Hi, I built this quad a couple of years ago with a KK board and cheap ESCs, it flew fabulously, tho my remote skills are still pretty much non existant.
So, now, it runs on the ground with APM2.8, but I can’t go any higher as it flips…
I have checked the cw/ccw of the 910kv NTM motors and their correct position for H layout, and everything has been corrected there, I am sure. The motors are powerd by 30A Proflight SimonK ESC’s which seem to be calibrated.
The motors/props are well balanced and as they spin up they are smooth, quietly hum all the way up to 50% where the machine is very close to lift off, then their is vibration from the ground, if that can effect anything?
This has benn puzzling… When I connect to Mission Planner, their are good comms… However, the front to rear axis (which is along the cross bar in the H Rear > H > Front ) is reversed, and so the Artificial Horizon points downward when the front is pointed to the sky. Yaw and Roll seem OK… I can just rotate the
I have gone thru the Compass setup several times and it seems to work, tho it only takes a short while, approx 3 single rotations about each axis and it’s done (youtube video shows this taking several minutes???)
ALSO… I have external compass/GPS, and have not done anything phyical to the board or installed any jumpers. I have taken the machine outside, connected to laptop, and cannot get a GPS fix , blue light keeps flashing???
A freindly voice occasionally tells me “Disarmed: get 3DR fix” or something.
So, apologies for my ramble, if you’ve made it this far, thanks! If you have any ideas, even bigger thanks!
(I shall attempt to get some sort of data log if I can, and can post video if it would help)
