You guys really shouldnt open your mouth if you dont know what your talking about, just makes you look more stupid. My first nitro rc was a CEN Fun Factor. I could easilly get 45-50mph out of that truck. It lasted me 2 years without any problems. I rebuilt the engine after 7 gallons due to performance loss and I just recently sold it. It was an awsome truck for me. It was also National Champion in the .16 1/10 scale class trucks. So if you guys thing CEN products are crap think again. The new CEN products could sweap any stock trucks such as the revo, t-maxx, savage. I just bought the T-Maxx about 4 weeks ago, and no way does this t-maxx have the speed my cen had.
