Maybe if you are winding a 540 armature, but there is no way you are getting that much wire on a 130 armature. I doubt you could even fit 60 turns of 28 ga, though I could be wrong.

I noticed when looking online for magnet wire just how much difference the guage makes in terms of the length and thickness of the wire. They generally sell magnet wire by the lb, and not by length. For example, a pound of 28ga gives you 1989 feet, while 30ga gives you over 3000 feet, and 32ga gives almost 5000 feet!

I've got two spools of wire coming (28ga and 30ga) so I'll be doing plenty of experimenting in the coming weeks.

As for what is safe on the FETs, the only way to get an idea is to measure the current draw of the motor. Remember that we still don't know the specs on the stock FETs. When I get a chance, I will connect up various motors directly to a set of batteries and start measuring current draw. That'll give us an idea of where the stock motors fall, and what will be OK for the FETs. I could probably even include NML's Stage 10 motor in the chart, as one of my friends has one.
