I'm trying to learn how to modify, but I'm not there yet. I couldn't figure out how to modify the offset thrust, so I use the "old" LES. But I changed the SolidFuel value from 15 to 65 and it gave a perfect height of 2000 meters, which is realistic. I'm using FAR and RF. EDIT: Oh, while I'm at it, can someone point me in the right direction of adding a droguechute? If it is possible by just editing the configfiles?
