The canopy protects the precious electronics. It makes the aircraft more aerodynamic. Lastly it makes it look cool. It was designed for easy assembly. Includes holes for camera, antennas, USB port, and easy screwing.
The frame is the most important part. It needs to be robust but still light. It was originally designed by Bludz FPV. I remixed his design making motor assembly holes easier to use and not blocking motor rotation.
Battery & Landing Gear
For easy liftoff and land I made those landing gears. They also hold a battery. Use velcro strap to keep cables away from propellers.
Assembly is very easy. All you need is four M2.5mm screws. Three short for battery holder and rear canopy attachment. One longer for front that also blocks camera for falling inside.
