Some progress...

I went with the cf re-enforcement as I only used strips .007 thick by 1/4" sandwiched one on each side. the cf weighed about 3 grams total...

I lightend the stab where I could. I added a 3/16" square of bass wood on the trailing spar for added strength. The cf re-enforced stab is crazy strong. RevyMaxx can confirm how tough and the weight is only .3 oz more than his non-cf stab. Worth while I think...

With the fin I used the toughtest 3/16" * 5/16 from the kit laminated to 3/16" square bass to toughen it up more for the main spar. The rest is light soft stuff. The fin is tought like nails. Should stand up to massive abuse.

If any one is interested here is my final sanded weights:

I am using a digital food scale so it is quite acurate but the oz side only shows to the first digit after the decimal so...

Stab - 68 grams / 2.4 oz
Elevator Halves (both together) - 28 grams / .9 oz
Fin - 29 grams / 1.0 oz
Rudder - 26 grams / .9 oz
