You didn't say what software you are using, where you can not achieve TX input.
It sounds like you are trying to use the sims for "predictive modeling".
Most are indeed accurate enough to give you a VERY good analog of their real world counterpart.
But as with ANY simulation, you need to tweak the sim & model by first documenting the real world aircraft, then adjusting the simulated version to do EXACTLY the same thing within the constraints of the simulation.
That gives you a starting point for making changes, and seeing how those changes may affect the real world aircraft.
While this gives you a chicken and egg problem, this is how most expansive simulations operate...
e.g. for satellite orbit predictions you need an accurate model of the gravitational geode, to get that you send up a satellite and observe the perturbations in it's orbit...
You need one to get the other...
All except one sim is table driven, only FS-One purports to utilize fluid dynamics in the simulation, yet the end result is one of the LEAST realistic analogs to how the real aircraft fly.
Case in point, I have a Funtana 90 that exhibits a second order quirk. As it lands it tends to bloom up a bit just before stall.
I can't quite duplicate this in Phoenix though I can get a bit of this behavior to appear by adjusting certain parameters of the model well outside the specs of my real plane.
In Realflight I get partial representation of this behavior ( but no ground effect ) when the numbers are close spec, but I still have to adjust the model somewhat out of spec.
I couldn't get this behavior at all in Aerofly 5.7 and certainly not in FS-One.
With NO sim are you going to be able to plug in numbers and get exactly the response you expect without extensive fine tuning.

BTW: Aerofly 7.0 does NOT include an interface. You must supply your own or you can purchase one separately from them.
This is one of it's salient features, it is NOT tied to a dongle or copy protection device any more.
I have not tried the 5.7 interface with 7.0. It may work.
