Whatever props you end up using just do a short run, check temps often. I've run the AQ 1800kv motors pretty hard and they are tough. I try to keep my temps below 120F.

Well just ran again 5 min 4s m445 temps 130 motor and 118 esc then got another desolder

With temps like those, most likely your problem is cold solder joints which are not strong enough to handle a little heat. What solder are you using, and what wattage iron? What tip on the iron?

I am not going to lie I suck at soldering It's just a 40w. 120v with a square tip but I need to get a point
