RE: Looking for a decent engine
Flyboy Dave,
When you say "MAS toothpick prop" I assume you mean a Master Airscrew.
Do NOT spin a Master Airscrew over 16,000 rpm.
Do NOT cut it down.
I learned both of these lessons the hard way. It almost cost me my life. The material they use is crap. Get an APC with the thick "D-1" hub, or better yet, buy a good wood propeller and cut it down until you get the rpms you need.
Oh, and never run an engine unless you are wearing safety glasses or sunglasses made of at least .060" polycarbonate. A propeller fragment travels at the same speed as a bullet. Polycarbonate will absorb the impact without shattering.
Just a word to the wise.
