The key to soldering your main power wires to the board is:
-a higher wattage soldering iron, or cranking the heat up all the way
-a larger tip (or laying your tip on its side so more of it is in contact with the copper pads)
-lots and lots of flux paste or liquid flux

Especially for the negative battery pad. It’s connected to the ground plane in the esc or aio, and it sinks a lot of heat.

If you ever need to remove the conformal coating, 99% isopropyl alcohol works well (91% works also). If you ever have a warranty issue, don’t mention the conformal coating, and scrub the board down with a toothbrush and iso alcohol if they want you to send it in. If they know you’ve applied conformal coating, they’ll void your warranty. But, your warranty will also be void if you crash into water, and if I recall correctly, you fly in a potentially wet environment- so the protection from conformal coating sounds like it’s worth it.

Regarding your question about capacitor placement, here’s a short video:

I have reviewed many videos on how to properly solder wires in a drone). And did everything as you described. But the lack of experience and fear of burning the board still played a role). 

I already had to deal with the removal of conformal coating when the wire soldered off after first crash)
