Back on topic. No woes. The rules help the class not hinder it. Having equipment issues and refusing to use certain brands are opinions. I've had a couple of bad sensor boards in 2 brand new Balistic 25.5s. Charlie had me new boards in 3 days. The motors had consecutive serial numbers and suffered the same symptoms. Once repaired and heat cycled they run great. I have never had issues with ESCs much like Darkside. Zero dead shorts or smoke outs. By the sounds of it, there are a lot of SMT components either being floated off PCBs or burned up from overheating during installation soldering. I go through a lot of flux. I put a drop on every joint I heat up every single time I touch an iron to it. It leaves a nice finished surface too, free of burs and rough edges. I use flux even when desoldering. A good iron goes a long way too. Keep the temps up and the contact time low. The heat will be where you want it and not be using the rest of the electronics as a heat sink.
