iced,
in one of your post you mentioned you would be able to compensate by using a lower throttle. not always, if you bump in to something or the ground the flight controller will see this as an un commanded movement/input will try, very quickly, to correct it. it will happen in milli seconds, can and will spin the motors to full rpm trying to correct the situation.
when this happens, most likely you will loose orientation, the only thing you can do in this event is disarm quickly.
i've only had this happen when i have airmode turned on, i have airmode on a switch, by default in betaflight airmode is set to always on.
none of that probably means much now, make a mental note of it for the future.
something i didn't see mentioned is s solder and soldering station, something like
this at amazon and some solder of course.
i forget where i found the soldering station i have but it was like 30$ and has suited my needs.
and yes you want something you can control the temperature of.
