What, only one spare fuselage? Good thing your Thunderstreak apparently already crashed in your backyard, cuz it had a tendency to not be very good :P
Like the Thunderjet, the Thunderstreak excelled at cruise and had predictable handling characteristics within its performance envelope. Like its predecessor, it also suffered from accelerated stall pitch-up and potential resulting separation of wings from the airplane. In addition, spins in the F-84F were practically unrecoverable and ejection was the only recourse below 10,000 feet (3,000 m).

Good luck with your future endeavours.
X-USAF fighter fuselage don't grow on trees, so you have to buy what you can find in mostly complete form. Can't be picky with what is out there. Anything current gets 4x4" shredded at end of life, so you have to go back in history a bit in order to own a real fighter cockpit. There have been very few fighters that fly like a Toyota drives. Everything out there has flight characteristics of some sort that are undesirable. They're not an arcade video game. :wink:
