The parts are extremely overpowered, and as a result, seriously fun!
Seriously though, I put a few xenon tanks on, and I got like 2.5 million m/s of deltaV. So, I made a dropship with the parts, and managed to land on Tylo.
Awesome mod! I haven't encountered any problems when using it so far.
Although, one thing I've noticed is that the solar panels are power generators rather than actual solar panels. I'm not sure if this is intentional or not, just wanted to mention it.
