9x47 Propellor, 3Cell, Benchmark

This is my first test with a hobbyking Slow Fly Electric Prop 9047SF. When I test the pull prop and motor the push prop and motor are disconected. and visa versa. As I mentioned earlier my test only handles values at hover. Currently I'm testing to max 400gram thrust, but note that this motor and prop combination will provide much more thrust at max power.




The difference between puller and pusher configuration is ~5% for this setup.

The values in bold at 225 gram thrust is what I need for my current Y6-copter project.
Test is performed with a 12V power supply (= 3Cell lipo battery).
