Plettenberg
has expanded the HP370 series to this huge /50 size motor, particularly
suited to power large airplanes with tremendous power. It will easily
power over 20lbs airplanes and swing props up to and over 20". It can
be powered by 30-36 cells or even more voltage when using Li batteries.
Recommended esc is only Schulze high voltage fut 40-70. Compared
to some other combination to achieve this amount of power, this motor is outstanding,
no gearbox, nor the need to combine two motor (and two esc), light,
simple, powerful, efficient and reliable.
