Aussage eines Chinesischen Walkera Distributors hier zu:

"Transmitters implementing a so called "Zhen Hua 5-byte" protocol. It seems that such transmitters were only made for Fixed Pitch helies, they only have 4 channels (the switches and knobs on top of the transmitter are not connected anywhere). Zhen Hua supporting transmitters can work with a simple 4-wire cables as the TX encoder chip generates digital signal compatible with PC serial port. These transmitters are supposedly no longer made.

Transitional modles--Zhen Hua support was dropped but no signal was sent to the trainer connector yet. We have a one year old 22A transmitter of this type. Such transmitters won't work with ANY interface unless hardware modifications are made to the TX board (a couple of wires soldered).

Supposedly, all new Walkera transmitters send PPM signal to the trainer connector. Even newer 22A transmitters are reportedly made this way (though, we haven't had a chance to test newer 22A), #35 and 36 were proven to be of this type. One of our microchip based interfaces, capable of deciphering non-standard Walkera PPM implementation, is needed for such transmitters."

Vielleicht ist das ja für jemanden Interessant
