Actro motors combine the most modern drive technology and best robustness properties. This combination makes actro motors ideal. The following properties characterize actro motors:

+ brushless, sensorless commutated synchron motor
+ outside rotation motor for high torque
+ nearly wearless, because free of mechanical collector and gear boxes
+ high efficiency and polished construction lead to best thermal and
mechanical robustness

Like actro motors, actronic controllers are developed for rough everyday application. Numerous safety features like
+ temperature supervision (not 70-32 heli),
+ undervoltage supervision
+ current limitation,
+ protectiuon for motor start by mistake,
+ fail-safe-function for PPM-receiver,
+ Optokoppler for reduction of disturbances
