Hi,
I am using APM:Copter v3.4.2 together with QGroundcontrol v3.0.2 on a pixhawk - I want to deploy a parachute. I configured channel 7 on my radio to trigger the parachute, which seems to work (according to the log messages, which says "Info: Parachute: Released" and the buzzer goes grazy) but the servo connected to AUX01 doesn't move.
Any Idea whats wrong?
I have attached screenshots of all settings I have made relating to the parachute.

Hi Janne. In my case I just forgot to connect a ESC/BSC ... the pixhawk doesn't have a supply voltage on its AUX outputs! After I supplied it, it worked, as described here:

No, I don't use a skycat parachute system. I am working on my own -> www.dronerescue.at
Hi Markus! How did you manage to fix this? Are you using skycat's parachute? I have similar problem to you, trigger works through rx but not through FC. I have pixhack with newest arducopter and everything is set according to ardupilot's page. I also have 5v bec powering the servo rail since pixhack has some failure powering it.
OK, I found it ... The output level on AUX1 is 3.3V and I guess my servos i was using, are 5V. I am lucky to have a oscilloscope to check it.
So everything is working as described on the wiki pages!
No one?
Other thing I came across. There is the parameter CH7_OPT which can be set to "Parachute Release" and the parameter RC7_FUNCTION which can be set to "Parachute" ... what's the difference?
Is CH7 the function for input (from the receiver) and RC7 the output (to servo)?
