Barry, sorry about your loss.

Ok, I know that this has been discussed several times, and I'm sorry for bringing it up again. It is difficult to sift through 73 pages! So, I have the 50 SX on my UCD, and as impressive as its power output is, I have found it to be totally underpowered for what this airplane was intended to do. With the type of maneuvers the UCD is capable of, and the altitude I'd like to perform them at, I'm starting to think the more power the better. My question becomes this: How big should I go? I have an opportunity to pick up a Saito 91 at a slight discount and I'm close to doing it. I'm wondering though If I'd be better off going with the 82 (or something even smaller). For the price difference that seems like a lesser buy, but I'm not looking to go overboard with power. Right now I'm leaning toward the Saito 91, but I'd love to hear about some alternatives anyone can recommend.

Thanks for the input,
Rob
