Tarmo3 Mostly metal drivetrain

thingiverse

I Upgraded the Drivetrain of My Tarmo3 Mostly to Metal for Better Performance and Durability. I Made the Upgrade Primarily so I Can Ride in Mud or on Rocky Terrain without Having to Repair It Every 30 Seconds. Also, a Bigger Motor Produces Too Much Torque for the Plastic Diff to Handle. To Further Enhance the Build's Reliability, I Added a Cover for the Servo That Helps Keep It in Place and Prevents Staggering. Required Components for This Upgrade Are as Follows: - 2x Diff HSP 02024; Note that You May Need to Modify These Parts Depending on the Seller, So Make Sure to Cut Out the Small Wall Between Bearings and Enlarge the Hole Slightly with a File.
