Jetworks Aileron / Elevon Hinge.
Gives a strong and smooth hinge, with a combined control horn that eliminates all slop / looseness, giving precise control and dependability. Once you use this hinge you won’t go back!!
Simply trim away the depron and glue the blocks in the slot with epoxy. (use a narrow piece of masking tape to prevent epoxy getting near the hinge).
Have two hinge pins facing outboard and one inboard to ‘lock’ the aileron/elevon in place.
Print with 100% infill.
