G'day all,
I've been flying a stock DJI F450, using a 3S 4000mah 30C battery and DJI motors and balanced DJI 10 4.7 props. I'm happy with performance; however, been reading lots of positives regarding the SunnySky motors. So, I ordered the V2216-12 800II some time ago. I recently installed the motors, confirmed the correct rotation for each motor and then installed four new balanced GemFam 10 4.5 props. I reconfirmed correct motor rotation and headed out for a test flight.
My initial stat-up started 3 of the 4 motors. I re-seated the ESC/motor connections for the suspect motor and re-initiated start-up; all four motors started and seemed to respond to the throttle normally. I usually lift off to about five feet, hover, and visually check the airframe and controls; so I did just that. While in hover and no stick movement the F450 stated to rise at a moderate rate to about 15 feet and then decent at the same rate to touch the ground. Attempting to correct with throttle worked, but again, once stabilized at five feet and hands off sticks the same process was repeated. I believe the throttle responded normally when employed and the motors sounded normal to the best of my knowledge.
The SunnySky motors come with extremely long leeds vs the stock DJI motors. I did not shorten the SunnySky leads. So, the only change from the last successful flight(with DJI motors) was the SunnySky motors with the long leads motors. Took the SunnySkys off re-soldered each and every bullet connector reinstalled and did a flight check; same as described above. I did not shorten the leeds.
Replaced the SunnySkys with the original DJI stock motors and all is well again.
So, I'm assuming I screwed up some place; long leads maybe? Is there something more one is suppose to do when changing motors other than just swap out the motors?
Any help is appreciated.
Bob
