Is there a mod that adds a bolt on control point?

I've noticed that if you attempt to make a tall rocket where the tip tends to flex, one of the things that guarantees mission failure is when you have the control pod at the top of the rocket, and the flexing of the rocket causes it to oscillate back and forth, and then SAS tries to correct for that...

Fun stuff, and you can fix it by installing a probe core or something lower down, nearer to the center of mass. However, the "inline probe cores" and so on tend to take up space and mass, and I haven't found a 2.5m wide one yet in career mode.

In real rockets, you'd install a circuit board with an IMU on it, and wire it to the rocket's control system. You wouldn't need to add some huge module.

Well, you could use a few girders to mound a probe at the midpoint parallel to the rocket, one of the cubic struts should do the trick nicely.

You could use a large docking port as a decoupler and control from there. Just be quick to switch when staging.

An alternative solution to the oscillation problem is to download the Joint Reinforcement mod. It makes joints much more rigid so your rocket wont wobble as much. Doesn't increase the breaking point though, so your rocket'll still snap in half if you do bad stuff to it.

there is an r2d2 radially attached pod.

I just use a cubic octagonal strut and an okto 2.

There is also clipping. But do not put a probe in between a fuel tank and an engine. Also... Don't you mean SAS units instead?
