Libelle flies on a warm winter afternoon, Mormon Lake Overlook
We are in a February thaw... lots of sunshine and relatively warm temperatures. This past Monday I took advantage of a nice 12-14 W to WSW breeze and took Libelle for a spin. It was a wonderful floaty day. Here is a short clip (1:30):
Video was shot using my GoPro2 strapped to the back of the transmitter (Tran-Cam) and edited on our new Macbook Pro using iMovie. I love the computer; but will have to upgrade the software. Music is from a (new to me) instrumental album, Speechless (2005), by Bruce Cockburn.

Thanks for the comments guys. It was a perfect day for Libelle... ideal slope lift and solid thermals drifting through.
She is getting a bit beat up, so I think I will get a new one, for Weaselfest, and start doing some mods on this one. I have already increased the rudder surface by about 3/4" using some transparent tape. If you have eagle eyes you may have noticed it on the video. Next mod will be a reduced dihedral wing and then a pull-pull mad stab. I am not sure how to do it yet... not much room in the pod for a large elevator horn/pulley.
@thenickdude: My throws are close to Michael's suggested high rates. I have a few millimeters more aileron throw and down elevator. I am flying 100% throws using the first hole on the pod servo horns and second hole on the aileron servo horns (HS35's). I am using snap flaps all the time... a bit more reflex than camber.
I try to fly as smooth as I can and with as much speed as possible. This really keeps the roll rate up. I also try to stay in the best possible lift on the slope (i.e. "juicy" spots, mini bowls, etc) and use favorable shifts and gusts was they appear. I learned this early on watching and flying with Surfimp and Michael R. at Weaselfests. Those guys, and many other locals, really know how to work the Bluffs. I do have full throw 4th axis control on the centered throttle stick which is useful for some radical maneuvers... like really tight loops, brakes, "instant" recoveries, etc.
One other note... I am finding that Libelle likes to flat spin best with little to no wing camber/reflex. The added rudder surface seems to help that as well.
