Al,

I would install it as usual then adjust later. The type and pitch of prop will also cause this issue so of you are planning on changing the prop after the engine breaks in them you can either added the thrust now or wait until you change the prop.

Maybe I should explain why I have so much up thrust. When I was using a PT models 22x8 it would pull to the gear and left on uplines. I added one degree of each (right and up thrust) which was dead on for my needs. I then swapped out to a Vess 22A and since this prop moves much more air I needed more up thrust as it started pulling to the gear again so I added another washer to the bottom mounts. Now it goes straight up again and will not be a problem since I'm staying with the Vess prop

I am also one who will run though a trim chart from the top down. Because of this my mixes are very small. I only have 3% of up elevator at 3D deflection and now 1% of opposite aileron. Before I changed the CG, wing incedence and now the thrust angles, I had something like 10% up and no aileron.

I have roughly 3% down elevator mixed into the last 2 clicks of the throttle to get nice straight downline and just 2 clicks of aileron trim and no elevator trim.

Yep, call me anal, yep call me nuts, but I have a very predictable plane that does exactly what I want and how I want it. I do this to all my planes and those that I let fly them love them

BTW, you do not need flaps on this plane to slow it down. At just under 14lbs on mine, it floats and floats and floats....I had to lower the idle to land this thing with the Vess prop
