Soyuz (In English meaning Union) is a family of expendable launch systems developed by OKB-1, and manufactured by Progress State Research and Production Rocket Space Center in Samara, Russia. The Soyuz launch vehicle is the most frequently used and reliable launch vehicle in the world.

Here are the controls:
Activate group 1 detaches launch pad.
Activate group 2 detaches the 1 stage engines.
Activate group 3 detaches the rocket base.

TIP: There are 2 launch types: first is quick launch and second is normal. For fast launch you need to remove the launch pad and just go up.

For takeoff you need to put the power up and detach group 1.

Hope you will enjoy! It was pretty hard to build this.
