SPEED-PLUS motors, LEHNER brushless motor<br />
SPEED PLUS motors<br />
with integral speed controller, combining<br />
reliable operation with maximum possible<br />
operating convenience.<br />
● LiPo-compatible: two to three LiPo<br />
cells<br />
● High-performance BEC receiver<br />
power supply<br />
● Strain relief on connecting leads<br />
● No cables between speed controller<br />
and motor: increased efficiency,<br />
saves space and weight<br />
● EMF brake as standard, for use with<br />
folding propellers in powered gliders<br />
● RC system is switched on by<br />
connecting the flight battery<br />
