R.200 Solid Only

Basically nothing remains of the OG craft. I was testing the craft this was based on, and was inspired by the solid upper stage. Ideally you don't want a solid 3rd stage... but I have never made a rocket that reaches orbit purely on solid motors, so I started editing, and here we are.

This is probably the nerdiest, best, worst, most deeply engineered rocket I've made.

Stage burn times. Nozzle sizes. Grain types. Everything has been finely tuned to get it just right.You use mods to make SRBs turn? pfft. Who needs mods. ;p

Basic grain on the 2nd stage is not a mistake. The spool time and way it ramps down is just what I want to fly this vizzy. (Basic grain is a ramp down grain.)

Treat this as proof of concept. It carries a 10t payload and a pixie kick stage, but it's been calibrated with that. Any solid-only rocket is going to be extremely sensitive to payload, so swapping it out for something else will result in a different flight path. The point is to show that if you have a specific payload in mind (maybe you launch the same thing often?), you can absolutely build a SRB only launch vehicle for it.
