Following my previous models of flipped-CIM and flipped-MiniCIM gearboxes, I made a flipped NEO gearbox designed to interface with the AM14U-style Kit of Parts chassis. We don’t have the data yet as to how well these motors actually work in drivetrain applications, but I can say that their small form factor makes them package beautifully.
• Extends 2.3" into the chassis (compared to 3.6" for a NEO with the standard TB Mini gearbox, can be lowered to 1.8" by removing the encoder and trimming the motor shafts)
• Weighs 3.24 lbs (1.36 lbs without motors, compared to 1.95 lbs TB Mini)
• 7.67:1 reduction for 16 ft/s adj with the default 6" wheel (or 10.6 ft/s adj with a 4" wheel)
• 2" clearance from the frame perimeter to the motor
