Rev One Quadcopter

thingiverse

Update: This "Revision One Quadcopter" design was created in Tinkercad back in early 2012 and has now been released for public use. The builder claims it is easy to assemble. However, support for this quadcopter has been discontinued as the creator has learned new tricks and plans to release better models soon. To build the frame, you'll need essential hardware including 24x35mm M4 socket-cap screws, 16x25mm M4 socket-cap screws, 16x14mm M3 socket-cap screws, 4x6mm M3 socket-cap screws, 4x20mm M3 nylon standoffs, M3 and M4 nylock nuts, and at least 1m of 19mm/1.5mm square aluminum tubing. The motor mounts are designed to carry 28xx series cross plates of your motors. When printing, print the motor mounts and landing gear at 100% or so, while top and bottom center hubs should be printed with at least four shells and no less than 18% infill. Cut four 235mm long pieces of aluminum tubing and clean/file the edges. Use "tool-miter_box_90.stl" for perfectly perpendicular cuts if needed. Slide "tool-hole_drill_template.stl" on the end of each bar, mark holes, and drill using a 5/32 inch bit. Test the fit of bars in hubs and refine as necessary. Assemble the quadcopter by inserting motor mounts into one end of each bar, securing with 25mm M4 socket-cap screws and nylock nuts. Insert 35mm M4 socket-cap screws into bottom hub holes, align with bars, and attach top hub with add-on shelves in triangular cut outs. Secure the top hub from underside using four 6mm M3 socket-cap screws, 20mm M3 nylon standoffs, and nylock nuts. Assemble landing gear with aluminum arms and ESCs, keeping them loose to adjust for wire slack. For a detailed guide with images, visit http://goo.gl/gGZf7.
