Yes that's why I was a bit iffy with the Mez 23x8 maybe might have to try going up in the diameter down in the pitch as you said but might give the Mez a bit more of a trial as it was only my first flight with the plane, haven't had that much experience with 50ccHope the weather is ok this w/end so I can give it a real going over, on the maiden the wind picked right up just as I had got the plane ready to fly no way was I going to pack it all up and go home well I will see how things go this w/end.
