The kits I received from my buddy contained a bag of 10 wood props to each engine. I ended up with 3 bags of props, 2 bags being maple and 1 being beech. I use my airplane engines primarily for Airboats so I have not used any of the wood props on them. Wood props + water = bad things happening. I never even tried one on the test stand. I went right to Nylon and Nylon composites.

I am going to build a plane, so the purpose of my engines will shift somewhat to double duty. Air boats, and Air planes. (I like to not limit my options with RCing stuff. I'd RC my lawnmower so I could mow from my living room if I could afford the traction motors and servos..

The idea of a line of soldiers firing at one of those beasts using tracer rounds would be a sight to be seen.

There are videos on YouTube of these airplanes being flown by civilians. I heard awhile back since the program was discontinued, that some of these airplane kits are still around and had found their way out of the military and into civilian hands. I think my buddy that gave me the engines has 2 or 3 of these foam airframes laying around. I should see if he still has them when he returns from his Kuwait deployment in June 2012.
