RE: U-Can-Do 60 Engine opinion
Had a UCD 60 with a Saito 125 swinging a apc 17x4w, pulled very well from a hover, flew nice and easy and slowed well with that wide prop. It's been a while but I may have changed to a apc 16x4w at some point..... still have both the props.
I know I flew the 16x4 on a Fusion.
