Contemplated gearboxes combine a high numerical reduction ratio with the capability of transmitting power at a superior power to weight ratio using a compound star planetary gearbox configuration (110) that is radially expanded using hollow driveshafts (140) to link the planet gears. In most preferred compound planetary gear arrangements, planets of different diameter are torsionally connected to each other, or mesh with each other. Input and output gears counter rotate while the planets rotate in bearings (149) anchored to a static casing (115).
