Cube orange with walksnail

Hello, I have a bit of a problem with cube and walksnail

Situation is following: Cube orange on mini carrier board on wing, plus walksnail avatar pro vtx.
Walksnail power input is specified 6-22V

  • I can power it directly from telem port, works like charm video plus OSD, but it will burn down telem port - not enough power
  • I can get power from battery and only GND+TX+RX from telem port - technically should work but actually no telemetry thus no OSD
  • I can power it from telem port and servo rail simultaneously because servo rail has extra power from 5V BEC - it somewhat works but OSD characters flicker randomly, altho OSD data is correct

Whats the fourth option to get this combo correctly working?
