Hobbywing EZRUN Combo MAX8 G2 and 4278/ 2250kV G2 Motor HW38010405

Introducing the Hobbywing Max8 and 4278 brushless combo.

The Max8 G2 ESC is the most sought-after ESC on the market. It’s dynamic and dominant specifications meets the needs of power-hungry users. It has a strong output power with excellent linearity at low speed and is operating on full-sensored mode.

A perfect combination EzRun 4268/4278 G2 Motor
Perfect compatibility when used with EzRzun 4268/4278 G2 motors. Ensures motor is protected against overheating to avoid damage.

Applicable to All Weather Track Conditions
The IP-67 system guarantees excellent waterproofing and dustproofing protection. The whole power system is able to drive on a variety of surfaces including mud, sandy, icy, snowy and water without damaging the power unit.

Super Built-in BEC
The ESC has a built-in BEC which can support a maximum output current of up to 15A and the output voltages are switchable between 6V, 7.4V and 8.4V. This ensures that the ESC is able to support the demanding high-torque servos in the market.

Built-in Big Capacitor
The ESC has three built-in 680uF capacitors, which increases the performance by 74% (870uF) compared to the MAX8 ESC. The ultra-large capacitors built onto the ESC also ensures users do not need to install external capacitors on for most vehicles.

New sensored cable interface
The Max8 G2 ESC is equipped with a new type of sensored cable interface. It is high recommended to use the motors from Hobbywing as the waterproof protection level is at the highest level (IP67). Note:
This ESC also supports wires with the standard interfaces on the market.
