The U Can Do is an awesome plane. I am flying the 46 size with a Saito 82 and it rocks. The thing glides better than my Superstar trainer. Don't know but I bet the 91 is enough engine for the 90 sized one.

The plane at low rates is very docile and anyone could land the thing. High rates it will do amazing things.

Note the huge grin each time I fly...
