I just bought 2 t-maxx and one has a m-16 motor from megatech. Seems to run good, but I can't find a hobby store around that carries megatech. I can order online but I think its about 5 years old or more. Anyway if there is something out their that might be better let me know. Not looking for complete horse power, I run for fun. So something mild or should I go back to stock. Thank for the help
