* Driver to use 4CH RC transmitter using Zhen Hua 5-byte protocol (Walkera Lama,

*
* RC transmitters using Zhen Hua 5-byte protocol are cheap four channels
* transmitters for control a RC planes or RC helicopters with possibility to

* Data coming from transmitter is in this order:
* 1. byte = synchronisation byte
* 2. byte = X axis
* 3. byte = Y axis
* 4. byte = RZ axis
