FAQ

What is included in the Hobbywing EZRUN Mini28 3500kV combo? The combo includes an EZRUN Mini28 30A electronic speed controller, an EZRUN 1626SD 3500kV sensored brushless motor and supporting installation accessories. Product instructions are supplied with the system.

Is this combo suitable for 1/28 scale RC cars? Yes. The system is specifically designed for 1/28 scale miniature RC racing cars. Hobbywing also lists the Mini28 ESC for compatible 1/27 scale vehicles. Check chassis clearance, motor mount, gearing and electronics compatibility before installation.

Can I use this system in a Mini-Z or 1/28 drift car? It may suit compatible miniature RC racing and drift builds. However, individual Mini-Z and aftermarket chassis have different motor mounting, electronics and drivetrain arrangements. Installation is not guaranteed to be plug-and-play.

What battery does the Hobbywing Mini28 combo require? The ESC and included 3500kV motor are designed for a compatible 2S LiPo system. Use the appropriate battery connector and ensure the battery fits your chassis.

What does the 3500kV motor rating mean? The 3500kV rating describes the motor's approximate no-load speed constant in RPM per volt. It does not represent battery voltage or motor power output. Actual vehicle speed depends on gearing, load, battery condition and ESC settings.

Does the ESC support sensored brushless operation? Yes. The Mini28 ESC supports sensored and sensorless brushless motors. For full sensored operation, connect the motor phases in the correct order and use the appropriate sensor connection.

Does the ESC support boost and turbo timing? Yes. The Mini28 provides programmable electronic boost and turbo timing. These settings can improve performance but also increase motor and ESC temperatures, so they should be adjusted carefully.

Can I program the Mini28 ESC using Bluetooth? Yes, with a separately purchased compatible Hobbywing OTA Programmer. The OTA module enables supported settings and firmware operations through the Hobbywing mobile application. Bluetooth is not built directly into the ESC.

Which Hobbywing programming box works with the Mini28? Hobbywing lists compatible LCD programming devices, including its LCD G2 and LCD Pro options, as well as the OTA Programmer. The basic LED programming box is not supported. Confirm current accessory compatibility before purchase.

Does the Mini28 ESC have a built-in BEC? Yes. It features a switch-mode BEC with selectable 6V or 7.4V output and a maximum current rating of 3.5A. The selected voltage must be suitable for the receiver and steering servo.

What size pinion gear does the motor use? Hobbywing's published specifications list a nominal 2mm shaft, although one retailer reports 1.8mm. Measure the shaft or confirm the exact pinion fit before purchasing a replacement gear.

Is the ESC waterproof? No. Hobbywing specifies the EZRUN Mini28 ESC as non-waterproof. Protect it from moisture, water and conductive debris.

Does the combo include a battery, receiver or transmitter? No. This is a brushless power system combination. A compatible battery, radio system, steering servo and vehicle chassis are required separately.
