Thanks Diablo! They are a hoot. I have a Saito 91 on front of the UCan with a 15x4w apc prop. As for the cap, its a OS 50sx pushing a mas 11x6 prop. The ucan will knife edge with little effert on the sticks and will climb up and and travel like clock hands if you stay in it. The cap will knife but no up pull, will just go sideways. I really enjoy both of these planes. I put the cap through its maiden flight today. Did a splendid job!
