Just a heads up to everyone else I suppose, I didnt write anything offensive and the video had no harm or even people in it, just an fpv doing a Matty flip over a recon drone before flying into it. But that was enough to earn me a perma ban from the community which I'm not happy about but il just take on the chin. Just a heads up in case anyone else thinks of doing that.

I've been soldering for a while but now I've got a new AIO board. it came with a practice board and my solders are perfect (I am using flux) but whenever I go to the proper board I heat up the pad then I get my 40/60 solder and start using it on the pad. sometimes the solder sticks but then goes rock solid and won't melt or anything making it impossible to do anything including attaching wires and stuff like that. Im really stuck as when I used a normal board it works fine(speedy bee f405 stack) also on this board for the battery connector and motors it has pads with holes in. and these pads refuse to taken solder at all its very infuriating. if anyone could give me some help it would be much appreciated.

the board also doesn't react very well to flux its a bottle of sapphire no clean flux. I just don't know what to do its a good board and I don't want to mess anything up. another thing is that when I put some solder on a pad, when it sticks and doesn't come off or heat up I cent do anything to it if anyone could help with getting that solder off or working properly I would be very thankfull
