Few questions:
1. Anyone using a Saito 91 or another 91 size four stroke in the UCD 46?
2. Can it do knife edge spins?
3. Is there any coupling in knife edge?
1: I am using a Saito .91. Awesome power. I am only at 550 feet elevation though. If you're signifcantly higher, I say put a 1.00 on it.
2: Yes. With a lot of elevator throw and full throttle, mine knife-edge spins so fast it's a blur.
3: Yes, a lot. Pitches to the canopy and rolls opposite rudder input. I have mixed some of it out with my radio to where it isn't too bad.
