I have mine on a plate that is actually mounted into the motor mount (tekno mount) this works awesome, but would be harder to do w/ the stock losi conversion.
She has a very nice balance, I love the way it feels on the track and in the air. I'm a touch heavy in the rear due to my aluminum wing mount, but it's bearly noticable. I may actually swap the plastics back in, it just happened when I originally got my roller the aluminum parts were already installed and when I rebuilt I just left it. The aluminum takes quite a beating, thats the only reason I left it.
