I have bought a sensor v3,new from my local hooby shop jonathan in italy.
I use two lipo 2S directly connected to sensor v3 fully charged to 8,4V: BATT 1 led (sometimes BATT 2 too) lights up blue but randomly become violet (or white/red?) too fast to identify the correct color. Why? It is defective or it's normal? there is no power supply interruption to receiver with only BATT1 connected.
BATT1 and BATT 2 programmed as Lipo, with HV output.
