Hello world,
today we have found same reasons for the malfunction:
1. One digital servo (elevator) stop moving and hang sometimes by
collection to receiver or tiny13 . Connecting to a spectrum 2.4GHz
the servo work without problems.
Has someone had trouble with digital servos by using a Graupner
35Mhz transmitter? Is the impulscheme other than by analog servos?
2. Compiling with an old Siemens laptop results in a wrong object code
in the LPC2148. There were no error massages given. By using a new
laptop compiling the same sources we found no malfunction.

Dear Christophe,
tanks for the information.
We use 868 MHz and will test the ACT-reciever from Mikrokopter.

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.

Hi,
we are flying the following configuration:
Graupner MC22 (9 channel impulses),
Profi Penta RC- receiver,
Tiny13,
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:
Tworg,
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?
Regards
Heinrich Warmers
