This huge ship circumnavigated Kerbin in 22 hours without refueling!
Reliable, fast, efficient!
I’ll write a topic about this journey later.
The engine is incredibly strong and reliable, just don’t overrev it (don’t run it over 42 rad/s).
Instructions for use:
1. Right click on a propeller blade and pin it to the screen.
2. Stage.
3. Change focus to the engine and back. You’ll now be able to change the propeller pitch while driving/sailing.
Performance:
Top speed on land: 144 m/s.
Top speed in the water: 81 m/s (tanks almost empty).
Max inclination while climbing mountains: 60 degrees.
Economy cruise: throttle at 33%.
Built in the SPH in KSP version 1.3.1.
