My stab is set at 0 degrees to the thrust line as per plans using a digital SMART LEVEL during construction.
Since my plane flew "hands -off" on the first flight , according to Owen Macpherson, my test pilot, I have to assume that the SMART LEVEL was an accurate tool for the job. Wing wash out was also set using this device on dowels , drilled on the O/B wing rib centerline. Worked out great . No trim tabs required.
