I'm pleased to inform the owners of this Tx that version 3.3.0 now supports Walkera PCM transmitters.
The project was carried out with the help of Anton Heiss of , Germany, who kindly sent me a sample Tx all the way to Israel, on his expense. Also, Hans-Friedrich Fuge was very helpful in suggesting the project and in testing it.
AFAIK, this is no other product that enables you to use this Tx as a joystick.
