RE: U-Can-Do 60 Engine opinion
I have a UCD 60 with a OS .91 4s. I have a 14x4w prop on it. Its not speedy but it doesn't need to be, in fact you need to keep your speed down with the UCD. This combiniation does all that I ask it to do. But, I'm not really into the 3D flying. It has good vertical but l wouldn't call it unlimited. Hope this helps.
