Hi, I try to make all the steps of the manuel for failsafe instruction. But I had no success.
Has anybody the same configuration, and failsafe is O.K???
Thanks and regards
Robert

Hi all,
I have a APM 2.5 with the latest firmware. It worked great up to the point that I changed TX. I used a Hitec A9 before. I sold it and bought a Graupner MC-32.
I have gone through the setup and it seems to go through the TX calibration process just fine. I calibrated the ESCs fine. For the life of me I cannot get to arm the APM board and get the motors spinning. I make sure to be in the stable mode prior to trying to arm.
Also, I noticed a drift with the GPS when the Quad is not even flying. So I get 3D lock with 9 SATs but on the map it shows that the quad is moving, where in actuality is not.
Anyone else had any issues getting the Graupner radios to work with APM, or do you think that there is something wrong with the controller board?
I updated to the new firmware and APM Planer and now I have a suspicion my radio is creating some kind of problem with the APM Fail Safe. APM Planer keeps on giving me a voice message " PreArm: CheckFS_THR_value". So I have tried to set the throttle Fail Fafe.
I set the Fail Safe with the Planer, but it does not seem to make any difference. I am frustrated. I'm sure it is something simple, but I am not seeing it. I must not be doing it right.
In my frustration this morning I ordered a newer board version APM 2.8 with a GPS hoping that it is the board. Any way, any help will be greatly appreciated.
Thank you
I experience exactly the same issue. Having 1 Graupner MZ-24 bould to a GR-24 talking to the Pixhawk running the latest firmware.
The GR-24 output all sensor signals + SUMO so just for a test I connected a servo on CH3 (Throttle). This servo moves to FailSafe position when powering of the transmitter but SUMO output remains. This seems to be a Graupner bug!
There is another thread about this here: http://diydrones.com/forum/topics/pixhawk-and-graupner-mz24-gr24-pp...

I got it working :-) Watch the thread in my previous post.

I have the Graupner MX12 and had same trouble,
I started a new model and left the fail-safe on the MX12 to be determined later ( TBD )
If you don't start a new model you can't undo the fail-safe.
Set fail-safe in APM 2.5 only.
Hope this helps

I have the same problem but I use ArduPlane 2.74b, APM2.5 and Graupner MX-12 Hott 6 channel TX/RX. To configure Graupner and APM seems to be a problem.. I hope I find someone who has done it..
