wonder how AEFS4 copes with the aerodynamics of negative flap setting.
It did a rather acceptable work in AEFS2.
In modern gliders the flaps / flaperons are used to optimize lift & drag at higher speeds.
Apparently and through the AEFS Wiki it appears that negative flap settings aren't available in the TMD files (?) although they are visually represented, and their effects looked quite reasonably modelled in AEFS2.
Does AEFS4 accept and aerodynamically represent the effects of negative flap settings ? How can it done in the TMD files ?
