I will upload the new version of STRIKE FREEDOM GUNDAM some other day, so it is definitely not a clickbait.

IMPORTANT

the auto floating cannon is actually an upgrade version of joshuaW"s one. And I've got joshuaW's permission .
It use new core(very important)
It uses CANNON instead of gun.
It use PID control all the time including while deactivating the auto floating cannon.(no magnet)
While deactivate1 actually it is like the auto floating cannon and the car is a whole one ,but they are SEPERATED
And I've got joshuaW's permission .
This work actually proves that auto floating cannon definitely can be developed in the game.
