I have my YS63 in a Sig Kadet Seniorita 3 channel.... OK, it has been modified a bit, but it still looks like a Kadet from 10 feet away. Plane is at 3.75 lbs, 1/3 chord full span ailerons, enlarged elevator rudder. Talk about jaws dropping... I just takeoff and putter around like it is a Kadet, no more than two clicks of throttle, user rudder only for turns, etc. Then after a few minutes of that I bring her in slow and low for a landing, but instead I pull a wall center runway, hover for a sec at idle like I screwed up and stalled on landing... but then the surprise... I open that YS up, it roars to life belching out a ton of smoke and launches the Kadet to the moon... he he he... man I have fun doing that. Gets the folk in the peanut gallery to choke on their own spit.
