I don't have the older versions anymore, sorry.

Any chance you would mind making the older versions (specifically v2.2) available for download for people playing on 0.30.1?

Cool Ideas. I did play around with a larger 2x2 heat exchanger but didn't really find it had any better use than 4 adaptive ones
... although that was before I put the restrictions on proximity in ...

I have a suggestion to improve things a little, why not add an additional 2 heat exchangers that cost more in terms of materials but can absorb more heat (increased from 900MJ/s to 1,500MJ/s), 1 for each size. Would be nice. If not, you could at least increase the amount of heat that the larger one absorbs as 900 for a much larger area does not seem all that good even though the efficiency is increased.

What do you think is missing?
I just downloaded and checked the package seems all correct

its missing some of the items from the mod

These would be great to place around shields to stop them overheating vs heat weapons

Ty now i can rethink the design of all my ship. AGAIN XD

Nice!
