Turnigy

This compact brushless motor has been designed with 250 sized drones and smaller in mind and is an ideal balance of quality, performance and price. Lightweight, tough and compact, the motor is ideally suited to 5" props, 2~4 cell Lipo batteries to give up to 800g of thrust (3.2kg on a quad!) which is definitely not to be sneezed at! The motor is supplied with a locking prop nut for safety. Perfect for FPV racers!
