RE: U-can-do 46 or 60
2 years ago at the filed, a club member did the maiden flight on his ucando 60 with a saito 100 and tower digital servos. It flew great and it hovered real nice he said.
A little coupling during knife edge but that can be sorted out real easy.
Looked like a great plane to me, if they were available as kits I`d definately buy one.
