After the continued success of the first generation 40mm Hollow Evolution Cooling System, we are excited to release the all new 30mm Hollow Evolution Cooling System.
This new 30mm weighs in at 13g+ and complies with ROAR regulations. It’s static wind pressure reaching 10g+ to provide more cooling and giving the motor lower IR during the race compared to the traditional computer style fan.
Keep your Motor cool with the hollow evolution cooling system!
