Reply to "Legacy F3 Intermittent response to Aux1 smoke commands"

I've seen a couple of meltdowns in person, and repaired a few more. It is spectacular smoke for about 20-30 seconds before the smoke unit resistor and PCB burn up. The stink of burned PCB lasts for years! Both of my in person experiences were with diecast steam, so no shell melting. In a diesel if that happens it will melt the shell if you're not quick on the power switch. In command mode the normal 6-7 watts in the smoke unit ends up being 45-50 watts when the regulator shorts, that gets pretty exciting!
