YL-5 reusable rocket with auto-landing Vizzy program

The YL-5 is a reusable rocket. With Vizzy program written in command chip, the first stage is able to land on target land position automatically.
Before ignition and lift off, there are 8 parameters to be set, including the coordinate of landing position, the orbit Apoapsis, separation altitude and so on. After lift off, everything is under program control. The 1st stage will be separated at 10km AGL, you can choose to continue controlling the 2nd stage or switch to the 1st stage.
If this is the first time you launch this rocket, I strongly recommend you to launch at DSC Launch Pad or DSC Large Pad, and setting all parameters with the suggested values, and take a demonstration flight. The first stage will land on the Drone ship to the east of DSC.

ATTENTION:
1.Limited by the game engine, there can be only one craft running Vizzy program. Even if the two programs are run in separated crafts, only the craft you’re controlling can be controlled by Vizzy program. If you want to land the rocket, as soon as the separation of first stage, toggle the map, select the craft named “YL-5-10”, toggle the map info window, and click on the “Take control of this craft”, the 4th icon, the program will be activated and take control of it.
2.If you want to edit the auto-landing program of the first stage, select command chip and edit the program. As for rocket prime control program which control the lift off, injection and upper stage, just edit the program in space capsule.
