is there a ground to be concerned about, or can I just solder back on the connector?

A 2.4 GHz antenna is only about 1.25" long. If the wire that came off is short then there's no ground. If the wire is longer, say 6", then there is coaxial cable before the antenna at the tip and you need to solder the cable core and ground shield.

uhhhh pretty sure antennas are 2 wires, positive and negative. but im no expert. If it has 2 antennas i have flown with one just fine before, having ripped one off myself. Do a range test (range test mode on the tx)

I think this is a 2200mah nimh pack, 4x AA batteries basically.

oh yeah and on those non pcb antennas, just the floppy cable, the only actual transmitter part is the unprotected end of the cable and that unprotected sections length is very specific and should be kept' straight if you can.

That's the antenna part I'm trying to describe. Only the tip is the antenna. The wire section that leads up to the bare antenna tip is shielded coaxial. The shield has to be be soldered to Rx ground. Two connections at the Rx board; antenna and shield.

Some receivers have two antenna. Probably most newer receivers but it isn't the rule.

Many small micro receivers have only the short antenna tip soldered to the Rx board and no extended coax before it therefore no shield to solder.

Latched, ready for maiden

@TooJung2Die - I was afraid of that - will see if it is possible to resolder the antenna clip to the board which will have signal and ground to orient - might need a magnifying glass? 😀

@thenated0g - good luck, looking forward to the video! 😀

I need magnifiers. I have two strengths of reading glasses for my work bench and head strap magnifiers for real small work like soldering to Rx boards. You said the whole antenna connector came off the board. If you can't get the connector soldered back on you might be able to solder the cable directly to the board and eliminate the connector. It'll save the Rx.

Fixed a couple and yes you need a magnifying glass . Oh and it is really fun stripping those tiny little coax wires and make sure you don't have a little straggler of a wire that grounds it out

Running out of room in the shop. Had to hang it until i get a maiden in.
