QuadX

This is a straightforward acrobatic quadcopter frame for LOS flying. It's a sturdy design if you use 10mm carbon square tubes, which cost around $2 per meter from hobbyking. The print and assembly process are extremely easy. You can use CA glue, screws or both to attach arms to the frame. Cut the carbon tubes (arms) to equal lengths that allow blades to clear the central frame. Suitable for: 2204 motors with 16x19 spacing Print Settings: Printer: CTC Rafts: Not necessary Supports: Not required Resolution: 0.3 mm Infill: 100% for motor mounts, and 60-70% for the central frame is sufficient. Best results are achieved when printed with ABS, but PLA also works well. http://www.thingiverse.com/thing:941246 I used this design to protect my Naze32.
