Introduction / Backround information
I started with a H-Quad using DT750 and was not really impressed (not the best ones for doing aerial photography). Then I switched from my H-Quad to a F450 with the original DJI 2212 920 KV motors spinning 10" props. But the problem was as I added a GoPro, FPV system and a BL gimbal the weight was about 1,7kg. In addition the flighttime went down to about 5 minutes. So I decided to use better motors to increase the flight time!
DJI 2212 920 KV VS SunnySky 2212-13 II 980KV
First test was all about the vibrations of the motors. Here is a short video:
As you can see the SunnySkys perform really well! What is also woth mentioning is that the really low vibrations of the SunnySky motors do not increase as adding throttle or reducing throttle. Looking at the DJI motors we can see that the vibradions increase as reducing throttle. In my case these vibrations (on low throttle) leaded to a unstable flight characteristics when loosing height!
Conclusion
I would highly recommend using this motors as they are:
- Silent
- extremly smooth
- well balanced
- efficient
- cheap (50 bucks for 4 motors)
Moreover they perform really well with 11x5 props! My flight time icnreased to 11 minutes which is really good for a F450 with BL gimbal.
