Will you make 0.90 physics to 1.0?

[SirDerpyHerp]

Hello, Squad Developer or anyone. When 1.0 came out, it has a new physics, but the new physics made me unable to go into orbit or higher than 10 km. The 0.90 physics is way more better in my opinion. Will you add an optional option to bring back 0.90 physics? It can make an update of a lifetime .

I really, really, really can't understand all the trouble people are having adjusting to vaguely realistic aerodynamics.

Why can't you "go into orbit or higher than 10km" ?

It really shouldn't take more than 10 minutes of playing around to get something that can do that, and then from there you can make more and more elaborate designs.

I got this into orbit in 1.02 with just 2 launches... of SSTOs...

Surely you can get a capsule above 10km...

My guess would be that the OP is still flying up to 10 km and then banking over 45 degrees and instantly flipping out.

OP you have to turn way more gradually, Scott Manley among others has put together a tutorial on launching rockets in the new aerodynamics

Have you tried looking at some tutorials? There's lots of good ones around. Here's a thread full of useful links: http://forum.kerbalspaceprogram.com/threads/28352

Launching a rocket successfully revolves around one simple rule right now: "Heavy bits in the front, draggy bits at the rear." The details of how you achieve this can vary, but ultimately it all boils down to trying to come as close to that as possible. Any rocket that follows this rule will automatically fly straight. Any rocket that grossly violates this rule will automatically try to flip over and fly in an orientation where the rule applies better, such as backwards. If that is the case, you will not go to space today.

The simplest way to make your rocket more conforming to this rule is to build it like an arrow. Make sure the tip is very pointy. A flat surface at the tip will ruin your day very quickly. Form a single, straight shaft without anything sticking out the side anywhere. Finally, attach guiding fins at the bottom of the rocket (ideally ones that can also be used for steering). Like, literally as low down as you can go. Mount four of them in symmetry. Here's an example rocket. Look how pointy and straight and arrow-like it is! Now all it needs is a set of fins at the bottom. It can fly without, if you're a good pilot, but to be safe, better put some on. Delta Deluxe winglets work well.

Once you have your rocket built according to the cardinal rule, you need to "un-learn" the old way of going straight up to 10km and then turning sharply to the side. Instead, go up to 1 km only, and then turn very slightly to the side. Just a single notch on the navball. And then... turn off SAS and take your hands off the controls. Stop steering and just watch your rocket go. You'll see that it turns sideways slowly by itself, in a very smooth, very stable fashion called a "gravity turn" (because gravity pulls the rocket to the side). Maybe it will turn too fast - then you need to go a little higher before you start your turn. Maybe it will fly too straight and not turn much at all - then you need to throttle down your engine a bit after you start your turn.

You'll probably feel nervous taking your hands off the controls even as your rocket is tipping to the side, but remember, you want it to go sideways to get into orbit. It just needs to tilt at the right rate, which you can control by the timing of your initial pitchover and your engine throttle.

I'd place bets that this will never happen

Squad are happy with their new aerodynamics, and the majority of players on this forum have adapted to it and discovered that it is absolutely viable and makes for a more interesting game than pre-1.0. Under the circumstances, I'd suggest finding some tutorials on how to build rockets for 1.0.x rather than looking to return to the placeholder physics of yesteryear.

If you must have the old aero model: Open the debug menu by pressing Alt-F12, then go to the Physics tab, and under Aerodynamics enable "Use Spherical Model". This will give aerodynamic behavior very similar to 0.90.
