Because you can't use the stab as a reference you need to create a datum line - canopy flange or just sit the fuse in the flying attitude you want. Then set the wing incidence to your required + 0.7 deg to this datum line. In my case I have 0.5 deg down thrust to the datum. Set the all moving stab about 0.1 deg less positive than the wing ie +0.6 deg. On the first flight use "elevator" trim to get level flight. The first flight is the tricky one if the stab is wildly out of trim. My experience is that the stab usually ends up between 0.6 and 0.8 deg less than the wing incidence. This gets the stab incidence in the ballpark, then use wing incidence changes and CoG movement to achieve straight up lines, knife edges etc. as you would normally. Re trim "elevator" for hands off level flight each time you make a change.
