Ok...here's another to help you out Joe...
Mounting and de-mounting the motor is a bitch on the FT-TC4. Plus when using a ball hex driver the motor screw always seems to fall off the bit RIGHT BEFORE you get those first couple of turns into the motor.
Since it's 2.5mm for the motor screws...when mounting, hold the motor and use a STRAIGHT 2.5mm wrench initially. You can get the first few turns in by holding the motor at an angle, once both screws are in by a few turns, take your 2.5mm ball-head driver and finish the job.
Hope you kinda got what I meant there...
