I know what you mean, I was mighty tempted.
Speaking of those starters, I have a Hobbico 180 with a Miller 3.5 to 1 reduction, it came with 4.0 to 1 reduction but was so slow that the Maloney mags would not spark. I don't have any more big gas engines. The 180 would not turn my High Compression 150 even with a 300 amp garden tractor battery.
I got a message back from Becky at Sig saying my pictures were passed on to a "tech", no word from him yet. The plane I was all excited about is in limbo.
