its made out of cheap materials like the German Jumo 004-b jet engines where so they had the life time of 30h and hadt to be replaced. This engine does the same. you should add insulator or cooling inside the engine which should help.
also improvements allways allowed dammit
But don't get me wrong, it has good quality!
Not a very good engine, can I improve it?
I've made one of my own, should I upload it?
