Since it works on your desktop computer it should work on your laptop too. 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 installed. Their driver messes with things when connecting via USB.
- Make sure you have "Heli" selected as model type on your radio. ("Plane" often doesn't work very well).
- Perhaps you can remap the output channels (in the menu of the transmitter) so that it sends to another channel.
You could also simply try plugging it into another USB port and see if that makes a difference.
