The rocket is twisting because the amount of thrust and mass are high compared with the rigidity of the design. You can improve the rigidity by using struts to hold the tops of your radial SRBs straight and parallel to the inside stack.

The major issue is that with every rocket design, when it comes to gravity turn, the rocket goes into an uncontrollable spin in that direction- the command pod torque seems to do nothing now. I tried adding several reaction wheels (like, 10 at the top of the rocket), but it had no measurable effect.
If the rocket is not aligned in the direction of travel, drag on each component will induce a torque.
But when the craft is spinning, there's no wobbling at all and pushing the keys has absolutely no effect. What's the cause of this huge change in stability mechanics and how can I adapt my older rocket designs?
Therefore, my preferred solution to stabilize the craft are tail fins, as shown on this suborbital tourist rocket: (The fins in the middle are for stabilizing the rocket after separation of the first stage) Reaction wheels are far weaker than atmospheric drag (they are designed for navigation in space, after all).

Launch. Yaw east 10 degrees at 100 m/s (notice I have to fight the aerodynamic forces - I only press the D key and the rocket attempts to go back to prograde) When the prograde marker and the rocket line up, I disable SAS - the fins will keep it pointing the right way. Decrease throttle around 300 m/s.

Why do rockets curve when they fly into space instead of going straight up? A: If a rocket just flew straight up, then it would fall right back down to Earth when it ran out of fuel! Rockets have to tilt to the side as they travel into the sky in order to reach orbit, or a circular path of motion around the Earth.
The stability of a rocket is its ability to keep flying through the air pointing in the right direction without wobbling or tumbling. Fins are used on smaller rockets to provide this stability and control direction. It works in the same way as placing feathers at the tail of an arrow.
Nowadays, rockets use a Gimbaled Thrust System. The rocket nozzles are gimbaled (An appliance that allows an object such as a ship's compass, to remain horizontal even as its support tips) so they can vector the thrust to direct the rocket.
If you press the spacebar and the chute icons light up but they don't deploy, it's typically because the pressure is too low. You can hit the stage button in space and they'll deploy on their own as soon as it's "safe".

Here are just a few of the reasons why space is so hard: Propellant volatility. Rocket launches are controlled explosions in the most literal sense. The combustive power of liquid oxygen and hydrogen, alcohols, and kerosenes leaves little room for error.

Orbital spaceflight from Earth has only been achieved by launch vehicles that use rocket engines for propulsion. To reach orbit, the rocket must impart to the payload a delta-v of about 9.3–10 km/s.
If the rocket is not aligned in the direction of travel, drag on each component will induce a torque. On components ahead of the center of mass, this torque will induce a rotation away from the direction of travel, destabilizing the craft, while on components behind the center of mass, drag will induce a rotation towards the direction of travel, ...
Therefore, if atmospheric drag makes your rocket unstable, reaction wheels won't help.
The first stage of your spacecraft will be expendable (not reusable) because it will be separated too low in the atmosphere. I recommend using an RT-10 Solid Fuel Booster as the first stage because it is very cheap.
The return stage will bring your kerbonaut home. I recommend using a Command Pod Mk1 with some Z-100 Rechargeable Battery Packs. Don't forget to add your Mk16 Parachute, heat shield and a Communotron 16!
When fuel runs out in the second stage and you are out of Kerbin's atmosphere, separate the orbital stage. If you've followed the above recommendation, this stage's activation should have armed all our parachutes for deployment, so the booster descend safely back to Kerbin.
The orbital stage will be used for orbit insertion and general maneuvering. Also this stage will contain most of your science modules. Add an FL-T400 Fuel Tank and an LV-909 Liquid Fuel Engine. Plan on attaching some SC-9001 Science Jr modules and Mystery Goo Containment Units for lots of science!
The Space Shuttle and Falcon 9 v1.1 are examples of reusable or partially reusable rockets in the real world. This tutorial will explain how to recover a spent stage so you can get those extra funds!
Hey there, i encountered this strange bug, so when I ascent, and then open map mode to circularize, then close map mode, all controls of all parts are basically dead, cant even stage. What to do in that aituation?
Why is this happening when I try to take off? How do I stop it from happening?
I've seen a number of posts by folks having issues with MechJeb. I've gotten to a point where I'd like to think I'm pretty decent at getting MJ to do what I want it to, so I thought I'd share a few pointers, as most of the "guides" I've seen to MJ are little more than buttonology.
