Hello everyone, I just registered to post this here.(I have recently got back into KSP) I see all of you talking about the ISP of this engine. But the thrust seems to me to be the issue. And I wanted to check with you guys to ask if this is just a bug on my version (running 1.0.2 at the moment) or that's how it's supposed to be : LV-909 Max Engine Thrust (ASL): 3.64 Max Engine Thrust (Vac): 14.78 This seems ABSURD to me. Even the wiki page values are different: [TABLE=width: 200] [TR] [TD]Maximum thrust[/TD] [TD](1 atm)[/TD] [TD]14.78 kN[/TD] [/TR] [TR] [TD](vacuum)[/TD] [TD]60.00 kN[/TD] [/TR] [/TABLE] So can anyone tell me what the hell is going on?
