FAR HELP NEEDED!!! X-20 DYNA SOAR

[kerbarara]

I tried to build an X-20 Dyna Soar inspired reentry glider that hopefully can handle a splash down. With the reduced part count of the beginning of the game.

The first one really looked like it, but I lost control and began spiraling out of control even from SAS and reaction wheel (I even cheated electricity to see if it'd make a difference). Even with Deadly Reentry, the plane survived but had to activate emergency parachutes.

This one kind of works with reaction wheel enabled and FAR assistance. But once it really is in atmosphere, I pretty much rotate again.

Can anyone suggest a better design, or help me figure out how to build a stable reentry vehicle? I don't have that many parts at the moment or a grasp at FAR, but would like to get some space tourism going.

It flies better, up until the roll all around and lose control at 20 km, mach 2 part.

Do you even have any pitch or roll controls? I can't see properly, but I don't think you do. I'd really not rely on reaction wheels for directional control under FAR when you're hypersonic.

This was a little craft I built for someone else, which can reach orbit on top of a single SRB - this is along the lines of the minimum you need in terms of wing & control surface.

You obviously don't need Mk2 parts.

I GOT IT!!

It's not much in terms of functionality. The reentry vehicle is pretty ok from LEO though. More capability can come later in service modules with higher tech levels.

If you angled the vertical fins you could use them for pitch and roll control too.

Kraken ate my reply.

It makes it unstable during reentry. It's not really needed, perhaps would help when landing to use the vertical as spoilers.

 

And the vertical are angled already, to better fit the fairing.
