Losi are missing out here. They could quite easily have designed an upgraded motor mount when the car was built and released it at the same time as the truggy to give owners options for motors without having to hack the chassis to bits. The general consensus of opinion is that the chassis is brilliant, just the electrics that arent.
Mind you when you compare the price of the m8t to a merv, it's still a good buy. Its just frustrating having to try different motors and source differnet pinions.
I still want one, but I'll wait a bit to let everybody elses experiment. By the way, rcpitstop will sell a m8t without tx and rx for
