Reptile X4R 220 – maiden flight

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.

  1. Good post. Which GPS/magnetometer/barometer are you running here? How far are they from the FC and ESC’s?

    I have been having a similar problem with my micro MinimOSD. With the motor spinning, I see lower voltage readings on- screen, then what I measure with the voltmeter. I am going to add a 1000uf cap to the battery and see if that helps.
