I'll just look around for a better place to fly. There is a club in Hurley which is about 40 miles or so from my house. That would be a pain in the tail to go that far everytime I want to fly. I should be able to find a place with a dirt road to land on. If I did decide to go with larger tires (not sure what size is on mine now) how will that affect the flying of the aircraft? I suppose it would only slow it down somewhat and I would need to recheck the CG once I had them installed. It really shouldn't have much effect on the CG though, just a little more weight.
