I can tell you the engine choice is perfect. This plane is reported to fly very well. Only drawback of this plane is handling in windy conditions, but on calm days, it should be a blast. One of our club members bought one when they first came out and told us that if he ever crashed it, he would run to the hobby shop to buy another. He had an OS .91 in his, and said it was a perfect powerplant for the plane. You will probably have to add quite a bit of lead to the firewall for balance. I always say if you like it, buy it now, because if you wait, the plane will be discontinued before you know it. It seems I read a review of this ARF in one of the mags, and they had nothing bad to say about it. I think the reviewer used a tailwheel instead of the wooden skid since he flew off of pavement.
