Blackie,
I just finished a Hangar 9 Cap 232 with a BME 102, thats a 6.2 cubic inch engine with something like 10 H.P., it spins a 28 x 10 carbon fiber prop @ 6250 RPM on the ground with only 4-5 tanks of gas through it. It will get more powerful as it breaks in more. Takes like 15 gallons of gas to break in all the way.
I have been VERY scared of this prop, and I don't mind saying so. A healthy fear brings on a healthy respect and attention to details. At this RPM and power this thing could and would completely take your hand, arm or leg clean off. Fingers? HA! like a hot knife through warm butter. Be careful and NEVER, EVER fly alone or start any engine no matter what size without a helper or in my case two!
