it's cool, I do SMT soldering all the time. I'll look into the FET mod. I've also been looking into maybe doing an SCR mod. The idea I have would probably be best left to a cheap-ass bit clone, as it would make it forward only, and it would dump a ton of current to the motor, for drag only, I suppose. I've already learned that you don't use an SE for speed. You can, but it's cheaper and easier to get speed from other things. The ZZ and SE's are just for looks, as the scale is better and more realistic.
