Tricopter
From CGW Wiki
This build was based based heavily off of rcexplorer's Tricopter V2.5 with only a few modifications as a result of changed parts.

The Build
Frame
- Print out RCexplorer's frame template, which can be found Here.
- I decided to go with the coffin design, as he calls it, and just cut from each corner to the next. This allowed more mounting area and took less time to cut out on the band saw. Again, for lack of materials and money I went with a peice of 1/8 in ply wood for the frame. This not only saved time but also contributed to a lighter tricopter in the end.
- Next I cut out the arms. I decided to use some bamboo flooring I had around. This was just another factor of trying to build it really cheap. The Bamboo flooring was 1.5 cm thick so I just left the thickness and cut the other dimension to 10mm. The arms were cut to 48cm long.
- I also used longer 10-24 screws because the 3mm screws I bought from Hobby King were not long enough with the thicker wood plates and arms.
- Then I just put all the screws through one plate, added the arms and filler piece in and sandwiched it in. Although I would use locking nuts, I didn't; however, lock tight is required regardless.
ESC's
(Electronic Speed Controller's)
If you like soldering, as I do, this is the fun part.
- The wires that come with the ESC's are not long enough for our 48cm arms, and the dont come with bullet connectors. I simply added extra wire on to the end of the existing wires. If you'd like to make them look nice you can cut the ESC's open and solder them directly to the board after removing the old wires.
- Next we need to solder on the bullet connectors. Simply push the wire into the end of a female 3.5mm bullet connector and solder it in. You can heat the out side of the bullet connector and push solder in through the braided wire.
More coming soon...
