secret2475 @MarceloGomes V761 protocol should work fine. It does on my Jumper T8SGv2 . Channel 5 works to mix a switch to select the 3 flight modes of beginner, intermediate and expert. I'm not sure yet which channel works for the 'stunt' mode select, but I kind of don't care, which is why I haven't put in any effort to find out.

secret2475 I also want to know if you ever solved it. I've been trying to bind with my T8SGv2 also without success. Fairly frustrating as the protocol is supposed to be GD00X GD_V2 as far as I can tell, but I don't see a way to set that sub version in the Jumper.

secret2475 What color are the lights? Do they toggle on/off from the transmitter?

secret2475 The power connector is actually a Molex Picoblade 51047 series 1.25mm pitch, not a JST.
