20mm shown with Cobri Gearbox

This new brushless motor by Walkera adopts new generation frame design for high efficiency and reliability, no maintenance, and smooth high power performance.  Brushless motors add more power and longer flight times to your electric plane or helicopter. Use our 20mm size as a replacement for your 300-400 size brushed motor.  The included electronic speed controllers (esc) have battery eliminator circuits and also low voltage cut-off so when the battery gets low you can safely control your plane to a landing.  They work with Ni-MH or lithium batteries in the specified voltage range of the esc.  The 20mm will fit in a standard GWS 300-350 gearbox with just a little trimming around the center. Or order with a high performance aluminum Cobri gearbox as shown.

Motor comes with mounting screws and 10T pinion installed.
