Thanke Plane Jim. I fly at a dry lake so dead engines present no problem (:-). I have however been looking at the glow power for four strokes as any true addict would. The $70.00 looks a little steep though. Perhaps I'll build my own.

Waaay back in the mid 80s we added a battery to our slow flyers so we could throttle way back. I just need to dig out the method from my rusty memory banks.
