Ailerons and Elevator

The first step is to make all of the ribs . Here Jerry Nolan is carefully making the aileron ribs. Note the rubber bands to hold the ribs caps and corrugated ribs together. The epoxy is mixed with microballoons to make a stiff mixture. Make sure you sand the edges of the rib material before gluing.

Jim Setting up the trailing edge on the aileron spar. Note the stepped down area for the adverse yaw damper. Make sure the spar is straight.

Gluing the gusset to the aileron trailing edge and aileron frame. use a cabosil mixture on this joint top fill any rough areas adn avoid the epoxy running out and leaving a poor bond.

With the fiberglass spar of the elevator clamped secure and made level, epoxy on the trailing edge. Fit the ribs in their proper location then epoxy.Use 5 minute epoxy to spot the ribs. When everything is together use fiberglass cloth on the spar to rib joints and then epoxy on gussets.

Note the use of the small spring clamps to hold everything in place

Jim finshing off the elevator, note the gussets at each rib joint. One can smooth down the edges of the gussets with a smll amount of micor so the fabic covering will lie better.

This is a view of the hinge block mounted in the aileron spar.

Align the hinge blocks with a string so they line up both horizontally and vertically. Add fiberglass cloth if they do not align in height. Mark the blocks with a marker. Hinges mount in the hole in the center about 2 cm from the top edge on the ailerons.
