I agree, I even added a header tank and put better tubing in the tank due to flame outs. I never had problems with the frame bolts though I hear a few people do. I changed all the frame and t/r case phillips head bolts out to socket head bolts too. I use carbon main and tail blades and went to carbon fins too. I also wasn't happy with the power to weight so I dropped in a .91...But all of these are afterthe fact items.....
