I don't know for sure what the incidence is because I have only the couple of Robart incidence meters which don't have the resolution to measure, and I have no faith at all in the table top flatness or the airframe straightness (complete lack thereof, actually!). BTW I didn't mention that it is a Focus II ARF, which I often describe as having been assembled at the factory on a Friday afternoon after a 9-Mimosa lunch. It took a LOT of work, guesswork and some luck to get the wings, stab and fin to square up.

So without an absolute baseline, measuring 0.5 deg isn't a realistic proposition. Therefore, I will just try things one at a time and see what happens.
