This 3D model was originally created with Sketchup 13 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 what would've happened in real to the R-5A through C series. The plane would've broken in parts, how many systems you use, no result would make it. Too narrow, too long = fuselage in parts. Such engines would never be held by such thin engines. The landing gear doesn't maintain anything. The tail and rear wings are too far away which makes them fall unto the ground. Just showing, that calculations, blueprints, and weigh measuring {even simple} would make this, a successful flight. The planes differ like nothing that's why I made this crash named like that. EDIT: Damn guys sorry forgot credit! Thanx to Richard Drummond for the fire effect and 707 for the R-5C.
