Extreme crabbing with any speed change.

[Gunfreak]

I assume after 1+ years of fine tuning the flight model, this is correct. 

But it feels very odd. As even a shallow dive giving moderat speed increase causes the aircraft to go extreme out of trim. And you end up flying almost sideways and making it very hard to hit anything on the ground with guns, no matter how much I try and compensate with rudder or trim.

rudder trim........mine flies pretty good trimmed out

I continuously work the rudder trim. But even a 5knot speed change changes the rudder trim completely. And if you add 50-100 knots like in a shallow dive the aircraft goes sideways not matter how much trim or rudder i do.

This is common behavior for all the warbirds, though definitely more pronounced in the Corsair than the P-47 for example. From what I've read it seems that's historically accurate for the Corsair as it had a little more relaxed static stability than other planes. It takes fine tuning your joystick/rudder curves and being very active/preemptive on your rudder use anytime you increase or decrease power or enter a dive or climb. The slower you are the more it affects the plane, making carrier landings...interesting. I suspect it's fairly accurate based on some IRL landing/takeoff mishaps I've seen online from WWII footage.

As you've noted, having easy access to all three trim axis' is CRUCIAL in this plane (and all the US Warbirds imo).

The curves I've settled on for now are:

Pitch 4 deadzone, 100 x sat, 80 y sat, 15 curve

Roll 4 deadzone, 100 x sat, 100 y sat, 15 curve

Rudder 4 deadzone, 100 x sat, 80 y sat, 15 curve

 

Hope this helps.

If every speed and/or power change does not get the aircraft out of trim, it isn’t modeled correctly.

 

It is that simple.
 

Every Warbird should require constant control input changes and subsequent re-trimming when changing speed and/or power.

That's not what I'm talking about. I'm talking about the aircraft flying more or less sideways and no trim or rudder input can change that.

Feel free to upload a track showcasing it.

If you are the only one experiencing this, the problem is going to be in your control setup. You aren't getting full control deflection. If the controls indicator is available in the Corsair, put it up and see what your rudder deflection is when this problem occurs.

Well, upload a track with this behavior occurring.
