MDF Multi-Copters for All!!!

After much testing it turns out that long arms and 9" props in a Y4 configuration has almost no yaw authority at all!!

It made the copter practically useless for AP as you couldn't keep it straight let alone pan a shot.

So I decided to go with a standard tricopter and got myself one of these:

It's a ToughTilt mechanism from flitetest.com and it's rock solid. It has an almost hydraulic feel to the movement.

After a test with the 9" props it was obvious I needed something bigger.

So I went with 850kv motors and 11x5" props. This gives me a nice 50% hover:

The basic method I used was to cut the parts on my Shapoko CNC mill, although a steady hand and a jigsaw/drill can yield that same results, the sand them down to clean up the edges and ensure the holes were all clear.

Next I needed to paint them. The reason for this is a little know secret... once you spray paint any material black, it magically takes on all the properties of Carbon Fibre!! thats science kid!! :)

I use simple spraypaint and clear laquer, about 2 coats of each.

The rest is history but here are some build pics:

And Version 2:
