For those who don’t know, KV-220 is a tier 5 heavy tank,previously exclusive to the Russian server. It’s main advantages are thick hullarmor and the fact that it has a limited MM (it will not see tier 7vehicles). Please note that the fact EU wikipedia doesn’t mention this fact...
特技飞机的另外一种策略是使用特殊的油箱,如位于机翼下方的 header tank。一些特技飞机,比如 Super Decathlon 型号的飞机的油箱在飞机上方,飞机正飞的时候,重力使燃油向下流入燃油泵。但是在机翼下方还有一个油箱 header tank,它也和燃油泵相连。在飞机倒转时,这个油箱就到了机翼上方,可以利用重力为引擎供油。
