Christian,
thanks for the info. The CAD re-design looked a little hefty. I think this bird can be built to 10-11 lbs using 3/16" sides, a 1/32" lightened doubler and a 3/32" skinned deck rather than using the block balsa. The nose top can be done in a "keeled and glassed foam".
Still, at 12.5 lbs, it should be ok in terms of loading (I think it is around 1000 squares). I suspect a 120 AX might be needed for thrills but the 95 should fly it nicely and in TOC style.
