Stefan Kaiser:

Subjective impression of flight

It's really quiet and has enough power. if you move the power stick, then you feel very clearly a difference in the power/speed of the plane. 

Comparison with other propellers

I also tried the APC 21X14E. The only difference was, that with the APC Propeller (about 100gramms) the engine needed 600 mAh less (per flight). 

Other comments

I also tried the 21x14 EL, but I had the impression that with this Propeller, the plane/engine/Propeller made some strange noises in knife-edge Loops  and snap rolls. etc.
