the engin sits real high, but with the ansmann i can get the truggy to sit low enough to get the starter wheel to hit the flywheel, but i had to take a fair chunk out of the chassis to make enough room so the starter wheel didn't rub.

the 8ight T RTR engine mount sit's high so the mach's can fit in the 8ight, i was told over and over it was impossible to make it bump start without the race roller engine mount, but it works..
