WWII aircraft are generally 2-3 years to make. This depends on info and such. Most of the time they are done 1 at a time, with some overlap at the beginning and the end. Also, dont think ED's WWII aircraft dudes are sitting idle either.

I think BuzzU is just a bit irritated on the lack of the official news regarding the P-47 development. All I want is the current model to set as my wallpaper .

If we need more wind tunnel data on the P-47 for its completion wouldn't it have been found by now? So what is ED doing to compensate for the lack of wind tunnel data?

Yes, i'd fly the P-47 exclusively when it shows up. So, i'm a bit anxious for it. Any kind of news would be welcome.

ED has other ways of getting what they need, might just take a little longer, but work continues.

4 years and counting. TC

yes why dont you just casually ignore the time it takes to do problematic things like finding the p-47 aerodynamic data

Since you are one of the select few who know's what they need to finish the project,I think you should let them know and maybe they can get the job finished. Not to linger on this but like you and your comment, I also have comments that express my feeling about this > 4 year and counting project. TC

They have stated the issues for the delays. And I doubt the P-47 has 4 years of work into it, besides efforts to obtain the data they need.

Surely a prop airplane's FM has to be more complex than a jet's FM of the same level of fidelity? You've got things like torque, gyroscopic effect, propwash, and P-factor to deal with.

Well, yes and no. It's the same PFM system when we're talking DCS.

AFAIK ED's PFM is a suite of tools and code dealing with the forces on an object. Every new plane feature they build adds to it (P-51 added prop wash handling, F-15 added supersonic airflow handling etc...).

The PFM takes inputs and generates output.

Eg, The code that governs airflow hitting the plane and its effects is likely the same for all PFM aircraft.
The airflow itself (input) might be different (ie, in level flight: straightish for jets, disturbed with added rotational elements for props) which is going to cause different output, but the fidelity is in the system dealing with the inputs and how it applies them.

Same probably applies to the code dealing with engine forces. Takes in dynamic inputs like airflow, aoa, fuel flow etc... along with static input like location, mountings, engine type, blade size, prop width etc... and generates outputs to apply to the airfame.
The underlying model will be the same (same fidelity), just a lot of params change between prop and jet engines, resulting in very different outputs.

I'd love Yo-Yo to chime in on this, but I'd surprised if I'm far off the mark.
