Exactly!

About landing gear ander zero load... Real: In real 733 D1 maybe just a little bit less then D4/2, just a little bit. Lovely IXEG: It's maybe not so important, but I just noticed.

Yes, I wrote "speedbakes" because in Plane Maker we only have "speedbakes" but we know, It's about GROUND SPOILERS too) But, however, I think in this case, when we use speedbakes (speedbakes I mean flight and ground spoilers) (and especially ground spoilers), flaps Cl (and I think their Cm) should change too, because spoilers located right before flaps and when spoilers deployed we should have got airflow separation from the flaps and as result Cl and Cm of the flaps should be minimized too and as result overall Cl and Cm of the wing drops too. In anyway with logic that I described (and with my script) all comes to work just fine.

Also I noticed that Inner cylinder (pistion) on main landing gear have about 1.5 higher deflection under zero load (in flight, when landing gear not loaded). I.e. the distance that I mark with red arrow on the image below have about 1.5 times more length under zero load then we see in IXEG 737 now.

Hello! I noticed that landing gear don't deflected same way the real aircraft have. And after some research I found that flap_cl don't change when speedbrakes are deployed. But I think, from aerodynamic point of view, flap_cl should have massive drop. As a result speedbrakes are not so effective as real ones. On many videos that we can see the aircraft rapidly "drops down" on wheels immediately after touchdown and when speedbrakes come up. I have wrote a script for FlyWithLua which is fix flap_cl and flap_cm depending of speedbrakes angle deployed. I attach this one for illustration. Also I change damping constants, and deflection a little bit too, this way: I have loaded three videos if you wish to see the result: PS1: Also I've noticed that CDU and Ground Service shows stab trim settings for CG 20 and 22 — 3.6 and 3.4 respectively. But based on AFM for B737-300, stab trim settings for 18 — 22 range should be 4.75 — 4.25 respectively. PS2: I want to be a beta tester!) But anyway! Great thanks for this beautiful product!
