This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This is a turbo engine I came up with. Jet engine, that I used, is by author I don't remember, so please look for the contributors box. Gear mine, design mine. Although I modified the engine so much I don't think it's not mine :P . It is working with landing gear, so it's pretty much for enourmous airliners. Sorry if I spelled it wrong :'] , the word enourmous, or how it's there..ok, nevermind. Back to topic. I called it magni since it transfers the pull of the double engine into the large generator, behind the gear box. The gear flaps are actually not required, since it will only eat space. The gear mechanism is pretty easy, since it only uses metal cylinders that pull the gear up on hinges, and then are attracted to their place with the strings. They are pretty cool ;T . He-he. This will also be used in my mega project!!! Strings by SketchyPhysics :P !
