Last week I’ve been finally able to put my new mini quad into the air. It’s based on Reptile XR4 220 frame. Looks like I’ve succeeded with my build this time, since there were no major problems. Few minor, yes, but no major.
My Reptile X4R 220 mini quad has following specification:
- Motors: EMAX RS2205 2300KV
- ESC: FVT LettleBee 20A
- Propellers: DAL 5040
- Flight controller: SPRacingF3 clone running INAV with asynchronous gyroscope and accelerometer. I’ve already written few words about async gyro updates here
- Radio RC link: ***FrSky X4R-SB***
- Camera: Runcam Swift
- VTX: TS5823S 200mW
- Matek PDB-XT60
- Micro MinimOSD with MW-OSD 1.5
Here is short, uncut, video from maiden flight:
The only problem I’ve encountered, was with OSD. It stops overlaying data on aggressive maneuvers for a second and then OSD comes back again. Probably it’s because of voltage drop/noise. MAX7456 is extremely voltage quality sensitive. I will try to fix that with additional capacitor on 5V line this weekend.
