Choose activate1 to open the side missile box. Choose activate2 to open the main missile box. Then you can fight with the targets. This plane can vertical take off! When you on the ground, choose activate6 and turn the VTOL place(the left) to the front, this can open the VTOL engine and let tail nozzle turn down, then pull throttle at least 15 percent, the plane will leave the ground. When it rise to a suitable hight, choose activate7, the augmentation engine will work to push the plane.After that, turn back the tail nozzle, turn off activate6, congratulat you, you have finished a vertical taking off! Relative to J20CPromax2,this J20CPromax4 can vertical rise with max throttle benefit from it have better gyroscope settings,so you can attack enemy stability. Also,it optimized cannon,solved the problem about self-destruction during large-angle maneuvers.

操作指南：
选中激活组1自动打开侧弹仓，关闭1侧弹仓关闭，选中激活组2打开主弹仓，关闭2主弹仓关闭。
此飞机具备垂直起降功能！就像流浪地球2里的歼20C一样！具体操作是：
选中激活组6，将左边的VTOL档位调至最高，尾喷口将向下，然后油门推至15％及以上就可以垂直起飞了，垂直降落也是如此（如果关闭激活组8会无法调节尾喷口朝向）。垂直起飞到合适高度，可选中激活组7打开推力发动机，飞机将向前飞行，然后调节左边的档位将尾喷口调回原来的方向，并关闭激活组6和激活组7，加大油门，飞机就完成了垂直起飞进入正常飞行了！
此飞机尾喷口可以矢量控制，具备矢量机动能力。
打开激活组7，既打开加力发动机，可以飞的更快，加力发动机和矢量喷口同时受油门控制。
相比于J20CPromax2，这个Promax4版本有以下优化：
1.优化了垂直起降，得益于更好的陀螺仪设置，它可以用最大油门垂直起飞！以及在悬停时能更稳定的攻击地面的敌人。
2.更安全的机炮。调整了机炮位置以及碰撞箱设置，解决了Promax2中在大角度机动时开火可能导致自毁的问题。
