I am running a 1.08 FSR in a Great Planes U-Can-Do 60. It has unlimited verticle and rockets out of a hover, if it gets hairy. You MUST practice throttle management with this set up, but the 1.08 isn't that much more than a good .91. The 1.08 swings a 15X6 prop with great authority. I think Tower is selling the UCD for about $179.00. On low rates and low throttle it flies like a slow pattern plane, kick up the rate (use plenty of expo.) and you'll have a ball. This is a great, steady, stable airplane that can outfly a stick any day. Give it a try, you won't regret it.
