- Moved the CG forward about 0.5" ahead of neutral point. This seemed to help quite a bit- the wing was a lot more stable and easier to control. It could probably stand to get moved forward slightly more.
- Increased the aileron dual rate to 50%. Both aileron and elevator are currently at 70% expo.
I managed to fly a couple laps of the field, then I was disoriented or something and hooked a wingtip on the snow. The landing, while spectacular, didn't do as much damage as I would have thought. The winglet that didn't break last flight came off, and a new crack opened up near the motor mount but that's it. Also, one of the set screws in the motor mount fell out so I'll have to find something to replace it with. Not too bad. I also flew it with the 1050 mAh 3s battery- which may have helped keep the speed down and things under control.
For the "real" wing I'll definitely be doing a couple things differently:
1) extend both spars across wing midline to strengthen that foam joint- it's just not strong enough now and breaks during every hard landing
2) add some kind of small fuselage extending forward of the wing leading edge, and have a long battery box to allow easy adjustment of the cg.
