I have been testing one as well and all I can say is...incredible!! I raced the RC Pro Series with a mod .21 in my MGT and this motor smokes it. Surprisingly it is very drivable and easy to tune (2 needle carb). After running hard for about 15min, it will just sit there and purrrr!

I won the divsional title just 5 points shy of a perfect. If I would of had this engine, I would of had a perfect!

BTW...I could actually yank the front wheels of the ground from a standing start with this engine, and that just doesn't happen with an MGT!
