FPV 250 racing quadcopter – first tests

Last weekend I’ve added FPV camera and transmitter to my quadcopter. I’ve used FatShark 600TVL camera, ImmersionRC transmitter, minimosd OSD module (flashed for cc3d), FatShark power regulator and a cheap FPV camera mount I got from ebay:

The camera mount requires two servos, which can be used to provide stabilization and view “forward” even when the copter is in deep tilt. CC3D flight controller can use those two servos – see “Gimbal” tab in OpenPilot GCS (ground station).

The build itself was a huge challenge:
* the camera does not fit the mount – I needed to cut the holder and drill a hole for a signal cable.
* the camera mount is designed to point forward. I hoped to hide the camera inside the frame so it won’t get hurt during a crash, but that was not possible – I ended up mounting the camera sticking out a lot.
* there are no mounting holes or slots for transmitter or power regulator, so I tied them with cable ties. They stay in place, but are not rock solid.
* all cables are too long, but I did not have spare plugs, so I could not cut and redo them. All the cables and wires look messy

The result can be seen here:

And here is a video showing the first fligh attempts:

And a longer, uncut version showing a lot of mistakes. It’s not easy to judge altitude with such wide angle lens, so I had few close calls with a ground.
