Looking to purchase a U-CanDo What's the better flyer, the larger model equipped with a YS91 or the smaller version with a 46ax. Which one has better flight characteristics?[>:]

I have the 40 size with a Saito 100 and it's a lot of fun. I'm not a skilled 3d pilot but I'm having a lot of fun with it. Its overpowered so I have to be careful not to tear off the tail or ??? going to fast. The power is neat and gives unlimited vertical. Either choice should work.
K.O.

I bought the 46 size with an OS 91 four stroke. I bought the smaller one mostly because of the fewwer $$ needed because a smaller engine can be used. Also from what I have read the larger model has bad pitch coupling in knife edge while the smaller model still does it but apparently no where near as much.

Fazer,
I have both. Saito 82 on the .46 and Saito 100 on the 60. I like both planes. The 46 is my fourth. I keep crashing mostly I think because I try things with this plane that I wouldn't do with my others. I think both planes fly, fun. But I think the 46 is a better flyer. It seems to do almost anything I try even the inverted flat spin landings. Unfortuneatly, after one of those landings you put it in a bag for spare parts.
Thanks,
Barry
