I think at a certain point, they just stop helping. They also seem to work better the farther away they are from the axis.
Now, how the Hell do you guys manage to steer a rocket into an orbit trajectory? Because it's all my brain can manage just to keep the thing stable and headed towards a specific point on the compass, let alone with any real idea whether that's a good heading and keeping an eye on my speed.
straight up to about 40,000 meters. If you're above about 600 m/s, go ahead and angle down about 45 degrees in the direction you want to orbit. If less, keep it about 60 degrees up, if more, maybe about 30. As you do this your vertical speed should start to fall, if it doesn't angle down more. Try to get your direction pointer to point towards the horizon as you accelerate into an orbit. Once you hit about 2200 m/s, as long as you make it above 100 km, you'll be fine. Try to save some fuel for your Apoapsis, (point at which your vertical speed reaches zero.) Once you make it there, give yourself another burst of thrust in the direction you're travelling, this will raise the other side of your orbit above the atmosphere. It doesn't take much, just a few seconds of low thrust. maybe 10s at 1/3 throttle should be plenty.
If you make it that far without running out of fuel or spinning out of control or exploding, congratulations, you're in an orbit. Not a very pretty one, but it's better than a fiery death any day. Now just hope you kept enough fuel to deorbit. (again, doesn't take much.)
Edit: Also, don't keep it full thrust at the early portions of the launch. Low in the atmosphere, you'll hit a wall that atmospheric drag won't let you accelerate above. Get to this point, and then lower your throttle to keep yourself a bit below it, otherwise you waste fuel. (This is why I feel Solid rockets are a bit of a waste early on and too heavy to just lug along for later use.) You'll also get lighter, and higher and start to accelerate more as you rise. Keep lowering your throttle. You shouldn't be above 150 m/s below 10,000. shouldn't be above 200 m/s below 30,000. Once you get above that though, feel free to open up the throttle, just keep an eye on the fuel and heat levels.
