Thoughts on sideway static thrusters?

I just realized putting a thruster upside-down still contributes to top flying speed...

So naturally, the next question is: How much is it worth in combat?

Static pros: fuel efficient, higher-thrust, slightly more cost effective

Static cons: exposed, need clearance, the more you stack them in one direction the more vulnerable they become

Gimbals pros and cons: The exact opposite of static thrusters, except that they're also a bit smoother

My personal verdict: Static thruster for combat maneuvering can help keep building and fuel cost down, but too much will instead rend the craft vulnerable to enemy fire; best used in light craft like Lightning.
