Hobbywing V10 G3 titanium-bonded rotors
Hobbywing have introduced two new titanium-bonded rotors for the V10 G3 series of brushless motors. The characteristic of the rotors will provide a smoother pickup acceleration without sacrificing top speed. This will help to tune motors especially to lower grip asphalt and carpet conditions as it aids car control out of tight corners. Available variants are a 5-12.5 and 5-12.3 that come individually marked for easy identification.
