Fitted inboard aileron torque tube horns to both wings. After adjusting bolt so that the torque tube doesn't bind I added a 3/16 ally rivet to stop excessive play where the horn slides inside the tube. Positioned the rivet so that it should be able to be drilled out if horn needs to be removed at a future date.

taped in position so not to intefere with fabric covering
