如果火箭发射后操作困难，请自行在卫星上安装一个陀螺仪，roll和pitch锁定在5°，设置在2号按钮(那是整个模型唯一空闲的按钮了)

Rocket fast lunch system,简称FRLS，一款装在重型卡车上的固体运载火箭。可以将一颗卫星发射到最高300km的高度和接近第一宇宙速度。（当然，如果你有需求，也可以把卫星换成核弹。）整个系统共8人，一名驾驶员，一名操作手，一名指挥官，三名工程师，两名工人。其中，第一摄像机在车体上，第二摄像机在操作手身上，第三摄像机在驾驶员身上，第四摄像机在指挥官身上。
至于操作，第一按钮负责火箭点火和低高度火箭控制发动机，第一按钮+Trim控制箱子盖的打开。
第二按钮负责火箭的第一和第二部分分离和第二部分发动机。
第四按钮负责高空火箭控制发动机和整流罩的分离。
第五按钮负责卫星发动机点火和卫星与火箭的分离。
第六按钮+VTOL控制支撑盘的升起。

第七按钮控制灯光。

第八按钮+WSAD驾驶车辆，第八按钮+VTOL控制箱子向上或向下，第八按钮+Trim控制支撑腿的展开。

稍后评论区将发布操作演示视频。

From machine translation
Rocket fast launch system, or FRLS for short, is a solid launch vehicle mounted on a heavy truck. A satellite can be launched to a height of up to 300 km and close to the first cosmic speed. (of course, if you need it, you can also replace the satellite with a nuclear bomb.) There are 8 people in the whole system, one driver, one operator, one commander, three engineers and two workers. Among them, the first camera is on the vehicle body, the second camera is on the operator, the third camera is on the driver, and the fourth camera is on the commander.

As for operation, the first button is responsible for rocket ignition and low altitude rocket control engine, and the first button + trim controls the opening of box cover.

The second button is responsible for the separation of the first and second parts of the rocket and the second part of the engine.

The fourth button is responsible for the separation of high altitude rocket control engine and fairing.

The fifth button is responsible for ignition of satellite engine and separation of satellite and rocket.

The sixth button + VTOL controls the lifting of the support plate.

The seventh button controls the light.

The eighth button + WSAD drives the vehicle, the eighth button + VTOL controls the box up or down, and the eighth button + trim controls the deployment of the support leg.

A demonstration video of the operation will be published in the comment area later.
