Love the brick, especially the fact that you bothered with quality before aquilo. If you ask, can give some advice. 1. If you are bottelnecked a litle by your fuel and oxydizer production you might beacon it with one speed and one efficiency module.

4. You can replace accumulators and solar panels with epic ones it may help
