Building the Inside end support pivot of the left wing aileron. This needs to accept an aileron torque tube to activate the aileron as per the Cabin Eagle. As I am working from Double Eagle plans, I am deducing the requirements from the Cabin Eagle wing video. At this stage the hinge is only drilled for a 1/4 bolt and will need to be drilled to fit the diameter of the torque tube (assumed to be 3/4"). At this stage neither the torque tube nor the torque tube bearings are being built or installed.
