AK, that would be awesome if in fact that is what they were able to do with these aircraft models!
Re-watching the clip again, I've also noticed now that both the Strega and Voodoo models are indeed individually separate, with each having their own, correct to reality, uniquely designed extended/lengthened rear wing/fuselage fillets (airflow distributors), which again is unprecedented and absolutely fantastic to see the level of attention to detail. On Strega, they extend back all the way to the tail cone/fuselage production break. Also, in the shot showing Voodoo and Miss America flying by, although still unclear, it sure seems like they have modeled Voodoo's re-manufactured radiator scoop intake, which tapers forward more than the stock intake (Strega has a similar mod). This section on the real Voodoo is made from carbon fiber, as are the cowl formers and cowl panels. As I mentioned earlier, I'm really curious to see if they have the Joe Clark/Aviation Partners modified upper wing airfoil depicted on Voodoo as well (added prior to Steve Hinton Jr. setting the speed record a few years back) - I don't doubt it, since modeling that would be very simple compared to so many of the other more complex details they have clearly depicted very well.
In order to properly depict the Mustang's hydraulic system, I imagine there will be new code added as well (hopefully so). I'm really looking forward to seeing what kind of a challenge it is to fly Voodoo and Strega, since they have such reduced visibility out of the cockpit (canopies just big enough to barely wrap around the pilot's helmeted head). The most highly modified Reno air racers over the decades have never been flown much, but usually just in the lead-up to and during the races, since so often the big modifications make them unpleasant to fly/not the kind of airplane you want to fly every weekend. I remember hearing about 'Rare Bear' in particular, and how it is never a good experience to fly because of all of the changes made to it for speed (where as a stock Bearcat is a favorite among pilots who have flown them). Over the years, some of the owners of the more stock Mustang racers will put modified canopies, radiator intakes and/or wing tips on them for the races, and then switch back to stock parts when flying the aircraft the rest of the year, and some leave them just as is, fully stock in and out of racing. There is also of course those who put racing-modified Merlins in them, just for the races, and others that continue to run stock (which won't get you to the gold race, but can win you the bronze and silver races). The fuel available at Reno is 160-octane, and this can be increased with additives up to 170-175 octane, which allows for the far higher power output/manifold pressures than normal (normal fuel for these engines today, at your everyday airport, is of course 100LL, which won't even allow a Merlin to run at max wartime/military power - fuel used during WWII was 130-octane and later 150-octane introduced in 1944, which cleared the way for 85-in MP WEP).
BTW, since we already have a Mk.IX Spitfire from FlyingIron, I thought it worth mentioning that Warren Pietsch took the Mk.IX Spitfire MK959 around the course in 2017, but of course didn't push it, placing last in the bronze race with an average speed of 270 mph (the entire bronze race that year was made up of stock warbirds from the Texas Flying Legends Museum, which are now all part of the Dakota Territory Air Museum). I've been meaning to do a repaint of that aircraft too, and I could very easily include a version with the the race #84 decals applied to it, as it had at Reno that year.
