I'm in the process of building my sc10 4x4 and noticed that my orion 550 doesn't sit flat on the chassis. When I position it so that it's flat against the motor plate, that end of the motor is not resting on the chassis. It's not as big as the novak ballistic 550 that requires more modification (dremmeling and opening up the center chassis) to get the motor in place and sit flat.

However, does everyone who has a 550 motor have to do some dremmeling to the chassis to have the motor sit flat?

Sorry if this is a basic question. I also didn't see it posted on my search of this thread.
