- With the fuselaje level to 0° on the canopy rail, the elevator are - 1° with the adjuster full positive, we can't move the elevator to + 0.2° to give it the +0.7° compared to the wings.

- To setup the wing at -0.5° the wings incidence adjuster are complete full up.

- With the fuselage at 0° the engine is -2.5° down.

Maybe the canopy rail shape is a little different form yours, how can we determine the exact thrust line of tnis model ???

Hey Fernando... You cannot determine the EXACT thrust line with how the plane was molded. I don't think the mold was changed other than when the new version was built with the wing tube instead of the wing spars.

I would still keep the wings/stabs where you are now & try it there... You will definitely have to put in up thrust in the engine... As you have it now, when you pull to vertical, the airplane will want to pitch to the belly & you will have to also put in a LOT of up elevator mix with rudder input. Right now, I have (on low rates) 5% up ele mix with right rudder & 4% up ele with left rudder.

Let me know what you experience.
