3D Printable V6 Veicle 3D model

This is a V6 air engine powered tracked veicle, if you want you can try to pirint it in 3D, you can radio control it with 2 servos and 4 AA battery, the engine printed in 3D has to be a little bit modified but it should work, my racomandation is to put a brushless motor inside the crank case instead pistons and crank shaft.The model is quite big, i tried to print it but i finished the plastic before to finish the model XD
