Micro (13.5mm motor span) Quad Frame

thingiverse

As I had a few MultiStar 1704 motors sitting around idle, I designed a compact frame to utilize them effectively. The motor spacing on this frame is 13.5 mm, which allows for the use of 5-inch props as the maximum size. The main plate, printed with 50% infill and a 2mm shell thickness, weighs 33 grams and appears rigid enough. I designed the mounting holes for MultiStar 1704 motors to be 14 mm apart. Future versions will accommodate other motors as well. If desired, mount your flight controller on an anti-vibration plate using rubber mounts (e.g., http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=37447&aff=1479188) to help counteract the imbalance caused by cheap props. For enhanced anti-vibration performance, I've created alternative designs ("_alt" in file names), which relocate the battery plate through holes in the main frame to the flight controller plate mounted with rubber mounts. The added weight of the battery results in improved dump performance. To further enhance stability, consider incorporating a mini PDB (http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=56831&aff=1479188) into your design, as it fits seamlessly within the frame. Additional components include top and bottom plates: a top cover for the flight controller, specifically designed with Naze32 in mind, and a bottom plate that serves as a landing skid, battery holder, and protective cover.
