Firespitter Mod is a special mod, you need install plugin before download and install this mod. This mod adds a great number of plane and helicopter parts to KSP. These include engines, wings and cockpits with interactive IVAs, as well as other useful things like landing gear, seaplane floats, trim tools and other widgets. Make sure you put the Firespitter files in the GameData folder the way it is presented in the zip file. This mod relies on many assets that have to be in the right folder, like sounds and textures. If you get creative with the file and folder names, stuff will break!
