No, the trailing edge is simply vibrating up and down but no more than the vibration I feel at the control stick.  Although the vibration on the control stick seems to be greater than vibration I feel on the rest of the airframe (i.e. comparing it to when I touch the canopy or the instrument panel). Boy, this sucks though!  There has got to be a solution to this thing.  So, after adding a little more weight and dipping the main wing skin trailing edge area to align perfectly with the ailerons, VIBRATION IS STILL THERE!!!  No effect, NADA, Zero, ZIPPO!!!!  Still only on the left aileron though.  The right aileron is solid as can be and this is the reason I feel that it may NOT be JUST engine vibration but maybe a combination of both (i.e. aerodynamic & engine induced).  Ok, so that fix didn't work.  I made another observation regarding yesterday's flight; the left aileron is slightly down (1/4-inches??) and the right aileron is slight up during cruise.  This seems to indicate a left heavy wing since the left aileron (down) is lifting the left wing to keep it level.  So, before I left the airport yesterday, I adjusted the LEFT flap  rod end and extended it a turn.  Now the flap will carry the left wing and I am hoping to see both left and right ailerons on equal positions and probably equal loading.  With my luck on this problem, both will be vibrating on the next flight<G>.

The saga continues, more after the next flight....
