Truglodite, the motor number itself is cn12-rxc, as you said. The "H" comes in when you give the number for the ducted fan unit.

I've also noticed when I ordered from Tower that they have TWO numbers! They can't seem to be consistent!

You will also see different voltages listed depending upon the application. I don't think they are always indicative of how much voltage they will handle (Notice I said " not always" ), I think sometimes they are indicating, for example, you will get this many rps @ this voltage.

Trug, thank you for the info on the charger and the voltages. I'm looking at the Cellpro, unless I find another one I prefer under $100.

I'll add this note, I did do a dry burn in for about an hour with the last motor, and it has lasted longer than the others, I'm sure.
