11x47 Propellor, 3Cell, Benchmark

Next prop is a 11 inch Hobbyking Slow Fly Electric Prop 11X4.7

Like the 10 inch props this 11 inch propellor is also oversized in combination with this motor on a 3 cell lipo. So it is not safe to use this prop at maximum power. For this prop I have the same motor temperature remark as for the 10 inch Slow Fly prop. It looks like the 11 inch prop is more efficient then the 9 inch prop at the thrust  I need to hover in my current Y6 copter project.

The difference between puller and pusher configuration is ~4% .

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).
