A regular at the field has an Avistar with a 4-stroke in the nose. He had to cut a hatch and mount his battery as far back in the fuse. as the wires would allow. My battery pack is square, I guess I could spring the cash and buy a flat one. Would slide under pushrods a lot easier. I'm going to build a test stand next week and borrow an electric starter, will get that S-T to run or else!
