The Moth was great but I flew both it and this Boeing F4B-2 that is a 68 incher designed by John Tanzer, it's a very easy plans build but it had a mistake in the CG area. It came out at 12 pounds but required everything in it to be moved behind the fire wall then three pounds of lead in the cowl. It flew OK for a heavy slug and I still have it. Pain in the butt to haul though. If kept in the 12 pound range it's a great flying machine with a lot of history. If I wasn't out of my Bipe stage I would have built another one. Very easy to fly and land but I still give the Moth the number one for relaxed flying.
