RE: U-can-do 60 questions
Should be OK - make sure you have a fine prop though. these things don't like to go too fast. I like the APC W series in a 4" pitch for them (Not sure what diameter will suit that engine). My UCD 60/90's are one of my favourite lazy day fliers. I tend to do stupid things with them though (Like Dumb thumbing) but I always like to have one in the hanger.
