My 3D printed racing drone is done. More or less. I was able to finish it a few weeks ago and even perform a maiden flight. It survived the experience, but I also discovered few problems I will have to solve before officially calling this project a success.
First of all, the decision about hard mounting a flight controller and not installing a capacitor on mains was a bad one. Not only motors are “twitching” from time to time, a video is very noisy. I hope big low ESR capacitor will solve that, since there is no way for soft mounting for this frame.
Besides that, it worked just fine. I will try to prepare a video from the maiden flight in a few day, for now only a few pictures and final specification:
- Frame: PLA 3D Printed, 220mm motor-to-motor diagonal
- Motors: EMAX RS2205S 2300KV
- ESC: Racestar RS30A BLHeli_S
- Flight controller: FrSky XSRF3O running Betaflight 3.2
- VTX: TS5823 200mW
- Camera: RunCam Swift
- Total weight, no battery: 380g
Total build is, of course, heavy, but not that heavy as I feared. I was expecting something way above 400g. The frame is also quite stiff. I wonder how much beating it will be able to take….
