THEMA:

Would like to have Satellite using EXbus protocol rather than PPM.

Having the satellite connecting in PPM with main receiver is a severe limitation in terms of security when you need more than 8 channels.
Switching the RSAT in more than 8 channels and then you start having choppy servos movements when main receiver lost signal.

This is must have as of today the solution provided today using one receiver and one or two satellite is pretty unsafe !
