Request General!

I've been noticing a slight influx in request posts lately, so I thought I might make a thread to localize them.

 

Also, I'm in need of a MK2/1 VTOL SSTO with some cargo capacity and somewhat simple ascent profile.

Here you are. https://kerbalx.com/stardog573/you-name-it

Problem is, this can lift only small weight to low orbit because...

VTOL -> need additional engines -> increase weight

simple ascent profile -> need more TWR -> need more engines -> increase weight

I can do extreme weight reduction if you are okay with poor appearance and losing some functionalities like docking or rcs

VTOL ?  Is it taking off or landing vertically, on Kerbin or somewhere else?

What about extreme STOL,  stalling speed under 25m/s, take off in it's own length kind of  stuff.   Quite a few of my spaceplanes manage that.

XSTOL and SSTO? Good job!

It's not that hard.   No conventional fuel tanks at all.  Need more fuel?  Fit more big S wings and strakes.

You'll want to climb up to 10km+ before going supersonic, so flight times are longer.  You might get slightly less fast on the speedrun, probably only 50 m/s or so due to diminishing returns, and have a slightly higher dry mass.  OTOH it will have good lift/drag ratio flying through the upper atmosphere on nukes alone,  you probably wont need any oxidizer.

If you take care of drag, a low TWR gives you a better mass ratio, as long as you make your speed run at sea level to go over 400m/ to open up the RAPIERs. Nothing simpler than an ascent that is basically a straight line, IMO. My benchmark for VTOL SSTO in 1.2 is this, even tough it has a tad high TWR:

 

Rune. So, you know, 1 RAPIER and ~9 Junos per mT of payload. More or less.
