With a handy 195mm extension!
Lowering a motor's operating temperature improves efficiency and power output while extending its life. Reedy's HV 30mm Motor Fan comes with a handy 195mm extension. It is simple to install by plugging directly into your receiver where it operates off BEC voltage.
Because it has HV capability, it can also be soldered directly to ESC battery terminals to achieve 24000 RPM and maximum cooling.
Installing in the vehicle is as easy as double-sided tape or fitting it to your favorite fan mount or heat sink.
