Ive been trying to get this build to fly reliably for a couple weeks now, not really sure what I'm doing wrong since my other builds have been mostly successful. Its a diatone et150 frame, diatone d12 12a opto escs that came with blheli, cheepo readytosky 1306 motors, cc3d using open pilot and a pdb with a 5v bec step-down, flysky fs-t6 transmitter with matching receiver. The problem I'm having is, after bringing her up to hover it'll randomly flip, sometimes after 1 minute sometimes after 30 seconds, when i bring it up a bit and try to roll or flip, without fail it will belly up and fall down, when it falls its always still armed but i will sometimes have to unplug the battery before i try to fly again because the escs are sometimes out of sync. hope this makes sense to someone here and i can get some solid advice! oh and I've heard "lose the cc3d" a million times lol i will switch to a naze when I've got some extra cash, but in the mean time i know this cc3d is fine because it came off my old 250 which was dialed in perfectly. Thanks in advance!
