water physics definitely need a lot of love… but a long list has been raised and the devs have it
was testing the default C172 this afternoon to compare to a plane in testing, and the C172 floats is actually uncontrollable on the water with any kind of wind. had 8kts today and you could not turn with water rudders down, and it weather vanes like crazy…
but to stay on topic 
100% sure I’ll never fly the Spirit of St Louis or the Wright Flyer ( maybe once as a novetly )
Spruce Goose - probably 1 flight just to see what it’s like - but you’d need 2 throttle quads to support it
I’m super glad the DC-3 and A310 are there - crowd pleasers for sure, but probably won’t fly them much myself…
Very curious about the Jenny - that could be fun for VR barnstorming
Grumman Goose will hopefully be fun - but ^^ water physics.
Looking forward to gliders - hope the feature set is good, and eventually you can tow in MP
I love helicopters and am cautiously optimistic - but I think it will take a few updates to nail it.
Beaver will be good fun for sure
