Printed Tricopter

thingiverse

The current design of my printed Tricopter is being scrutinized for improvements, possibly due to my piloting skills. The center plate tends to break easily, while the Quadrocopter design (http://www.thingiverse.com/thing:4812) appears sturdier. Despite its foldable feature, the Tricopter has a larger diameter and weight than the Quadro, which could contribute to rough landings. The motor plates are designed for 2213N 800Kv Brushless motors (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8622), but other motors may work too. Use 10x10mm aluminum or wood profiles for the arms, with 40cm long arms and 10" props. Initially, KKMulticopter controller electronics were used, but now a MultiWii controller is preferred due to its additional features like auto leveling, barometer, and magnetometer. See the photo gallery (https://picasaweb.google.com/ZaggoPS/Tricopter?feat=directlink) for assembly details. For the servo assembly, you'll need a 624 ball bearing, M4 x 20 mm bolt, washers, and a nut; also, two M3 bolts, washers, and nylock nuts. The snap-in hinge information can be found in the "Two Tricks" blog post (http://pleasantsoftware.com/developer/3d/2011/04/07/two-tricks/).
