Super cool design! This is the best XF-11 on the site, by far. There are a few problems though. Firstly, I'd just like to say this is constructive criticism and I mean no hard feelings. That being said, lets begin:
- It can't track straight on the runway. I would imagine this has to do with either the cockpit, or not building with 0 mass and drag parts from the beginning. That, coupled with the slow nose wheel and nothing to reduce its effect at high speed, makes it hard to keep straight on takeoff and landing.
- There are gaps, almost everywhere. Most notably on the gear doors, but there are many areas that can be smoothed out more
- Part efficiency, or lack thereof. While the custom engines and props are cool, they aren't needed. 128 parts for just the prop blades(can be done with 4) probably 400 parts for each engine (can be done with 2) , 20 parts for the exhaust pipes alone (can be done in less than 5), probably 250 parts for each roundel (can be done in maybe 50 at most), 20 parts for black lines on spoilers (can be done in 2), 400 parts for gauges you cant even see as they're behind the seat, etc...
- Smaller details are neglected. There is part of the glass canopy showing into the nose wheel well. There are hinges connected to nothing in the main gear wells. Intakes lead to nowhere. There should have been a solid black wall in there to simulate depth. There's a random fuselage hanging off the back of the left boom?
- Flight performance. It turns better than most fighters. Keep in mind this plane was bigger than the Lockheed Constellation, shown in this picture yet it turns faster than a P-51. No wonder the wings break off so easily. Speaking off, that's another not needed feature. It complicated the whole plane, and adds parts to the wing as you have to build two that are connected, rather than just one big wing.
- Paint. It's very bland. It's hard to tell from pictures as they are mostly black and white, but from the few color pictures, the plane is more of a grey/aluminum color, not white. A few ticks darker in the paint menu, and a touch more metallic would've fixed this. Also, the engine is painted white, which makes it hard to notice it. Plus its all white, so its even harder to notice the 400+ parts worth of detail
I feel bad for critiquing so much, I can only imagine how much effort you put into this build. I estimate tha

Jundroo : makes a game where people will be able to share builds
HappyFeetWhyshouldi : ok let's make a 4000 parts plane

ok so let's be serious two minutes, the build is awesome, it does look like the real plane, details are unbelievable just as the custom landing gears, spoilers, control surfaces ect....This build is for sure really REALLY good. BUT there are some flaws : first the part count (yes some people will say "blablabla it's not that bad" but it is !) I know there is a lot of details and custom parts but absolutely NO PART ECONOMY ! Which is a shame for a plane with this ammount of details, for exemple in your jauges each line is ONE part, but you can make two and up to four lines with one part...Also the tail doesn't really look like how it should where the fuselage and the vertical stabilizer meet which is unfortunate for a build of this quality. (And I'm going to say it again, so much parts is great to show what you can do, it's like a piece of art, but high part count doesn't mean good build)
However don't think that I find your build bad, it's magnificent ! Better than a lot of builds :))
