Hi All… new to the forum and new to Pixhawk (Hello!! )… I have an issue that is bugging the hell out of me… I have a Disco Pro that I have removed the NAZA and replaced it with a Pixhawk…everything was going smoothly until first hover…it flipped…and after reading a bit, I realized that my assumption certainly made an ass of me!.. During working this out, one thing I did was re calibrate the ESC’s (TBS 30A Bulletproofs) now my issue is that I cannot get full throttle… the Disco arms, motors spin up, but will not go to full throttle. If I re calibrate the ESC’s and try the throttle before I bring it out of calibration mode, I get full throttle, but as soon as I arm normally, and raise the throttle, it increases, but not even enough to bring it to hover…
@ScoultonLad,
Please list your version of the ArduCopter firmware and your GCS.
This issue may be a firmware or GCS issue and not a Pixhawk hardware issue and will need to be moved if it is not a hardware issue.

Thanks for getting back to me… Arducopter 3.1.5 and not sure what a GCS is but using Mission Planner v1.3.9 if that helps…
This all seemed fine until I calibrated the ESC’s… But interesting point is, that the throttle is different on each mode. Some modes no throttle increase at all, motors just spin as armed. on stabilize i can only seem to achieve 1/4 throttle and RTL steadily accelerates to full on it’s own (this is all on the bench BTW…no props)…
it’s probably something simple… but just need a pointer…
After tearing it apart and rebuilding, I’m now in the middle of trying to update firmware, but keep getting stuck at “No need to update; already onboard.”
Sorry you’re having this problem, but I’m glad for the company.
Many thanks for the pointers, I’ll give that a try tonight… The strange thing is, all I have ever had on this is Pixhawk is 3.1.5, and the throttle was working OK until I calibrated the BulletProof ESC’s (troubleshooting a schoolboy mistake with the motor order)…
I’ll go through the steps in your other thread, and report back in both threads on the outcome,…
I flew fine for a week before my baby burped.
I don’t know if I updated firmware without knowing it, or what.
I don’t think ESC calibration had anything to do with it.
Overnight, after a hard landing in Stabilize, my throttle got lazy.
I’d like to hear how it works out for you. And I want to know when / if it’s safe to move back to 3.1.5
