There are ways to determine your engine thrust angle needs and your wing incidence requirements.
To trim the plane and run it wide open throttle, trim it out, then chop the throttle.... See what it does? If the plane tries to immediately climb, you had too much down thrust. And, naturally, the reverse of this is true.
If you get your engine thrust correct and it tries to climb at higher speeds, you may have too much positive wing incidence.
Looks like you've done some homework already to have the outward thrust on the engines.
Enjoy,
