RE: Capability of DYNATRON starters?
We use the Dynatron with two 12 volt lawn mower batteries hook in series and it will zing A G-45 with ease. It does tend to get hot if your engine doesn't fire up after a couple of tries though. Due to the weight of the two batteries we installed them in the bottom part of a plastic rolling tool box. I use one of these boxes for my flight box set up for glow planes. The easy answer would be to buy a starter with the gear system or make a starter yourself. I used one made from a Toyota Truck starter with a small 12 volt battery for starting my G-62s all the way up to a Fox 100 twin. It was cheap to make but heavy. There are several ways to start the bigger engines, I went back to the spring starter on the G-62 I have now, with only one big engine I can't see myself spending the money or hauling a heavy starter around.
