Hobbywing XeRun V10 G4R motors

Hobbywing has released the latest development of its popular XeRun V10 motor with the new G4R 13.5/17.5 which is available in both a Standard and ROAR version.  Featuring a new stator, rotor and sensor assembly improves the G4R spec motor’s performance and power dramatically.  Compared to the G4, the G4R shows confirmed improvements in overall speed by up to 5% while the output power is increased by nearly 4%.  The G4R 13.5 shows 7% more speed, and 9% more power, under the same test loads as popular non Hobbywing motors.  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 3% lower than that of G4.
