Wing assisted rocket launch and aero-breaking

[KerbMav]

While trying to built an interplanetary craft and experimenting with launchers for the different parts I came up with two questions.

The main module of the craft and the two experimental launch stages attached to it was somewhat unstable when only considering CoM and CoT but the wings (mostly for looks) seemed to keep the flight path stable.

So, in regards to space planes and early orbital turns, would wings actually help to get heavy payloads into orbit - as an alternative to asparagussy rockets? Turning early and leaving the atmosphere tilted 70° or so?

And would there be any benefit from wings during aero-breaking aside from more drag? More control to keep orientation and better escape possibilities during ascent after the breaking?

Speaking of aero-breaking, I cant figure out to use this site correctly.

What would I enter for altitude and orbital velocity? These two numbers change a lot while closing in on the planet ...

Wings act as stabilizers and will help. never tried winged rockets but you might want to try an jet powered fist stage probably with some rockets to help you get speed and attitude, then you fly the thing as an plane until you reach 20 km.

This might be an good idea for an SSTO should potensialy be able to lift more stuff than most planes as you are more free in designing,

As for the site, you give your altitude at any point of your orbit, and your velcity at that time, and your periapsis so that it knows what orbit you are in. Then you give the desire apoapsis you are trying to get to, and it gives you the peripsis you want, and how much Delta V it will take to bring your periapsis down to that.
