motor mount

Just received my BL 9XL motor and Im concerned about the weight shift. If I use the stock motor mount the truck is very much unbalanced depending which side the motor is on. Doesnt this cause problems when jumping? Im using a FLM Chassis and was wondering if there is a motor mount that will center the motor. I looked at the Gorilla Max mount, but is says its for the X-Brace Chassis only.
