Well I"m not RCKen or Minnflyer, but most of the people I talk to like APC props; it seems to be the standard for the plastic props. I haven't used one yet, just because I bought a bunch of the Master Airscrews (because I thought they look better
) and still have a lot left.
Wood props wont' take a prop strike as well, but are actually better performers as they don't flex like the plastic props do.
