Pocket drone dreams


Don't be surprised if the camera stays earth bound until the sonar obsession wears off. We're going to use DT700's, 30A ESC's & large corotating props for the camera. To make the Chinese shipping economical, this has to be combined with the orders for ghetto rotor & pocket drone. Maybe we'll just move to China & be done with the hassle.

Have a budget for an extremely small servo or biometal actuator for yaw. Looks like the micro RC parts & bio materials R becoming more common & cheaper. Bio metal would drastically cut the weight of the yaw control. Most of the cost is patent royalties.

No-one has ever documented a coil servo in motion. From the low resolution pictures, they appear to have a permanent magnet outside the coil & a permanent magnet on the armature. When the coil is off, the outside magnet pulls the armature. When the coil is on, the coil pulls the armature away from the outside magnet. The armature has a source of friction to stabilize it.

We'll probably end up with a DIY linear motor. Oh & 1 other thing. If U think the pocket UAV hasn't already been done, think again. The inventor of the Picco Z already made one. It's a fully autonomous, gyro stabilized Picco Z being sold to European governments to fight the red menace. The red menace across the pond, that is.
