Standard version/ROAR version 13.5T/17.5T
New Stator, Rotor, and Sensor
Assembly improves the G4R spec
motors overall performance and
power dramatically.
  • Faster and more powerful.
    The G4R platform shows confirmed improvements in
    overall speed and power output by up to

  • Comparing it with V10 G4 motor series:
    The output power
    is increased by nearly

The new Hobbywing G4R 13.5T shows 7% more speed, and 9%more power,
under the same test loads, than popular non Hobbywing motors.
Low internal resistance,
high efficiency
The new G4R stator and winding design reduces the overall internal resistance,
while maintaining the requirements for sanctioning spec class rules.
The improved motor efficiency reduces the temperature rise to
keep internal resistance numbers consistent.
The internal resistance is about lower than that of G4
Good heat
dissipation with low
temperature rise
The motor adopts an open core can,
and uses an all new Rotor. This
allow the heat generated by the
stator to be directly cooled by
airflow. The can and rotor design
allows air flow throug the motor to
maximize cooling.
  Warning:   The rotor heat dissipation is a patent design.
  standard version   X   ROAR version  
Dual version selection
The standard version is designed according to IFMAR/EFRA rules.
and the ROAR version is designed according to ROAR rules.
Note: The standard version is in the EFRA list, and the IFMAR list is pending certification;
the ROAR version is in the ROAR certification list,
and the specific version used is subject to the rules announced by the competition.
The ROAR version uses thermally
conductive winding epoxy to fill the
coil caps and increase overall heat
dissipation. Lower temperature rise
and improved overall performance.

The temperature of
the ROAR version is about
lower for the same input power.
Updated nylon mixed shims provide ultra quiet motor
operation and provide long lasting consistency.
The wear resistance of the gasket is increased by
approximately
Wear-resistant silent gasket
G4R motor windings use the highest temperature rated wiring to date. This
allows further resistance to heat, while increasing the overall motor efficiency.
Compared to other brands, temperature resistance is up to higher.
Resistance to high temperature damage means the motor can be pushed to
it's limits and come back for more.
220℃ high temperature
resistant enameled wire
The G4R features dual sensor ports providing racers with options for sensor
wire routing. The unused port is protected by the included silicon port plug.
Dual sensor port
The motor comes standard with a rotor (PN 30820450). It is suitable for most Blinky competition applications; the optional rotor (PN 30820407) has a stronger magnetized rotor and is suitable for medium and large track (Blinky) competitions, or high traction tracks application.
Optional rotor available
Easy Maintenance
The G4R uses a sleek and simple modular design. This
makes regular service and cleaning simple and direct.
Cleaner motors last longer and run more efficiently.
Industry-leading
materials and excellent
product design
The copper on the motor is thicker to ensure lower internal
resistance and greater heat capacity of the motor.
The large opening heat dissipation structure at the tail of the motor
provides excellent heat dissipation effect for the sensor components.
