I have ALWAYS used APC props on all my R/C planes; pattern, pylon, and sport as I'm never willing to give up ANY performance. They are MUCH stronger than wood as well....a minor touch to our grass field with an APC equals a grass/dirt mark on the prop, with a zinger it is a busted prop.

I DESPISE wood props for that reason.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
