I just installed my M-16 in my 4-tec. Can't wait to run it. I have to modify the upper deck chassis to allow the carb to fit. The angle is a little bit off compared to the stock motor. Plus I broke the steering bellcrank posts off..lol Does anyone know if the carbon fiber upper deck is worth the money? Also, can someone tell me how to post pics correctly? Thanks and I will let you all know how it goes.
