This is half the center section of the X RES - a 2 meter, hi-start, rudder, elevator, spoiler plane. Very simple but a gas to fly. I should come in around 13.5 to 14 ounces. A bit of a challenge as all the directions are in German and it goes together totally differently than the last glider I built of this type. There is no carbon fiber in this one - its all wood, either balsa, ply, or birch. I'll use mostly CA on it but I'll also use some aliphatic resin (carpenters glue). Hopefully I'll have most of the center section done tomorrow.
