Aerodynamics Question

[Terry Brox]

I agree with George, a pitch to the belly. The roll should be correctable with the right dihedral. I have seen aircraft with the stab below the thrust line cure the pitch problem. Notice the stab on the Typhoons. Chears, Terry

  You will realize an increase in belly pitch at KE and adverse roll couple, but you should be able to mix out any ill effects.
