I've got a gel-cel motorcycle battery in my field box that powers my starter and glow-driver. When I get home I plug it into a powerstrip on a timer that charges it for 1 hour every day (along with the receivers & transmitters and their various chargers) so I'm always ready to go. I finger flipped my free-flight and control-line of bygone days but I am a fan of electric starters now, I'm afraid. Never did get one of the Ni-Cad wireless glow-drivers. I may be in a big minority with that.

I hand flip the gas engines, but they have big 'ol 16" or 18" props and I wear a double padded glove. Whole different animal.

My fuel pumps are manual Dave Brown six-shooters of various tubing for glow or gas. Manual in & out. Takes a little longer, but so far they're foolproof.
