Brief History

The Cessna Skymaster is an American twin-engine civil utility aircraft built in a push-pull configuration. Its engines are mounted in the nose and rear of its pod-style fuselage. Twin booms extend aft of the wings to the vertical stabilizers, with the rear engine between them. Wiki

Enjoy the Skymaster! I might make the O-2 Skymaster, or the military variant. Maybe before or after the Il-2. We'll see.

    @UltraLight or you could consider the elevator movement on the ground as the manipulation of the surface during the walk around, push the elevator trailing edge down, the trim tab should move up / remain neutral, push the elevator trailing edge up, the trim tab should move down / remain neutral.

    @edensk ok, however if you want to be that accurate, you might as well add a system that decreases deflection at a certain point where air resistance tends to force the surface down more.

    Thanks man I really appreciate the positive support! And yeah, the landing gear took me a while to get mostly-accurate. Very difficult. @CRJ900Pilot

    Woah, this is amazing! The shape is spot on, I had to look twice to see if the screenshots were from real life! The gear is sweet too, I can imagine that it took a while to get the angles right

    It's perfectly fine to ask. And I really do like suggestions. But I have a couple projects I want to make as of right now. @Fliegerkerlchen

    @Hedero Your generally huge, and I like your GA aircraft, so I thought I ask.

    Ehhh I don't think so. I'm huge on ga aircraft it seems. @Fliegerkerlchen

    Could you maybe do the Cessna 182RG or 172RG?

    @UltraLight use IAS squared, not just IAS

    No, I am fully aware of the functionality and physics of a trim tab, however, the only reason the entire elevator moves on trim is to allow for a trim effect to take place. The only other thing I could do is to put a small wing in the trim tab itself. But that wouldn't work in some cases. And I am also doing what BogdanX did on some of his older creations with the trim tab. You should check how they work out. I appreciate the help though. @UltraLight

    TL/DR: use this code for the elevator: Pitch + (clamp(Trim * (IAS / 200), -1, 1) / 3)

    @Hedero well, I'll explain!

    You may or may not know how trim tabs work, but you got the movements right here at least: so basically(we will be using nose up trim as an example) the small trim tab moves down, deflecting the entire elevator up, therefore pushing the tail down and nose up(I assume you know this already). HOWEVER: the full elevator actually has no connection to the trim system. It is dependent on a flow of air over the trim tab to make the elevator move into the trim nose up position.

    Hope that makes sense... here is some FT codes that may help you:
    Elevator: Pitch + (clamp(Trim * (IAS / 200), -1, 1) / 3)
    As for the wing part just use the standard trimming system; the tab rotator is good as it currently is

    Substitute the plus sign for a minus if necessary; and the 200 depending on the top speed of the aircraft in m/s. The three at the end for how dramatic your trim needs to be(trim in SP is quite dramatic for visual effect but that's fine, makes it look better)
