Evening folks... I been going thru my old junk boxes... And using just old spare fcs and escs and just whatever I have, to put together some beater quads. Partly to work on my tech side skills on the guilds an partly so il l have some extra birds laying around in case a friend shows interest con fpv or I meet someone while Im out flying that is interested but intimadated by the cost of entry in to our little world.. Bam!!! I got an old quad I can throw their way. I've been blessed in this hobby so I'm paying it forward a little maybe. So reason for my post.. I found a hobbywing x rotor convertible f7 fc... Mine is the dji ready fc with the plug in for your Vista. Well I have a couoke of lifted pads so I'm really slim on uarts. I found a tx5 pad but for the life of me cannot not find rx5.. Anywhere. And in betaflight ports tab I have a uart 2 but I'll be damned if I can physically fidn one on the fc. Can't find these two anywhere in any documentation on the net. There are four pads directly behind the boot button unmarked.. Maybe there idk.. Help.
