So the Diatone GT M5 that I bought went up in flames (well ok one of the ESC’s did). I was too impatient to wait for Alex and team to send a replacement, so I bought some new ESC’s and that’s when the problems started. I’ve invested time in a fairly decent soldering iron with multiple tips, several hours worth of watching YouTube videos (I didn’t realise there was so much to soldering!) and thought I’d have a go at connecting the ESC’s to the flight controller. That’s when the problems started!
The solder on the board wouldn’t melt despite my hottest tip. The iron melted my solder quicker than you could say liquid metal, but the stuff on the board - nope! Even the de-soldering copper braiding didn’t work and just ended up going into the surface and then pulling into lots of fine copper filaments making a short circuiters dream! I even waited until the heat of the midday sun was out to give the soldering a helping hand! Nope, still no melting.
So is there some dark secret to de-soldering the solder from bought flight controllers, or do they use some dark Chinese secret for combining the solder into some super element that can never be melted, even on the surface of the sun?
I now have a baked F3S flight controller which seems to be totally overcooked. I’m hoping that the replacement doesn’t have pre-soldered holes and that I can use my own solder on it!
So hints and tips gratefully received
