Reverse Thread Brushless Motor 7mm Shaft for RC Drone Quadcopter
Reverse Thread Brushless Motor 7mm Shaft for RC Drone Quadcopter
Reverse Thread Brushless Motor – 7mm Shaft, 4.5mm Shaft Height
Upgrade your RC build with this precision-engineered reverse thread brushless motor. Featuring a concealed motor shaft design that actively protects the shaft from damage, this motor delivers consistent, stable performance across a wide range of RC applications — from quadcopters and multi-rotor drones to fixed-wing model aircraft and light model toys.
Why Choose This Brushless Motor?
- Concealed shaft design — shields the motor shaft during operation and crashes, extending the motor's service life.
- Reverse thread — engineered specifically for counter-rotating propeller positions, ensuring secure propeller retention during flight.
- Included blade fixing cap — keeps your propeller locked in place for safe, reliable flight.
- Stable, efficient performance — smooth power delivery across the 735–746W output range.
- Universal compatibility — suitable for quadcopters, multi-rotor drones, model airplanes, and fixed-wing light model toys.
- Clear wire colour coding — Red (positive power), Black (negative power), Blue (signal line) for fast, error-free installation.

Frequently Asked Questions
Q: What does "reverse thread" mean on this brushless motor?
A: A reverse thread brushless motor uses a counter-clockwise (left-hand) thread on the shaft. This means the propeller nut tightens as the motor spins, preventing the propeller from loosening during flight. These motors are typically used on the counter-rotating arm positions of a quadcopter or multi-rotor drone to balance torque.
Q: Is this brushless motor compatible with my quadcopter or fixed-wing model?
A: This motor is designed for broad compatibility with RC quadcopters, multi-rotor drones, model airplanes, and fixed-wing light model aircraft. Always verify that the motor's shaft diameter (7 mm), mounting hole pattern (23 mm diameter body), and output power range (735–746 W) match your frame and ESC specifications before installation.
Q: What do the wire colours on this brushless motor mean?
A: The colour coding is straightforward — the red wire is the positive power supply, the black wire is the negative power supply, and the blue wire is the signal line that connects to your ESC (Electronic Speed Controller). Always double-check polarity before connecting to your power system.
Q: Does this motor come with a propeller or blade fixing cap?
A: The motor comes with a blade fixing cap included to secure your propeller. A propeller/blade is NOT included and must be purchased separately. Make sure to select a propeller rated for this motor's shaft diameter (7 mm) and power output.
