Pentacopter

Building currently - check back soon for images and firmware download. You might want to use a mixture of acetone and paste to connect the pieces and smooth the transitions smoothly. You'll need support enabled for all parts involved. I'm using two 1 1/2" diameter motors on each side, and three 1" diameter motors for the rest; they're all bi-directional with three prongs each. Recommended propeller size is a 5" radius. This design is rather large, with a wingspan of over 1 1/2' without propellers; ~2 1/2' with propellers attached. The battery pack measures 4 1/2" x 5 1/2" x 1 3/4". It's designed to house (7) AP13G3N batteries, totaling 4.6 Ah. The BMS, sensors, and IC fit under its body; you have 2 1/2" of room on the y-axis if you fill the battery pack, or 4" if you choose to use your own. Design and print a cap to fit your specific needs. This copter is designed to handle up to two motors failing without crashing; giving time for the firmware to reverse the propeller and unjam it (hopefully). It also can just use the triangular pattern of the three motors if the batteries are running low, or you don't need the speed boost from the larger side motors. The improved grip on the bottom should help with landing on uneven surfaces. The "wings" are designed to be aerodynamic under the predicted forward flight angle.
