Rob's Hangar

Maiden flight of my PicooZ (PicoZ, Pico-Z, Havoc) with 2.4 Ghz Walkera RX2406. only 2 Channels Used. Super smooth flying, no cyclics, foward speed is only controlled by center of gravity. AUW 12.4 g. held together only by clear tape.
thanks to EQMOD on RCGroups who did this mod first.

for the cyclics, im planning to use the actuator / servo board mod, here is my test-bed video:

Some outdoor flying with the walkera 4#3B sub-micro rc heli, rewound C05 main / flea, HP03T tail / flea, RX2406.

amazing 7g micro helicopter

also great, MFujinawa’s Rotor head design with actuator.
see the thread on RC Groups 6.25g Micro Helicopter

The Norwegian company Prox Dynamics just released videos of their PD-100 Black Hornet, a 15 gramm fixed-pitch helicopter with a direct drive brushless main motor. According to Prox Dynamics, the PD-100 is the first Unmaned Aircraft System (UAS) to be developed.

The copter comes in a box of three (always better to have more than one heli!).

Just too bad that this machine will probably never be available for the regular guy.

RTF box - millitary style.

The box.

The PD-100 has a rotorspan of 100mm. With a weight of 15g it is about as lightweight as a PicooZ.

• Rotor Span 100 mm, Mass 15 gr including Payload
• Maximum Speed 10 m/s, Endurance up to 30 minutes
• Digital Data Link, Range 1000 m Line-of-Sight
• GPS Navigation or Visual Navigation through Video
• Autopilot with Autonomous and Directed Modes
• Hover & Stare, Automatic Search Patterns, Preplanned Route

Interestingly the PD-100 tailrotor looks very similar to the PicooZ tailrotor.

Direct drive brushless mainmotor - and a tail rotor that looks very much like the PicooZ's?

The PD-100 has a direct-drive brushless main motor which can be seen in the picture above.  Eliminating the gear/pinion components from the design makes it very low in noise i suppose. Also the weight of the BL main motor is placed directly in the desired center of gravity.

Really a palm-size design. The rotor looks flybar-less. Do I see a PicooZ tail?

Looking at the picture above there seems to be no mechanical stabilizing mechanism like a flybar in the main rotor design. So this flybar-less setups seems to be stabilized by electronics. Also in the picture the swashplate can be seen – it has relatively large diameter: This makes controll inputs extremly precise (high resolution) – just what is needed for a flybar-less design at this scale.

One of the servos can be seen in the back of the heli, near the tailboom – looking like linear servos used on the Spektrum AR6400 or the 5-1 board of Walkera 4#3Q and Lama2.

Also interesting are the other, earlier designs of Prox Dynamics’ Peter Murren which can be seen on his website http://www.proxflyer.com/.
