With the stabs off the clamps, everything is now straight. added all the bottom half ribs and LE.
For power, I'll use 2 x 30cc engines. With the design of the plane around 2 x .90 glow engines I really don't want to see the H-stab fail. So, I've added 2 lengths of carbon fiber rod (1/32 x 1/8) to the bottom of the spar. These will be under the sheeting. The CF strips will also discourage any future warp.
