| All metal planetary gearboxes for SPEED 500 & 600 | |
|
Elegant overkill! 32mm long (1-1/4" excluding shaft), 29.5mm diameter (1-3/16") outer body CNC machined from barstock, glass-filled nylon gear ring with 3 carbon-steel gears, 4mm output shaft supported by two ballbearings, mounting screws. |
Perfectly
in-line output of prop shaft and easy 2-screw mounting to front of airplane.
Use 4mm prop shaft adapters, GR605340 for regular airplane props, or
HLAN2411 for folding AeroNaut props. |

"Innerdriven" gearboxes for Jeti Phasor, SPEED 500, 600, Strontium 150’s, and ULTRA Motors |

Exactly
2:1 reduction. This has a very strong structure. We think this might
be OK for motors that put out up to 500 watts such as the large
Mega’s and Ultra’s. Jeti's Phasor Brushless motors have
a label that says clearly "for direct drive only". The
intent of this warning is to limit the Phasor motors to a maximum
of 15,000 rpm so they won't throw their magnets off.

But with a low ratio gearbox such as this, the Jeti motors can turn huge props on large, slow-moving aircraft. Short — length from front of motor to front of gearbox is only 1-1/16 inch, easy to mount on firewalls. Notice
the round flat plate in the front — use 2 or 4, 3mm screws HLH8730
for mounting. "Innerdriven"
means that motor and prop turn in same direction for maximum motor
efficiency. Prop shaft is less than 1/4 inch offset from motor’s
shaft. Double ballbearings, 5mm output shaft. About 2.5 oz.
