Installed aileron trim tab.Used snips and a file to shape the cut outs, Everything lined up well with very tight tolerances. There were no instructions (that I could find) on where to locate the servo - I positioned it so that the actuator arm was in the centre of the tab,
The plans called for the edge of the inspection hole cutout to be 149mm from the trim tab itself. This distance was reduced to 140mm otherwise the inspection hole cover plate was too close to the front edge of the aileron!!
