[quote=@Krayzikk] Pretty good sized. Big enough that smaller machines usually run on fusion instead. The capacitors are a bigger factor than the size of the reactor itself, but for all intents and purposes they can be counted as the same unit due to the most common layout. Considering the size of an average Orbital at ~20m, but the Fortuna at 16.8, gives about a 6m clearance for its height. Taking into account everything in its torso I'd guesstimate that an Oberth reactor isn't usually any smaller than 4m tall at the usual scale. Okay, just wanted to make sure you had forewarning. I'd have felt bad if you didn't. You're all set. [/quote] Hmm. Glad I asked, that means I need to specify either in my CS or IC a few things, since it must have slipped under the radar how small the S.A.T.A.N. is, heh. Which would be better to specify that in? Basically I just need to say that there's a full sized Oberth in the Metatron but the Satan uses a smaller one for itself.
