Repeat Robotics Mini Pro 1106 Brushless Gearmotor
Pro-grade drive hardware for serious competition
The Repeat Robotics Mini Pro 1106 is designed for antweight builders who want premium mechanical hardware in a compact brushless drivetrain. It combines a custom 3500KV 1106 brushless motor with a 22.6:1 all-metal planetary gearbox and upgrades the output stage with dual ball bearings, a 4mm hardened steel billet shaft, machined planet gears, and four final-stage planet gears.
Why choose the Mini Pro?
The standard Repeat Mini remains an excellent high-performance drive motor. The Mini Pro is the step-up choice for builders who place an especially high value on drivetrain durability. In combat robotics, a drive motor problem can end a match very quickly. Spending a few extra dollars on premium drivetrain components can be an easy decision when reliability is one of your design priorities.
Premium planetary gearbox construction
The Mini Pro uses a 16mm-diameter, 22.6:1 all-metal planetary gearbox. Its final stage uses four planet gears instead of the standard three, and the planet gears are machined for added durability. Dual ball bearings support the output shaft, while the 4mm hardened steel billet shaft provides a robust interface for your wheels and hubs.
Flexible mounting options
A four-lobed mounting pattern on the face makes the Mini Pro easy to clamp mount. Builders who prefer face mounting can use the four M2 tapped holes arranged on a 14mm circle.
Brushless power for antweights
The custom 3500KV 1106 brushless motor is rated for 2S-4S LiPo operation. Repeat Robotics notes that the current MK4.1 motor provides about 20% more torque than the prior MK4 motor. As with any brushless drive system, use a compatible brushless ESC configured for bidirectional operation.
ESC and electronics
ItGresa offers the broadest selection of ESCs of all types, including Repeat Robotics’ AM32 brushless ESCs. Repeat offers both single AM32 drive ESCs and the Dual AM32 ESC. You can also browse our ESC selection for additional options. Always match the ESC to your battery voltage, motor configuration, and drivetrain requirements.
Standard Mini or Mini Pro?
Both are purpose-built brushless drive motors for antweight combat robotics. Choose the standard Mini MK4.1 when you want an excellent balance of performance, size, weight, and price. Choose the Mini Pro when premium drivetrain construction and added mechanical robustness are worth a little extra weight and cost for your design.

Frequently Asked Questions
How is the Mini Pro different from the standard Repeat Mini?
Both are high-performance brushless drive motors designed for antweight combat robotics. The Mini Pro adds premium mechanical features including dual output bearings, a 4mm hardened steel billet shaft, four final-stage planet gears, machined planet gears, and a four-lobed mounting face. The standard Mini is an excellent general-purpose choice; the Mini Pro is aimed at builders who want to invest a little more in drivetrain robustness for demanding competition.
Why spend more on the Mini Pro?
Drive reliability matters in combat robotics. If a drive motor goes down, even an otherwise healthy robot can quickly lose mobility and the match. For builders competing at a high level, spending a few extra dollars on premium drivetrain construction can be inexpensive insurance against a match-ending mechanical problem.
What ESC should I use with the Mini Pro 1106?
The Mini Pro requires a brushless ESC configured for bidirectional drive operation. ItGresa offers the broadest selection of ESCs of all types, including Repeat Robotics’ AM32 brushless ESCs. We offer both the Repeat Robotics AM32 ESC, for a two-wheel-drive robot you’ll need two single ESCs; or one Repeat Robotics Dual AM32 ESC to control both motors. You can also browse all ESCs at ItGresa. Always verify that your ESC supports your battery voltage and motor configuration.
What battery voltage can I use?
Repeat Robotics rates the Mini Pro 1106 for 2S-4S LiPo operation. Make sure the ESC and the rest of your drivetrain electronics are also compatible with the battery voltage you choose.
What does the four-lobed mounting face do?
The four-lobed pattern gives a clamp mount more surface to capture and makes clamp mounting straightforward. If you prefer face mounting, the gearbox also has four M2 tapped holes arranged on a 14mm circle.
Why does the Mini Pro use four planet gears in the final stage?
The final stage uses four planet gears rather than the standard three, providing another point of load distribution in the drivetrain. Repeat Robotics also specifies machined planet gears for added durability.
Is this motor only for experienced builders?
No. The Mini Pro is a premium component, not an experts-only component. Any builder can use it with a properly matched brushless ESC, battery, wheels, hubs, and mounting system. Its appeal is simply strongest for builders who value premium drivetrain hardware and competitive reliability.
Does the Mini Pro include an ESC?
No. The Mini Pro gearmotor is sold individually. A compatible brushless drive ESC is required.
