Slowly but surely... Basic 1/16" square balsa Stab but added very lightweight 1/32" caps and sanded to airfoil (max thickness at 25-30% to .020" (about) at trailing edge. Offset hinge line. If this "Lead Sled" is going to fly, it's going to need all the help it can get!

What a wonderful informative photograph.Soak the balsa in Helium before sealing the wood. Makes it more bouyant in flight!

Wow, I would love to see this in person! Thread for the tail surface linkages?

Just going to use carbon rod with bent wire "Z" bends on the ends. Found that using micro Heat shrink tubing and a dab of CA works great for that on small models like this. You can shrink the tubing around the wire and rod (use a soldering iron not a flame. The carbon rod will distort if heated too much. Believe me, I know! ;o) ) and this will yield a tight, but adjustable, length for fine tuning. then lock it in place with a dab of CA. These servos have linear motion so pull pull cables would add more monkey motion and I do believe I've had enough of that with this model! Phil
