Kontronik KIRA 500-30 6.7:1
The KIRA 500 motors are brushless internal rotors specially optimized for the needs of gliders, RC cars and racing boat drives. Thanks to an integrated fan, optimum cooling is provided at high motor speeds, while the gearbox enables high torques with low weight.
The slim design fits into almost any fuselage and the good efficiency of the entire drive including the large propeller allows amazing flight performance.
Different, finely tuned speeds are available per motor size. In addition, the KIRA 500 motors are very broadband, so that only one gear unit variant is required per motor type to cover the entire range of applications. This makes your motor selection considerably easier.
For gliders, motor models, hotliners and aerobatic models up to 750 W continuous power.
With it, gliders up to 6 kg, motor models up to 4.5 kg, hotliners up to 2.5 kg and aerobatic models up to 3 kg can be motorized well.
