Happy Birthday Dave.

I have to admit that the stock 400 motor on my su-27 is around here somewhere, but the plane has a turnigy 1900 kv outrunner turning a 7x6 apc prop. It sounds like a gasser in the air. When it's right it's a hoot, but not exacyly a queit flyer. I've been told that the roar is the product of the tips of the prop breaking the speed of sound(?). I don't take it out much.
