Don,
The final weight before fuel is right on 10.5 lb. (10 lb 8 oz)
The controls are still the same as when I originally re-ironed them at the beginning of the build. If you have seen me wring out a plane for snaps you would know that I really give an airplane no respect at all.
Actually did the reverse avalanche first and then the FAI F-07 Finals double that has a negative snap on the bottom. No issues at all. The elevatrors are not that big, nor are they counter balanced so the stress is not that high IMHO.
To flutter there really would need to be a poor linkage or soft horn installation. With an 8311 SA on each elvator half it reduces the chances of flutter. You know we/they used to fly a lot faster with open structures in the pre-turnround days. I can, however, understand the concern about a covered-open-structure elevator, but so far none of them have miss-behaved even when flown S&L at full speed.
I am always looking for good options below $500. If you are looking at options above that then you are way past my input
Regards,
Eric - who is hoping that the local lightning storm does not kill his high-speed connection[&:]

Eric, thanks for all the build info and test flight report. A couple of quick questions and sorry if I missed this info in your post.
Finals weight?
Any concerns with the elevator/aileron construction (lack of sheeting and stiffness)? I had the chance to examine an Evolution yesterday and was surprised to see the elev and ail construction with no sheeting. They were flimsy and easily twisted with gentle twisting by hand. Did you experience any mushiness or flutter symptoms during flight? Did you really wring it out with reverse avalanche type snaps and higher speed maneuvers or is that to come in future reports?
Hopefully this plane will be a choice for people that are looking for a lower cost 2M type plane for pattern use.
Thx, Woodie (Don Atwood)
