Simple FPV Tilt Stabiliser

I have just taken receipt of a Fat Shark Attitude V2 kit from Unmannedtech. A review of the kit shall follow in a post later on, but in this I wanted to say about mounting the camera. 

Introducing the OSQ450

When I started to build my quad I really wanted to make my own frame to use. However there were two factors that stopped me being able to attain that dream:

1. Inexperience of quad design,
2. No equipment to prototype with.

The first one is quickly lessening as I use the experience of building my quad, learning what I liked about the F450 frame and where I needed it to be different to fit my needs. Having taken the skills I have developed I felt I was able to design my own machine, that leads me on to the second issue.

Battery Charging – Mains Supply with ATX PSU

Most of the LiPo chargers available seem to run from a 12V supply. This is great if you are in the field (or in a field!) and want to recharge your batteries from you car. However it isn’t so good if you are trying to charge while at home. Sure places like Hobbyking sell plug is PSUs that can run the charger, but I want to reduce my outlay somewhat and I also have a few PC ATX power supplies laying around.

-UPDATE- Link to 3D models I used.

Landing Legs

One of the issue with the F450 frame is the limited clearance under the frame. If you want to add an under-slung gimbal, or even a battery, you may need more clearance. The biggest issue adding your own landing gear is the lack of attachment points. I decided I wanted to add extensions to the existing landing legs mainly for cosmetic reasons, I didn’t like the idea of ‘horns’ sticking out for no reason.

Build Continuing – APM Mount, GPS, Landing Gear

As I continue to build my Quad’ I have had to solve a few issues. After reading on the ArudPilot website about the compass (and GPS) module, I needed to mount it away from sources of interference; the ESC and motors. As both can output a magnetic field it seems. Again I turned to my trusty 3D printer to produce a design I made to mount the GPS and compass module on a mast. This sits about 100mm above the top of the frame, which is about as far as I can go with the length of its cables.

Build Started – 3D Printing to the Rescue

The build has started! My parcel of parts turned up on Friday (most of them anyway, still awaiting the motors and props – more on that later). I got home all ready and excited to start my build and just as I finish making the obligatory cup of tea (I am British after all!), the power failed.
