Overview
The Rocket-RC Gecko 3660 Fusion is an integrated 2-in-1 FOC motor and 40A ESC system for 1/10 RC crawler cars. Its compact 36 x 56 mm design combines the motor and speed controller in one unit to help simplify chassis wiring and cable routing. The 1800KV system uses FOC drive with a built-in magnetic encoder for rotor-position detection and controlled low-speed operation.
Key Features
- Integrated 3660 motor and 40A ESC design for 1/10 crawler applications.
- IP67-rated waterproof and dustproof protection.
- Three drive modes: forward with brake, forward/reverse with brake, and forward/reverse.
- Selectable BEC output for compatible RC electronics.
- Built-in LED power switch provides real-time motor-status and fault-code indication.
- ESC protection functions include over-temperature, overload, overcurrent, low-voltage, and throttle-signal-loss protection.
- Supports an LED digital programming card for ESC parameter adjustment. A programming card is available as a selectable option.
- Features a high-toughness stainless-steel shaft and 220 C high-temperature-resistant enameled wire.

Details


IP67-rated protection helps the integrated system handle wet, dusty crawler environments.

Choose forward with brake, forward/reverse with brake, or forward/reverse operation to suit the terrain.

An optional LED programming card supports convenient ESC parameter adjustments.

FOC drive and magnetic rotor-position detection support controlled low-speed crawler operation.



Selectable 6.0V, 7.4V, and 8.4V BEC output supports compatible RC electronics, while the LED switch indicates status and fault codes.


The compact 36 × 56 mm unit uses 175 mm wires and is specified for 2–3S LiPo or 4-cell NiMH batteries.
