The model was built near to scale in real units and based on real dimensional information, drawings, photos, and other documents. It was recently upgraded and updated with better textures, better geometry for much of the model and better renderings. This model includes animated propellers, animateable ailerons, flaps, elevators, landing gear, landing gear doors. It comes in several variants including the US Army basic version, USAF version, US Marines, NASA and two other air force versions. The models come in 8 formats, all the ported formats are prepared well to work correctly with every standard modeling software. The model is fully textured with all materials UVW mapped and applied. Most materials are planar mapped and major materials include texturing. All textures and materials are included as shown. 3ds Max model parts are grouped for easy selection, and objects are logically named for ease of scene management. No cleaning up necessary, just drop your models into the scene and start rendering. No special plugins are needed to open scene. In most cases the liveries are based on actual service liveries or paint schemes. Many of the countries who flew the plane are represented here. These models render very well and look very realistic using good animation and rendering technique. It can be used in an animated or static position within an animated video or possibly for programming for a flight simulation application. This model was not designed for 3d printing, these are digital files only. The North American Rockwell OV-10 Bronco was an American military light armed observation and COIN fighter, designed in the 1960s. It had twin Garrett T76-G-410/412 Turbo Prop turning a thee blade variable pitch propeller. They were crewed by a pilot and weapons controller/ observer. It was operated by the United States, Malaysia, United Kingdom, Thailand, Indonesia, Germany France, Philippines, and Belgium.
