Can you look at other aircraft developed by the same company to get a general consensus of their layouts and come up with something which would be relatively close in what it should be?

Unsure. That is a possibility though.

I think at this point with all of the research you have done so far, I would say you are the subject matter expert on this and what you determine will be the most correct anyone will be unless actual documents show up.

That's looking really good

If you could put the quote in spoilers that would be nice

The exhaust pipes looks like small jet engines

This design might have worked really good as a jet attack aircraft

So I’ve realized that I should do the low poly cockpit first or else I’ll remain burnt out and never get the model to a shippable state. So… this will be fun I guess… lol at least more so than the high poly cockpit. I need to finish the central gear well as well.

[PickleJarOfDeath 1,496]

Here is the current progress on the cockpit. I am trying to get basic details throughout the cockpit done. The low poly cockpit is in progress. I will not put time into the high poly cockpit until I see that I can get the model shipped to the game.

Any ETA on when this comes to the game?

All I can say is probably this year.

 

I want to make sure I at least have:

 

1. anchor points for the mechanisms in the central gear well

2. a completed and basic 3rd person cockpit

3. high poly gauges for the 1st person placeholder cockpit

4. fully redone uv map

5. textures

 

After that I have to break up the model into it's modules and set up the animations. I need to have the damage model set up as well as the lower poly models for far out distances. The naming conventions also need to be set to match War Thunder vehicle object naming conventions. After that I think the emitters are next. There are probably other things missing but I need to get it to a state that is equivalent to a finished and functioning model of a War Thunder aircraft. Once that is done I would like to develop a flight model for it so I could import it into the game for a user mission. That is then when my work is done and the project is left to the discretion of the developers.

can we get a update on this? i have my GE saved up

I gave one on Friday... Do you mean a visual update? The only thing that has changed is the propellers. Aside from that I have been reworking the mesh of the nacelles which is not a very visible change despite how much work goes into that. The outboard air scoop has been updated as well but not much to really show in terms of updates to the model.

The Moonbat is one of the beautiful what ifs, and I'm very happy there is someone talented working on bringing it to our computer screens, chiming in to say the model looks awesome and I can't wait to fly it out and kill some bombers. 

 

The shape being so aerodynamic, I'm very curious as to its vertical capabilities, especially since it's already a fairly heavy air craft if I'm not mistaken. I suppose powerplant determines quite a bit about climb rate, but diving it must have been a beast.

I'm glad to hear you are excited!

 

As for the climb rate it should be listed on the stat card according to military power (@ 1600 hp) as 15.05 m/s while the max climb would be 19.76 m/s on WEP (@ 2100 hp). This is assuming they implement the XP-67 with its engines as they were when they finished development. The top speed could be at or near the estimated 760 km/h. The max dive speed is something for which I only have one clue. The listed number for terminal velocity is 974 km/h. That is absolutely insane. However, this is theoretical.

Well, the critical Mach number, from which is the maximum safe velocity derived, is a matter of airframe aerodynamics. 974 km/h is high for WWII design, but it's been actually exceeded by Spitfire. I'd say it's possible, but since it was probably written during WWII when the knowledge of transsonic effects was limited, the actual critical Mach was probably a bit lower.

The aerofoil was basically the same as the P-51 but made thicker relative to chord length by about 1-3% iirc. I don't know if that is really helpful to get an estimate for the max dive speed but that could help with a ballpark estimate.

I figured that she would be a beast in a dive, whether she her engines had their real-life performance or not. 

 

Just imagining the play style I think she will be right up my alley. 

 

I personally would rather have the 20mms than the 37mms I'm a big fan of the P-39 and my experience with the 37s is mixed.

The dive would be probably near 900 km/h like the P-51s but who knows where it would really sit.

 

The plane would have an impeccable turn rate at 500 km/h with a load factor of 8. That is a great deal of flexibility for combat especially if it gets the upgraded engines.
 

lol I prefer the meme potential thank you very much! I think this will be a better experience because you don’t get cluttered and false feedback of 2 very different guns and getting repeated hits that all end up being 7.62 or 12.7 mm guns. You can just focus on the M4 cannons with the 610 m/s muzzle velocity. The aforementioned superior turn rate of the XP-67 should make aiming these cannons easier.

Here is the animation for the model. I no longer have the model set up for rendering in Arnold Renderer. I have a few things that need to be modeled but the model is mostly done. I'll be trying to import into the game soon so I can get to work on testing the whole thing.

[Skiraider 4]

Nice, I've been following this project for quite a time now and I hope you'll succeed introducing this plane in war thunder. If that happens it will surely be my favorite fighter in game.

All nice aside from the fact that I now have to redo all the animations in 3DS Max because the import no longer works properly. I also have to do the UV mapping so... That part won't be fun. I wouldn't mind on any other model but the XP-67 is tough to UV map.
