Hi Matt,
Thanks, I really appreciate the input. I was hoping you would chime in.
The last thing I built like this was a R.Chidgey Typhoon 2+2.
A few of us here collaborated , got some fuz mouldings (they were good/great very light and strong) and scratch built the rest loosely based on the plan.
Funny thing is, I did all the wings just like you just suggested ;increased % at the root and reduced chord and % at the tip. It would snap on a six-pence (dime) and you could have a cup of tea while it did a set of spins (if you wanted too).
I'm hoping to do likewise this time - subject to getting my hands on a suitable fuz moulding - I have a particular option in mind + a back up.

I like the flying stab idea - light too - I used them on aerobatic slope soarer's for years. So thickness should not be an issue. Considering this how thin would you go with the stab ?
This will be propelled by Brenner's contra.

Can you speak to the relationship between high point position and CG position ??

Again thank you

Brian
