If using the old motors ignore this step
The motors will not mount straight away to the old main chassis.
The new motors shaft sticks out more than the old ones and doesn't line up with the old chassis part.
The new motor mounts should attach to the old holes but only in two places with the gap in the circle pointing downwards on the port and starboard motors.
Once attached you will notice if you try to put the motor in the mount it will not line up with the existing hole for the shaft.
This needs to be drilled out in order to mount the motor
