Using Terrier Engines with RCS controls

[NewtSoup]

Hi Guys,  I am kind of back again at the moment.  Planning a new "lets play" in KSP to get my eye in again before KSP 2 comes out.

One thing I've always wanted to do is use LF engines ( not Vernor - they are weak ) as more powerful RCS thrusters.  Has anyone managed to do this with action groups?

I did once write my own mod which took the engine parameters of the Terrier and made it into an RCS thruster but I couldn't use the terrier model.  I had to use a scaled up Puff engine model for the mod to work, it did work very well and I had supreme control of one of the old orange fuel tanks ( it became my fuel barge from Minmus Surface to a station in LMO )

I'd like a more practical way of doing this.  In my head canon tying in full LfOx engines into the RCS system is a very Kerbal thing to do so I have no issues in trying to remake my mod if it's not possible any other way.  

If people remember the Eagle ships from Space 1999 - that's basically what I want to recreate in KSP with their 6 degrees of control ( or if you prefer (or haven't seen Space 1999), think of it as an LfOx drone )

I have found a mod by @Smeagol Bigger Vernor RCS.  It has the functionality I want.

You might check out the Throttle Control Avionics mod, a bit of a learning curve, but very fun to play with
