Tricopter build: Yaw mount
The method I'm going to try for the yaw mount is to drill as far into the main arm as my drill bit will go and insert a 5mm carbon rod. Then drill through the remaining block, about 1.5" long which will be able to pivot on the carbon rod. The fit on the rod is snug but not too tight. The hardest part was drilling a vertical hole in the centre of the 12mm x 12mm Tas Oak arm without going crooked and drilling out the side.
Tricoper build: The frame
The frame is cut from 1/4" ply and the arms from 12mm x 12mm Tas Oak. I've used 1/4" metal bolts for now but they'll probably be swapped for nylon down the track. The hardest part was using the jigsaw to cut the base frame around the smaller curves near the arms.
Tricopter build: Parts List
The tricopter bug has bitten and I've ordered the parts to build one. Technically it's a present from Santa so I might have to wait until after Christmas to put it together.
I'm taking direction form two main sources;
- http://www.rcexplorer.se/projects/tricopter/tricopter.html
- http://www.rcgroups.com/forums/showthread.php?t=1142429
Trying to order the exact same parts from either build is tough as a lot of the parts are on backorder at hobbyking () so I'm hoping what I have ordered is suitable.
For those not familiar with Tricopters, here's a video of one someone else has built and successfully flown.
