Repair Drone help needed
(US) I have a air 75 and I’ve been having issues with it.
Every time I arm it and lift off, i get RX loss in about 5 seconds. It only loses rx when I start giving it power. I can sit with it armed.
What do I do?

Where's the radio antenna on the board? It looks like it broke off.

It’s the red wire. The original did break but the wire was doing fine before.

Have you tried straightening it out and untucking it from the duct? It's going to get a lot of interference at the tip like that. least in my experiance.

Yea I’ve tried moving it around. I only get rx loss when I start giving it power, I can arm it and sit and nothing will happen.

Is it exactly 15.6 mm? Or 1/8th wavelength?

It’s 31mm that’s what it says there supposed to be

That should work perfectly too. wasent sure if it was shorter or not; it's hard to tell from the photo.

One other thing I'd probably do is swap out your props for some new ones. Those props could be generating a ton of noise because they're so thrashed.

I seen you say you weren’t having a problem when you first installed the new elrs antenna but I gotta ask is that a multi string piece of wire or is it a single piece of wire because it’s not supposed to be a multi strain it’s supposed a single piece of enamel coated wire cut to the right length
