my naze32 started acting funny ( flipping and crashing mid-flight , wouldn't arm) but all the led indicator lights still worked, it still responded to my transmitter , checked all solder points everything seemed to be good. plugged my name into cleanflight the CPU load was bouncing from 400-500% just by plugging it in, i knew there was something up with the flight controller, after 3 days of assembly and reassembly i finally was frustrated enough to just order a new Naze32. waiting for arrival of my new FC i was just messing around with some things in my shop and it clicked. i remember watching this video that stingerswarm made about fixing his VTX by throwing it in the oven @ 400 degrees f. for 30 min. so i though WTH why not try it. so i removed what plastic i could from it and set my oven to 400 degrees, i let it preheat then threw it in for 30 minutes turned the oven off waited probably an hour then pulled it out. plugged it back into my computer and the CPU load was back down to 15%. you never know whats gonna work until you try it for yourself....... happy flying....happy crashing.....happy building!!!!!!
FIXED Naze32 by Putting it in the oven!

We used to temporarily fix seized hard drives by putting them in the freezer. The cold caused some metal to shrink long enough to unseize and back it up.
I'd be careful about ovens, though it can do good. For soldering joints I use hot air SMD gun, and there are soldering hotplates to pretty much do the same as the oven. Either will work to re-flow, but you have to worry about melting plastic, hotglue, and shifting things on the bottom, or them completely falling off.
Thanks for posting this, it might turn out to be a handy last ditch effort hahaha
Well a hairdryer might not be warm enough, and if it is the you will likely have the problem just solved until some heating or cooling during normal operation causes the problem to come back so re-flowing might actually be better than the oven but it is not available to many people. The freezer trick for hard dives is not going to work on most newer hard disk drives due to improved design for disk clearance , and certainly not on the newer solid state drives.I know some guys at work who swear by the freezer trick with hard drives but never an oven!
Maybe a hair-dryer would be safer as you can control the heat with your hand as you feel it?
Ya I considered the FC was garbage so I thought it wouldn't hurt to try it! I wasn't even able to remove all the plastic but I was lucky it did not melt so I got lucky! Blow dryer or heat gun might work but I wanted an even distribution of heat.my heat gun was my first thought if I hadn't seen seen the stingerswarm vid I would have done that.
Usually the plastic used has pretty high heat tolerances as it gets hot during soldering. It probably was soft, but not damaged. Also gotta make sure you don't cool it too fast, but I see nothing wrong with this trick.
If it works and is safe why not do it? If the FCB is trash what is there to loose?
