The Penta Profi is not a good receiver in the presence of noise. E.g. with our 868MHz longrange modems we start getting very significant interference at 100m and at 300m loose control. Other receivers like the one they sell at mikrokopter are far less sensitive to this.

we are flying the  following configuration:
Graupner MC22  (9 channel impulses),
Profi Penta RC- receiver,
25A Hype bruschless controller,
3 Hitec digital servos.

In  manual and auto1  mode we lost often and sporadic the control  over the aircraft.
The result is a crash.
It seems that the servos make maximum ways and the neutral setting is wrong.

For a configuration with:
MC16/20 and MC15 (8 channel impulses),
Hitec-RC-reciever and
2 Hitec analog servos
we have never seen a malfunction.

Has someone a idea how we can find the error?
