When I started flying RC only a very few people hooked up there battery directly to the bottom of the starter, the power panel ruled the flight line. It still does for the most part but as soon as people start using bigger engines they notice there starters don't have the zing needed to spin over there bigger engines and start looking around at what other people are using. My flight box is still set up with a panel and I use an electric fuel pump. My battery went dead so I just left it hooked up and clip on two leads from my jump starter to the panel. Most the time I use something like a hot shot for my glow driver but this time of year I use the driver from my panel, I can get more heat out of it and my engines start easier. If I had the money to be changing over there are some very good starters with some outstanding battery packs these days. Until I hit it big I will be living in the stone age though and just keep doing what it takes to stay in the air. That big drill my buddy is using looks like a pretty good idea to me, it even comes with all the stuff needed to be used as a drill and it has a charger in the box. Even comes up on sale!!!
