Conceptual 3D model of the Aircraft. The idea of aircraft control was that the engines are mounted on a pivoting mechanism, due to which the aircraft was controlled not flap, but through the change in engine position.
This is one of my very old personal work on 3D modeling. I've been wanting to put in order the model and publish this work. And finally, I did it, and the model is available for purchase.
In 3ds Max format with Aircraft model saved flame effects.
Initially, the 3D model was created on the scale of a children's toy and its size is approximately 20 cm. In the final version, I only corrected topology of mesh without changing the scale. But I think you can easily change the scale to your needs.
