Unofficial balancing.

Unlike the other control surfaces, the aileron on the Sonex has to be balanced. (After painting if it was to be painted).

Just sitting on the table it just flops over.  These pictures show the aileron in a balancing jig.  This is not the suggested method, the plans call for suspending the aileron from two thin wires by the hinge pin.

      I attached the other hinge half, and because there was no binding of the hinge at all, I clamped that half to a piece of angle as if it was the wing.  This is just a test and I will balance it as Sonex suggests although I think this aileron could be balanced in this jig just fine.

          To get it to balance here, I added weight to the aileron instead of drilling lightening holes in the lead.  The weight is a bunch of napkins and a piece of scrap aluminum that weight 73 grams.  Since the cg of the napkins etc. has an arm length of about 8”, I will need to remove approximately 145 grams of lead from the plans indicated location which has an arm length of about 4”
