After completing Pluto, you should make this into an API for adding planets.

Use RescaleFactor, not scale.

So, you found a way to integrate it? How did you do it?

Use MechJeb's Landing Autopilot when you are approaching, it will give you your orbit after aerobraking.

Protractor, MechJeb, NovaPunch, Erkle's docking, EscapePod.

I leave a trail of dead bodies behind me, but I might attempt this time trial.

Well, the real N1 was notorious for breaking up about 60 seconds into the flight.

Could you put Earth in there, just for comparison? Maybe Luna as well?

Jeb is in a rover on Duna, waiting to be picked up and Bill and Bob are on Kerbin.

Can you make it account for the orbital eccentricity? My last Duna mission just missed because Duna was at apoapsis.

W,A,S,D + Shift?

Nope, it's basically a liquid engine with ridiculously high ISP. It doesn't refill fuel, it uses it very slowly, and there are no batteries, I just increased the weight to compensate, because it's a infinite resource anyway.

The ISP should increase as air gets thinner. However, it does the opposite with some engines here.

I use two NovaPunch NERVAs and a half-size 3 meter tank for my heavy transfer stage and they work great. The balance is nice. About the K2-X, I would like if it were to be upscaled, but then we would be missing an engine of that type. Also, I disagree with the ISP values on engines that perform better inside the atmosphere. I understand that it's for specializing them, but It's impossible in RL and I don't think you should use it here.
