I'm working on altering some elements of the Arducopter code to add support for 4-servo, 90 degree CCPM and could use some help from developers with experience with the code base.
It seems that the only files that need changing are in AP_MotorsHeli (.

I've got an APM 2.5 with the latest x8 firmware.
I'm using a ppm receiver. I'd like to control a servo from one of the auxiliary output with a PWM signal.
Is it possible to do this (map one of the ppm inputs to a pwm output on the apm?)
Thanks
Antoine

Hi guys, ive been told off by some rather cocky arrogant people on this site for asking some simple questions not too long ago!
Basically I want to build my own quad, something that if I crash I can easily repair it. Then I was told I should buy a R
Say you wanted to build a glider to do the usual glider things. How big would you make it?
Given that fuel load is not an issue, and the mass of the APM is insignificant, would you make the wingspan 1.5 meters or 3.5 meters? Or bigger than full size?

The French equivalent of the FAA is the DGAC, they opened French airspace for commercial use of drone in may 2012.

I've just this minute updated MP to whatever version it downloaded. It restarted and worked ok. I closed it and when I try reopen it now it immediately dies.
I must be an idiot but I can't tell what version I'm running / is loaded on the APM. I look in the firmware page in MP and it says 2.74 but I don't remember updating to that.
