So, as a newbie I had reported that I flew my Phantom in a wide area and then the quadcopter flew out of control clipping bunch of pine trees and then a crash onto the grassy area beneath the tree. C-clamp from one of the motors was found in the motor housing. So, I believe that was the cause of the runaway. I have upgraded with T-Motors Antigravity just as an upgrade and not merely to replace that one motor with piss poor bearings and C-clamps (some call it "e" clamps). Beautiful thing - the T-Motors! My Phantom's right red light motor still is not rotating normally. Hesitates. Could the ESC "red" board gotten fried from the original stock motor jamming and backflow resistance created to the board? I would hate to purchase a new ESC red board if that's not the issue. And if it is the issue, is there a way to correct/fix it? Programmable? I have no clue how to use the NAZA PC tool. Any advice is appreciated. Thanks.
