I have a Stinger 120 with the wing built according to plans. That is, the leading edge has a radius of maybe 1/8" - 3/16". That's pretty small next to a 18" chord and a thicknes that is over 2".

Flies great, lands slow. Thing is, I want to be able to have better control over the stall as I transition to hovering and hopefully other things (harrier, etc) down the road. Right now, as it gets the nose up, I get wing rock. A rounder LE might help, but inducing separation near the mid-span with stall strips might work as well. I've heard some say that sharper LE is the key and some say that blunter, and some say that a tapered radius works. Without really knowing how the wing stall progresses on this wing, it's hard to tell which approach is right for the Stinger.

I'll probably start experimenting with stall strips soon, by taping 1/4 balsa tri to a small section of the LE.

Comments..?
