Delfly
Clone now includes radio
This
is a unique, one-of-a-kind prototype, based on the Delfly
RC ornithopter, developed at TU Delft, Netherlands. This model
was not produced at TU Delft and it differs from the actual
Delfly in some features. As a unique prototype, this model
does not come with instructions, and it is intended only for
the experienced hobbyist or professional user.
The
ornithopter has a 16 inch wingspan and weighs approximately
15 grams (1/2 ounce). It is a four-winged design with Chronister
scissor mechanism. The wings clap together twice in each cycle
for greater efficiency. The upper wings clap against the lower
wings, and the upper wings clap against each other at the
top of their upstroke.
The
model includes a Park Zone 3-channel RC system. The receiver/servo
unit is already installed. The transmitter/charger and flight
battery are included as well. The model now has conventional
rudder, elevator, and throttle controls - not the V-tail pictured.
At
the heart of this model is a special ABS gearbox made using
fused deposition technology at Rochester Institute of Technology.
The gear ratio is 106:1. Large, slow-flapping wings for efficient
low-speed flight. A square hollow carbon fuselage mates with
a square hole on the gearbox to prevent rotation. Special
clips are provided for mounting the battery onto the frame.
