Helicopter. There is script to transform tris to quad to only for this model ,but also for any model as agift. There is script to retopology model(instant meshes bridge+ instant meshes),run the script A bridge from 3ds max to instant meshes. Without leaving max interface, it exports, remeshes and imports the remeshed object back based on the parameters in the dialog. Installation: It can be run from any location (Maxscript -> Run Script...). If you want to put it in toolbar, menu or quadmenu, you can create a macroscript for it using Macroscript Creator. At first run, the script will ask for a location of your instant meshes executable - this will only happen once, provided that you don't reinstall max/remove the executable from the path. You can open model in 3ds max 2010.
