FEATURES:

The KIRA FAI motors are brushless in-running motors which are perfectly adapted on sailplanes, RC cars and speed boat drives. 
High motor RPMs together with the internal fan keep the KIRA motor cool and the gear box brings high torque in comparison to low weight. 
The slim size fits in nearly all fuselages and the over-all effeciency due to bigger propellers allows incredible flight performance.
KIRA FAI motors are adapted for competition demands. They satisfy the highest performance standards at the well-known reliability of KONTRONIK Drives products.
