RE: UCD 60 knife edge advice please!
I had 12% up elevator mixed with rudder.
Hated the plane. Only thing it did good was hover, and I had already mastered that long before I even got the U-Can't-Do 60.
I had my balance pretty far back. Saito 91- and then switched to a TT120. I had high torque digital coreless servos on it. So, I know the problems weren't just sloppy control surfaces from weak servos.
I tried engine thrust correction, wind incidence corrections, and balance corrections. Spent more time F***ing with it than actually flying it.
Ended up throwing it in the garbage can. POS I can't believe they are so popular. If you got one and like it-- then I'm glad for ya. Enjoy the hobby however you like. I should have smashed mine and threw it in the can months before I actually did. Nothing but a frustrating POS.
