something divinely sexy about the berkut

black flying beauty

Russians have only one S-37 in service

I'm aware

A few more in hangars, but those are in various states of disassembled

You can actually rent S-37

Be it for a leisure ride or for science

The 37 was a testing model for other technology that was going into their next generation fighters

It is not cheap, obviously

The 40 series, in this case

And "rent" means you will ride in the back seat and won't touch anything

Funny enoufh NASA rented S-37 a few times via a subsidiaries for research purposes

You can say cold war is truly over

I want to build an RC model of the X-02 Wyvern

Complete with switchblade wings

There are plans to build it online

Be sure to pay attention to carbon fiber reinforcement rods, because the wings will twist off and break if you won't reinforce them enough

lol

Definitely the reason why a real plane doesn't have switchblade wings

They'd definitely just rip off in a high g maneuver

someone make the X-49 Nightraven in rc form

Movable wings offer little advantage to justify the added weight and complexity

The F-14 seems pretty good

It all can be solved with a compromise shape that does good enough at slow speeds and is excellent at the operating range

Though the F-14 only has Variable Sweep wings, not switchblade

to fit more on an aircraft carrier

or at all

Ew

that thing flies more efficiently than your usual plane though

It's sort of a biplane

lack of wingtip vortecies makes the laminar flow continuous

But uglier

How would that respond to crosswinds

You've basically got two giant rudders on the sides of the plane
