Hey Shortman,
I like my SE very much, although I have made some other mods to it. The ARF version has a 5/8" .035 aluminum wing tube, so it was easy for me to move the wing forward 1.5" by building a new wing tube 1.5" ahead of the existing one. I added TWO inches to the rudder, replaced the short stubby gears with a Dubro plastic unit. The plane became more pitch stable and balanced 1" behind the high point at the spars. This was actually too far back. When I went inverted it held inverted without any down elev pressure. I moved the battery pack to behind the tank. I only use a 6oz tank. I get about 7-8 minutes at full throttle, but most flights last 13 minutes because the SE flies very slowly with very little throttle. I just burst the power when I need it. I use flaperons coupled to elevator when I'm horsing around at low speeds. It seems to add 10 inches to the wingspan because it adds a lot of lift. My next mod is to add 1.5" of span to the elevators. This will mean some nice sized counterbalances on the elevators. I use a 13 x 6 APC, but have been experimenting with a 12 x 8 APC. It seems to give more torque and higher prop blast speeds during the hover/torque roll (attempted torque rolls anyway). The 6lbs 3oz weight requires more power than is comfortable in a hover, but it still fun to try. I think if this could be brought in at 5lbs it would be a lot better, but it's a heck of a lot better than most sport planes. With the 13 x 6 prop vertical is unlimited. I can "s" my way up to 1000 feet and still have 40-50mph across the top. What a blast! Good luck with your SE.
