Ok now I got a working flying umbrella going, now to specifics.....First off is which motor to use, or does it even matter....I like the norvel 25 for my PBF so I think I may buy another one of them to have. I'm going to also take the coroplast idea from the pbf and make a profile fuse out of it with one hell of a rudder. Does weight make a difference? CG on the umbrella? really all I need is a rudder servo and a throttle servo right? the elevator is built into the lift of the motor and umbrella combo. When it DOES fly and I add full throttle will the fuse be ahead of the umbrella or will the umbrella shaft stay perpendicular to the ground? Adding to that question is a full throttle loop possible?
