Gear-boxes for below 1W propeller motors

A complete family of gear-boxes for 5-30
grams slow flyers
With its M0.3 gear family, DIDEL has defined a complete
and coherent set of one and two-stage gear-boxes, that will match any
need in the slow flyers community: small and large motors, small ratios
for small propellers, high ratios for large efficient propellers. A progression
of 25 to 33% exists between two consecutive ratios. This means that any
propeller can be matched with a gearbox to be very close from the maximum
of efficiency.
Three possibilities exist for connecting your propellers:
1mm axis, 2mm axis with a supplied adapter to be glued on the 1mm axis,
and of-course the DIDEL propeller connectors PC1 (1mm blade rod) and PC2
(1.4mm blade rod).
Gearbox and motor assembly can be conveniently fixed to the plane structure
by two 1.4mm carbon fiber, without any glue.
Gearbox weight is between 0.5 and 0.75 grams, depending
on the diameter and gears.
Gearboxes are delivered as easy to assemble kits. See
documentation for 1 stage, 2
stages small motors, 2 stages 10 mm motors.
Several of these boxes are available now from our distributors.

Propeller connectors
The "connectors" proposed by Didel press-fit
directly on the last gear. Thusts of more than 20g are easily absorbed
if there are no vibrations. Home-made balsa propellers are easy to
do (see www.didel.com/slow/propellers/BalsaProp.doc)
and several people have made compatible carbon foil props. |
