My first try at an addon. Almost ready to begin texturing and should be finished in a few days. Will include 3 different payloads (ISS Transport, ISS Manned and Commercial) *Update 13.09* Download a first test version here: http://www./?isskxa16oaiju6k Only one payload option (which is just a fuel tank atm), some parts don't look how they should yet, textures are not that nice for now and a capsule decoupler is missing. Also values for fuel, thrust etc. not yet determined. Build Instructions: Nose-> Capsule-> payload module-> stage 3 fuel-> stage 3 engine-> stage 3 decoupler-> main fuel -> attach booster decouplers with 4x symetry on the main fuel tank where there is a dark spot on the texture.-> attach the boosters to the booster decouplers struts on the lower end of the boosters are recommended
