I went with some larger dubro wheels. I fixed the tip over problem with the ground handling by shimming the trailing edge side of the retract gear. Worked pretty good. Something to look out for. I was flying yesterday and when I landed the whole right gear came out of the retract housing. What it ended up being is there is a retention screw for the pivot pin. luckily I was already on the ground when it came and was able to find the pin. The Plane flies great and the landing arent too bad. The vertical on this plane is pretty nice too. When I pull up the plane doesnt even seem to slow down. I really like this plane.
