10x45 Propellor, 3Cell, Benchmark

The second test is with a hobbyking Slow Fly Electric Prop 1045SF .
In combination with a 3Cell lipo battery this prop is oversized. That means that it is not safe to use this prop at maximum power. It could cause overheating and damage the motor. But I use this prop in a multirotor and this multirotor will hover at 40-50 % power. So I can use this propellor safely.



The difference between puller and pusher configuration is again ~5% .
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).

Although I would espect this prop to be more efficient then a smaler 9 inch prop this 10 inch prop is less efficient. At 350 gr thrust the motor is significantly warmer then with a 9 inch prop. It's not to hot but you can clearly feel the difference.
