  • Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

About this product

The Xerun V10 G4R motor from Hobbywing ensures outstanding performance on the track. With up to 7% more speed and 9% higher performance, it stands out clearly from comparable motors that are being used in similar situations. Even compared to the G4 predecessor, the improvement in performance is still an increase of 4%, offering an excitingly powerful driving experience in every 1/10 stock race.

The G4R motor manages to dissipate its heat through an optimised airflow thanks to the exposed core and the completely new rotor design. For this purpose, the outer diameter and total area of the G4 predecessor were increased by more than a quarter in order to effectively cool the engine and quickly dissipate the heat to the outside. And even if it does get a little hotter: the wiring inside the motor for example can withstand temperatures of up to 220°C. And the newly installed nylon shims also reduce the overall noise level and are particularly wear-resistant components.
You are also free to install the motor according to Your own needs. For example, there are two sensor connections to make the cable routing as space-saving as possible. if You place even more value on personalisation, you can use the optional rotor to make the motor ready for particularly demanding competitions.

Features

  • 9% more power and 7% more speed than comparable engines
