Dave,

Thanks. My experience is similar regarding the weight, but experiencing better power output with slight improved RPM, throttle response, and lower noise, which I believe is coming from lighter weight and firmer tip. Good to know that PT has similar performance.

Kevin,

The one additional bit - as the electrics have grown in power (and RPM), APC has started to gradually ''beef'' up the E props (much stiffer torsionally). The 20x13E and 21x14E have been beefed, and they will turn more RPM at reduced noise levels (just as the CF props) compared to the original E prop. Throttle response is certainly better with lighter props, but that isn't really a concern (for me at least) with pattern style flying. I've also run the RASA 20.5x14 CF vs the APC 20.5x14, and they are indistinguishable (on my plane and logger), save the 1 oz weight difference.

Dave,

Nice to know APC is also improving their E props. I have been running the RASA 20.5x14 for a while, like the performance and reduced weight, and the new 21x14 CF prop is another 10g less, at 65g. In addition, it has slight better pull compare to the RASA, not that I need it, but nice to have. I will be testing the same prop in 20.5x14 this weekend to see if it is similar to RASA, since they are the same size.
