ZomBox - 30lb/12lb 5.8:1 Gearbox & Custom 3520 Motor

Peak Durability for 30lb/12lb Bots! 

ZomBox is an evolution on our previous BoneBox design, now with a kickass motor that has a rear bearing support, all for the price of a standard high-quality outrunner. ZomBox features huge, solid steel 9mm thick planet gears, mod 0.7, a hard coat anodized aluminum ring gear for maximum strength to weight, and massive 17mm ID dual ball bearings. All supporting a billet carrier 1/2" hex 4140 output shaft. All this under 240 grams. Find a more indestructible drive gearbox, we'll wait... 

Designed in collaboration with Brandon from Bone Dead Robotics, this product was essentially born from asking, “What is your dream gearbox for Vorion and Phenomenon?” The result is the most durable drive gearbox on the market for combat.

Replacement motors, planet gears, and output shafts are also for sale!

Replacement motors come with the pinion pressed on.

Motor Specs and ESC Settings

Make sure to match the motor kV to your motor of choice! Our motor is a 650kV option.

Motor specifications will be measured to the best of our ability, but as this is a custom design, there is no listed manufacturer spec. Compare to Badass 3520 650kV. Peak torque will depend on your exact ESC configuration and settings, but should be around 4.5Nm-5Nm (637-708 ozf-in).
