Nick.CNC Mid Motor Conversion for Traxxas Bandit, Rustler, and Slash

The Nick.CNC mid motor conversion allows you to convert your Traxxas 2wd vehicle to a modern mid motor layout for better handling. All the files needed to print and CNC cut your parts are included. Don't have a CNC? You can send the step files to a cutting service like sendcutsend and they'll cut the parts for you, but you'll still need to countersink the holes.

Important Information

• Two different transmission configurations available:
  • Standup Transmission - better suited for low grip conditions. Files specific to the standup configuration are indicated with a “SU” prefix.
  • Laydown Transmission - better suited for high grip conditions. Files specific to the laydown configuration are indicated with a “LD” prefix.
• Suggested thickness for CNC cut parts
  • Chassis 2.5mm
  • Shock Towers 3m to 4mm
  • Motor Plates 2mm to 2.5mm
• All printed parts are designed to work with my chassis and will not work with the stock chassis or any aftermarket chassis
• Transmission cases are designed to use the magnum 272 internals. Magnum 272R internals, including the sealed gear diff, will not work.
• Nitro Rustler rear arm mounts are required
• Adjustable turnbuckles are required
• Designed to use the Team Associated B6 series rear wing mount
• The transmission cases have reliefs designed into all bearing and axle recesses. Use your slicer to paint the Z-seam onto these reliefs to prevent z-seam blobs from affecting bearing fitment.
• All printed parts have survived multiple track days without breaking even when printed with basic PLA
• The battery posts are sized to work with the Protek LCG batteries I use. You may need to scale the height of the post up or down depending on how tall your battery pack is.

Disclaimer

All files are sized for the screws/bearings/fitments/clearances/etc. to work on my machine with my filament. You may need to tweak your extrusion multiplier or even scale the parts in your slicer to account for the specifics of your machine and filament.
