Thanks for such a great design, Peter. It was only my second wood "plan-build" (foamies don't count!) since 1983, the first being a Sharkface. It was originally powered by a Saito 45, which was ample, but after seven flights and some reliability issues, the Saito was replaced by an O.S. 52 Surpass. Way too much power, it has the model off the ground before the throttle's halfway forward, but she takes a good chucking about and lands with the motor running. The maiden was a week past Friday, and she's already had fifteen flights!
