Is there a way to lock rocket movement midair?

[Ducks]

I usually build really big rockets and it's hard to keep them on track because they keep turning. I try using SAS but that's usually a hit or miss. Is there a way to completely lock the movement of the rocket? (A wat to make pitch, yaw, and roll not change) Thanks!

Some mods will let you tell your rocket to point at some specific direction.
Mech Jeb and remote tech should both have that feature.

Try making your rockets more aerodynamically stable and they shouldn't fight you too much.
If you absolutely have to put a giant high drag object into space, put it on the bottom of your rocket and put your engines on top and the drag will help stabilize your rocket.

huge rockets turn because connections flex. Mass is too high and engines too powerful.

Use better connections and larger parts. You can add struts in a way they are more rigid (frame style), you can turn on autostrut on every part or try rigid attachment (they may break apart instead of flexing though), you can redesign the whole ship so flex counters or balances out itself for most parts and stays straight. And finally you can stop building huge. Big is big enough for all tasks in KSP. Size doesn't matter in KSP, only proportions. Everything is scalable. 5ooot rocket is no better than 500t one.

Launched 11000 ton rocket yesterday, smooth and steady. Check your CoM and connections and enable aerodynamics overlay (F12 by default, if you see big scary red line somewhere - that's where to look).

Heavy booster tutorial helps take some of the wobble out of most designs (very old version of KSP)

Doesn't time warp reset all rotation to zero?

Physical timewarp does not.
You have to use physical timewarp in atmospheres.
