XB4 14' shorty pack conversion

[drew_2872]

Can anyone tell me how to turn the 14' model into a shorty pack? I know you turn the center differential 180 degrees to run the motor on the back left. This is all I know what to do. Do I have to trim the plastic chassis any way and do I need other parts. Any info and pictures would be great. Thanks Mike Richmond, Maine, USA

from what I rememeber you need to rotate the diff drill 2-3 holes cut and shave a few bits of the plastic chassis and hope that your shorty is skinny enough not to rub the center diff outdrive.
Make a battery strap as well. There are threads on this and or pics in the the thread as a few have done it

You would also need to flip the diffs as the motor would be running in the opposite direction. Not sure if it's a straight flip in the day. You may need to Dremel the diff cases to suit.

No need to Dremel the diff cases but you do have to clearance the aluminum chassis for the flipped diff bevel gears and for the spur gear.
All easily done with a Dremel.

Might be easier getting the 15 model chassis and bits.

Sell the old one as a roller and buy a '15 is what I would've done.

Buying all the parts separate quickly adds up especially if you want the metal diffs as well
