H-copter / H-quadcopter

thingiverse

Human: I built a quadcopter H-frame that measures 450 - 500mm, entirely printed in PLA. I designed it to retain the convenience of a large frame while minimizing weight and maximizing flight time, maneuverability & stability. The "snapfit" method used allows for easy addition and removal of equipment as needed. This design enables me to switch between a lightened, rugged frame and a solid stable video platform with quick removals. The quadcopter is very solid and rigid while staying extremely light, weighing 600g when built without electronics. Adding all the gear, including a 4000mah Rhino 3s battery, APM external LED unit, and GPS, only brought the total weight to 1200g. Current setup includes: 4x Keda 2217 motors with 20turn kv860 4x Emax Simon 30c ESCs APM 2.6 with GPS APM PDB APM external LED unit 3s battery alarm BoldClash fpv cam & VTX (VTX powers cam, all leads supplied) 10x45 & 11x50 props The setup flies extremely well when desired, climbs like a bullet when throttled to max, and stays solid in place when needed. My batteries are not "spring chickens," but my 2200mah 30C's last 7-8 minutes while the 4000mah 30C's manage an easy 15 minutes even with aggressive flying. Deck plates are flexible for vibe dampening and sit on rubber washers, further helping to reduce vibrations. I have seated my APM on 3m double-sided foam tape without issue. Print Settings: Printer: Colido Printrite DIY 3D printer Rafts: No Supports: No Resolution: 0.3 Infill: 0.30 Notes: Frame tubes are 15x15 square tube carbon fiber, measuring 15x15x336mm (x2), 15x15x305mm (x2). Post-Printing: I'm currently experimenting with different canopy types for aesthetics. The image shows one I'm using, but I'll add the files for a flexible curved one when I'm satisfied with its finish.
