I know nothing about multi engine planes. I have never seen the inside working of one either. One day I thought that I may want to tackle such a plane. But then I got to wondering how on earth the throttles are hooked up to a servo? After all, I would have to use trim on one engine at a time. How could that possibly done if they are all hooked up to the same servo? Is this a very technical thing or what. I am trying my best to use my imagination, but can't quite see it. Any explanations out there in this forum? Is this the type of thing that is explained in kits?
