So I finally put together my quad with the APM2.5+ and have flown it a few times and while I am flying it there is this random twitch where the quad rolls to the side just for very b
Hi I have done all the wiring but no power to rx. I am using apm 2.5 with power module connects to a 3s lipo. Do I need to put in a jumper plug? Coz the cable from esc goes to the output side of the apm. New to all this and close to flying. Please he

May I begin by saying what a valuable forum this is, although this may be my first post I’ve been following various threads for a while and there is nowhere else on the internet with such a mix of high level technical expertise and accessible

I have the APM 2.5 with compass on board mounted at yaw270 using Board Orientation (AHRS_ORIENTATION) but haven't touched the Compass orientation (COMPASS_ORIENT).
Should COMPASS_ORIENT also be orientated? or is this just for APM 2.6 when th

Hi all,
I would like to hear from people who have used the HMC5883L and the MPU9150 (AK8975). While trying the sensors as a compass, we realised that the 9150 was very noisy and varied between -2 and 2 degrees about a mean value while the hmc was more

I'm trying to download the logs from the flash on the APM 2 (v2.73) using the CLI tool in Terminal...it doesn't seem to be possible.
I've tried the sequences below, but they all seem to be inhibited by the incredibly long connection process t

I have another Quad that flies perfectly. It comes back when it is "called" and flies very nicely.
The 3DR is a little larg
Read more…Remembering our physics we know that a = F/m.
With that in mind, I figured one of the best ways to reduce vibration (which is proportional to a), would be to increase the mass of the APM. To that end, I taped together a stack of 4 US quarters and sti
