• DXF files for CNC carbon frame

• Choose between 2S to 8S power

• Universal Battery Mount to attach any Li-Po battery

• 4" to 6" frames, in X, HX and DC style

• Over 30,000 unique combinations possible

• Aerodynamic form balancing the drone components between the frame

• Low-centre of mass for stable and efficient forward flight

• Ability to carry either FPV or GoPro mount-style cameras

• Open-source and developable

• Super-easy recharging with a standard 18650 battery charger

• Flexible component usage and electronics mounts

Update: 26/06/21Cam Mount V4 createdTo address issues with vibration and camera jello, whilst maintaining optimal camera protection, the Cam Mount V4 has been designed and added to the build. It is compatible with the 2S and 3S Li-Ion battery caddies only.

Update: 9/06/21Cam Mount V2 (for use with the undercounted Caddx VTX - as seen in the photos) was not included in the zip file. I've manually uploaded these parts!
