Just wondering how update the spreadsheet is? I was looking at the work tracking and a little confused. What does N/A mean? Obviously, not applicable but I've been closely following RSS and that seems to be being worked on. I've not been told directly but I understand that it's now in the pre-release / bug fixing phase? Will the spreadsheet get updated to confirm this or will it just go from N/A to Complete? Also, how did you guys come up with the RL stats for parts? Obviously from RL sites but take engines for example. Is there a list of what RL engine the game engines are designed on? What if they're not actually designed from a RL engine? Do you just pick a part and say, "right, we'll turn this one into the RL XYZ-Maxi engine". I was taking a look at the stock parts which haven't been converted / patched / configged yet. The Big-S Delta Wing for example. I likened it to the Space Shuttle Orbiter Wing. While there's a lot of tech spec on the Space Shuttle Orbiter, Wikipedia, ESA, NASA, Braeunig, I couldn't for the life of me find much about the wing itself and as such, the mass I have no idea about. In this case, how would you go about it? An arbitrary educated guess? I know none of this is really helping, but I'm interested in the process used to do this stuff and possibly in the future I can help out. Also, linked to the "process", while there is information on the API syntax and editing config files etc - I believe what would be incredibly useful for us morons / non-ksp literate people, would be 2 or 3 image-plentiful / video guides of creating a patch config file. For example Today we're going to create the RO config patch file to convert Big-S Delta Wing to RO standards. PIC PIC PIC First we need to find out RL stats which we can by google, nasa, x, y, z. PIC Then we create the cfg file PIC We start of with @part[codeystuff] !needs[xyz]. This calls ABC file and checks we have DEF file. blah blah. PIC PIC You can see here that max temperature on the original is 4000c whereas in RL it has a max of 2178c PIC We alter this by adding @part[Deltawing] !maxtemp = 2178 PIC Etc etc. Of course, that would be a chunk out of someones time but I think it would really help those on the edge of understanding, thus save time in the future.
