Scott, Keith, Dave, Mike, Ronnie, Paul, et al,

How could that many smart pilots be dumb....I'm doin' nothing...except test
it!  By the way, how does the Velo fly in ice?

I think trying it out with 14 volts is a good idea.  Its just a resistive
heater. 

Be careful when you test it, those things get really hot when there's no air
blowing over them.

I know of a few products that you can pull 24 volts from two 12 volt
batteries but they are not flight hardware, I wouldn't even consider using
them and risk an electrical fire.
