I assume the rudder is parallel to the wing & stab ribs & not the tail boom. Is that correct? If that is true, then the reason for offsetting the tail boom would seem to be to induce a left turn, along with the stab tilt shown on the plans. What would be the trim/performance difference between this layout & one with no tail boom offset (I.E. boom in line with the motor stick), except that there would not be any rudder contribution to the turn & the wing and stab would not be parallel?

If you're confused about the posts being on opposite sides of the MS you can see that on F1L-09 in the HPA plan gallery. The idea is to turn the MS for left thrust instead of turning the bearing and putting side loads on the prop shaft. You have to offset the boom in the opposite direction in order to keep the desired alignment between the wing and stab. It makes for funny looking models. (that win contests).

I do not get it? Could someone draw me a picture?
