Hi Charles, if you copy the wing incidence of the full size casa , as well the turbine thrust line it will be ok.

This airframe has the thrust line on the low side of the fuselage profile. If this thrust line is set parallel to the airplane fuselage it would tend to pitch up at full thrust .. so aircraft designers tilt the exhaust down canceling this effect and even adding a little more so in case a novice jet pilot gets near a stall and then go to full power the airplane tends to pitch down helping to get out of this potentially dangerous situation.

Something from 5 to 10 degrees would be tipical for a plane like this.. but as I said above, just copy the full size one and you are going to do fine.
