Hey Charles

Nice subject, always liked the Avio jet C-101

My F-4 (Jet Legend) has had two engine setups.

1. Twin about 8 degrees. No pitchup at full throttle
2. Single about 4 degrees slight pitchup at full throttle

Enrique and Pete have some great suggestions for thrust lines and wing incidence.

My thoughts on incidence washout (I have designed a couple of airplanes and have flown since 1976, but no scratch built jets.... well one F-18 df that had one take off and no landing . So take my suggestions as that sugesstions)

I would guess that most fast aircraft of this type would have around .5 to 1 degree of incidence. Of course it really depends on the airfoil, and how much incedence you will need on the elevator. Also this will effect your fuselage angle during flight so if you go with a too low incidence you fuselage will be nose up during flight and causing drag.

The wing thickness looks pretty good and it is straight so you might get away without washout, which makes for better aerobatics, but more critical landings.

Good luck and please post your progress!!
