Not only the lenght of the motor but also the shape.
The LRP X11 motors fit perfectly without the use of a dremel.
It is because of the backside shape of the motor.
If it is tapered it fits ok,if it is like the Tekin or GM motors with a 90 degrees backside,you have to dremel a bit on the side belt tensioner and the left bulkhead to get anough room to play with the gears.
