Do you know if the airbrakes actually help reduce the ground roll after landing? Being such a heavy plane, my MiG rolls "forever". Airbrakes or reverse would really be of help.

Now the stabs deflect in a proper scale fashion!
Could you please send some pics of the model with the stabs deflected pitch up and pitch down? :D
That configuration should indeed reduce the stress translated to the airframe, the stress seen by the own stab and the torque around the shaft that a servo would have to overcome. But since you didn't change the servo angle and it still actuates parallel to the airplane's longitudinal axis, that kinda spoils the mechanical advantage of having the correct scale axis.
Ideally the servo linkage should act perpendicularly to the shaft. That said, the whole thing at least should translate to a more robust construction, more scale looking and more accurate flight dynamics to the full scale jet :)

Hi
here are some pics of the stabs (maximum deflection/way to high for in flight of course). yes the servo is not positioned optimal, but the problem is the space in the tailsection, the two balllinks help a lot to keep the "pushforce" straight (see pics). For the maingeardoors i have not had a idea to make it work without "wheelscratching" them, but who knows.

Couldn't want a better image than that to see why the elevator servo loads are high on this model.
