The problem with Rex is he wants to appear to have knowledge but ive picked up on so many glaring errors in his information thats only serving to confuse people. It appears to me that he needs some more time and experience before he can advise properly.

And if you want any engine Re Pinched you should use Ray A Racing , they are a professional re sizing company.

We have been using him for at least 6 years and every single time we send someone in for service from them , they come back saying the pinch is better than new ! Ray re pinched a Go 25 i modified to use in a Speed Plane for our national titles . we came in 3rd place at 153 MPH . the owner of the plane said the pinch felt and worked so well he is getting all his engines done by them from now on!
