APC SF - quite efficient but safe only at lower rpm (65000/prop diam max. = 6500rpm for a 10" prop.

APC E - less efficient at low rpm than the SF, but able to withstand far higher rpms (190,000/prop diam. = 19,000rpm for a 10" prop).

Master Airscrew - standard series are not very efficient - sorry, I have no experience with the new "electric only" MA props.

In my experience, for parkflyers, the GWS HD are tough and the most efficient of the lot.

Cheers, Phil
