The HP 300 series is an addition to our program of geared motors. The motors have 8 poles and are brushless.
Due to the integrated gearbox it became possible to adapt the enormous power of the HP 300 to large model gliders needing higher voltages of over 20 Ni cells.
The gearbox with needle bearings is well constructed and proven from our own in house production. The power-to-weight ratio is exceptional.
Special features include a hardened 6mm shaft, 4 ball bearings and neodym magnets.
