Thanks for the cockpit shots, Gman. Very nice! The cockpit usually determines how much I fly an aircraft.

I needed a break from the scenery work, thus I took on the F7F. Once she's released I'm back to work on the sceneries. Yes, I did get the ORBX vegetation upgrade as soon as it was released. In my view it is an absolute must and a massive upgrade for the money. Excellent value.
My libs will be individual objects i.e. trees, grasses, bushes, brush etc. that can be added anywhere via IS or other SDK tools for FSX, FSX Steam, P3D and compatible with scenery from all major developers.
Very FPS friendly with negligible impact on performance.
The attached screens illustrate a small sample of my grasses installed at my KMMH WIP scenery.

Beautiful work Gman! Im in awe

We'll need to put that together for the F7F2, and F7F3 variants. Lots of cannon, rockets on those two.

Looks superb. I can't believe how well this project has progressed.
Will there be a "small faired spinner" (as per La Patrona) model too?
No biggie, if can't be done - it's just a sweet look. Just like on the B377, L-749, Tempest II, Sea Fury ... something about faired spinners on radials ...
Interestingly, I learned from this project about the large diameters spinners featured in these screens. I had never seen those until a few months ago, and prior to commenting on them being too large, discovered that indeed, the prototype, did have them, just as shown in the screenshots. Makes me wonder how that resulting tiny ring of open surface area managed to provide adequate cooling to the engine - I suspect that the deletion of the large faired spinner had something to do with that ... speed gain (if any) was marginal against the cooling lost? Just guessing here ... but it was an interesting discovery - thanks to Milt and co., who modelled it and made me research ...

I did do a set of La Patrona “what if” spinners for the F7F1. La Patrona will be a special variant of the F7F3 with spinners, special textures and a unique second seat bubble canopy.

What I conclude from the latest-generation radials, is that they indeed used big spinners. Look at the Sea Fury, the FW190: these were high-performance, high-speed fighters.
From the side, these fighters look very streamlined, something achieved by the big spinners. Only a small gap is left between the spinner and the cowling, to allow a part of the total mass flow (that flows onto the nose) bleeding into the engine compartment, thereby cooling the engine.
Look at the Bristol Mercury and Pegasus. Between cylinders, 'guide plates' were placed to guide the air exactly alongside the cylinders to effectively cool them. But, this is still very un-streamlined, since the air has to change direction in a very unpleasant way (the basic principle of streamlines). If you determine the required air massflow to cool the engine, make a smallest possible gap to let that massflow through and make the surroundings of the gap as streamlined as possible, will result in these spinner/cowling configurations.
So, I guess the required mass flow to cool the engine, isn't that big as we expect.
Just my 2 cents as budding engineer

Regarding spinners and other fighters, the Fw190A series had a fan behind the spinner and was extremely effective at cooling. The airflow inside the cowling was directed so it actually flowed forward between the BMW's cylinders afaik. Hard to imagine but the designer was one of the best of his era.
Oh Daan, streamlined airflow is not as efficient a coolant as turbulent air, but turbulent causes more drag: the continual engineering problem of trade-off!

Regarding airflow in the cowling, I may have got my info wonky. The airflow entered the engine bay central area and flowed outwards around the cylinder heads, but the annular oil cooler just behind the spinner did have air drawn forward from there to cool the oil. There was therefore a measure of air recirculation going on, before the hot air exited the rear cowling. Now back to the bad kitty!

Thanks Tom, makes it clearer!
Gordon: if we want bombs and the like on this sweeet kitty, you'd have to model them as well and tagging them with a visibility tag. TP has models of the armament of course, but they only show up while being jettisoned or fired. I can write the background code, if you want.

The F7F-3 variant has a variety of armament modeled. What may be lacking we can surely add, I'll do some background but anyone wishing to contribute is certainly welcome.
I'll be moving on the F7F-3 as soon as we release the F7F-1...then the fun begins with cannon, missiles, bombs and the tanker.
Once I get a flying beta for the F7F-3 we can start integrating the code.
