Want to know the extremes? but don't tell Jimmy I said this
. He's got a digital weight they use for weighting in gold and jewelry and he'll weight each and every solder bit so they all have the same amount on his packs. Then with a long tweezer, he'll solder his packs together. I think he uses the brand "Kesters" for his solder and they're shiny nickel-like when it's done. Neat but waaaaaaaaaay too extreme for me. Then on his motor, he'll flatten the 12g wires and count the wires and strip the rest and solder it the same way so they're perfect each and every time. Don't even get me started on what he does to his ESC.
