What Ed said.........

I've just slapped together a $40 chinese ARF that looked like they actually meant to have dihedral in the sucker but the plant workers did it upside down. The first version of the sucker I saw had about 1degree anhedral. When I got my kit, it's wing joiner was so undersize, I could have put almost any "hedral" into the wing I wanted. The inside ribs were thick, spongy "liteply" and set up for about 1degree anhedral, so I ran them through the sander and came out with about 2.5degrees in the wing.

It's the 1st anhedral I've flown. It has a lot less roll couple in knife edge, but part of that is because the rudder has about the area you'd expect in a 1/2A trainer. And the sucker won't actually do a knife edge and maintain altitude. Actually, maybe it will, but so far the workload to fly the sucker sorta masks what it might be able to do after it's trimmed out better.

Anhedral will surely turn some heads at your flying field. I flew the other day in conditions that, around here, keep most people at home. It was windy and cold. When I pulled up at the parking area, I noticed three guys I've never seen before. They obviously were good flyers. Two of them were dinking around the sky with that .40 size Hobbico twin, swapping the TX back and forth. The other guy looked at my anhedral wing when I laid it on the ground and went back for the fuselage. When I walked up, he asked if I'd flown "that wing" yet. Then he asked why I had the servo mounted on top of the wing. chuckle..... All three of them could fly really good, but this guy hadn't ever seen anhedral and none of them knew the term.
