:wipes tear from eye: I want to say something like "That's so deeep" but the thing is I mean it...

lolol cute! Okay good to know. I'll be careful (and maybe end up tweaking some configs or something...). Thanks again.

Exactly the kind of information I was looking for, thank you very much!

Nice, very cute.

Cool, will do. I have now. Looks nice, thanks.

@sporkafife: That is a good point that people seem to miss a lot in these discussions. Re: No N-Body=No Lagrange Points: I still hold out hope that at some point Squad will a implement a special case of the sphere of influence concept with special effects that model Lagrange Points.

Hi all! I'm coming back to KSP after a break of a few months. I've just spent a bit messing about in vanilla and now I want to get geared up with mods before set out on my quest to map all the Easter eggs by exploration. (I'm kind of excited ) I just want to know if I'm missing anything really obvious, or if I'm going to run into compatibly problems, or if I have the wrong versions of things, etc. Here's the mods I'm planing on using: Deadly Reentry 2.1 ISA MapSat 3.3.1 Kethane 0.4.4 MechJeb 1.9.8 (or should I use 2.0.8?) Ferram Aerospace Research 0.9.41 Firespitter 5.1.1 Airships to Other Planets 2.0.2 RemoteTech 0.5.0.1 (with Probe Compatibility) B9 Aerospace Pack R3.1 For the record here is what I've downloaded: http://puu.sh/3aLTY.png

What? EDIT: never mind I had International System of Units and Specific Impulse confused...

First find the fuel consumption of the engine in kg/s (it is given in 'fuel units'/s). For example: A FL-T500 Fuel Tank is 2.5 kg full and .3 kg dry and holds 500 units of fuel... So 500 units of fuel have a mass of 2.2 kg -> 0.0044 kg each A LV-T30 LFE has a burn rate of '8' or 8 units/s or 0.0352 kg/s Then take the thrust (which is given in Newtons) of the engine divided by the fuel consumption. (Remember that Newtons are just m*kg/s2) Example: A LV-T30 LFE has a burn rate of 0.0352 kg/s and gives 200 N or 200 m*kg/s2 of force... so 200/0.0352 and (m*kg/s2)/(kg/s) -> 5681.8 m/s EDIT: okay so now you know how to do it without Isp too...
