usually recognizes it first and prevents the Interlink controller from being recognized.
