Tankopter? You really never heard of it? Well, if not, then it is better to see once than hear a hundred times. Well, just look at it is not enough, you have to hold it on the fly, so he did not fall down. To do this, press the mouse button, and it will fly up, but do not overdo it, crashing into the wall can not be horizontal, and vertical to fly around the side or in the presence of explosive it can be undermined.
