Co-axial RC helicopter, eSky's  'Lama V4'

You can see the servo, motor, flying adjustments and wiring.

 Probe idea from Predator UAVs - install a camera on a RC aerial vehicle.

If not able to install a live feed camera, I thought I could attach something like a phone with a video recorder. 

Researched and found many people were already doing that, and selling set-ups online.

For example:http://www.youtube.com/watch?v=xebWJ84JC84

Video camera transmitting was too expensive ($200+ for the transmitter alone) and may be too heavy.

 I wanted to make the set-up myself.

The mobile phone weighs approximately 110g, the helicopter 200-250g. With the phone, it couldn't lift off, although hovered on the ground. Also, it seems that this small helicopter is only good for indoors as strong winds would blow the helicopter in a particular direction even if the helicopter is strafing/moving against it.

Also, hit a tree and after a few more times of flying, the helicopter could only turn it's bottom rotor blades and not the top ones. Will have to work out why and fix it.

In the future: build a more powerful helicopter suited for outdoors. I wonder if I could just replace the motors and rotor blades and add an extra battery ...

More photos/videos to come.
