O.K. for whoever cares, The maiden is done. I went with the .61 fx and it did fit in the cowl. Finished and ready to fly it tipped the scales at 6.8 lbs. There was no CG in the manual so I set it a little nose heavy. Throttled up and away she went. Uneventful, it tracked straight, ended up with incredible verticle (go figure), like the roll rate on high rates but painfully slow on low rates, it will snap very fast, it lands at a comfortable pace and predictable at low speeds, meanig it drops like a rock. It will knife edge for days. Not all that impressed with this edge. It does look great in the air. The tail feathers are too small for this plane. I think they just recovered some from the .30 size plane to match this color scheme. Oh well, there it is for what its worth.
