The progression from the hammerhead to the tailslide seems logical and reasonable enough. The only real concern I can see (as Hartzell has mentioned) is that with the metal props, there is a problem with rapid gyroscopic precession causing crankshaft cracking. Mind you, snaps have the same problem, stressing the crank, not to mention the rest of the aircraft! Any pilot that snaps to redline G and doesn't think he's hurting his aircraft worse than a straight pull to redline G doesn't understand physics. My personal (and surely heretical) opinion is that snaps are an abuse of the aircraft. Especially at the higher categories, where the judges often have great difficulty telling if a monoplane has snapped or not, one must wonder why someone would desire to deliberately abuse an aircraft so (shrug). -- aboyd at igs.net ATP
