Hi Keith,

When I set up my incidences I started by setting up the fuselage like this.

The F1 sits at 90% to the trust line, the thrust line is 0%. If you pack the rear of the fuselage up so that the chin cowl line is level (0%) you then have the correct attitude for the fuselage flight angle. On mine when set up this way, the stab spar tube & anti-rotation pin marks ( indents ) where in the correct place to achieve 0% incidence on the stabs. Whether or not that relates to a 33.5mm packer under the fin post being correct, I'm not sure. My advise would be to assume nothing until checked! MTK was right though in as much as the main wing anti-rotation pin indents may not be in the right place, mine certainly were not ( worked out to be -1.5 degrees incidence [:@] ). Although these models all pop out of the same mold, that dosen't mean that they are all exactly the same, small differences make a big deal!
I can confirm though that the method I've chosen worked for me and the model tracked perfectly in all attitudes, including knife edge! It should also be noted that the 2 degrees of side thrust stated in the manual wasn't enough on mine. 3.5 degrees is the sweet spot using YS 140lm 15 x 12 APC & Wildcat 3DLV 30% fuel.
Check www.composite-arf.co.uk, Mark has started a thread on there which shows the method with pictures!!!!!!!!!!!
Hope this helps,

Andy.
