PDS v0.5

/*
* Original author: GreenPixel , ultra precice speed controll
* Edited or butchered by Suicide_Jack
* Setup:
* 1 place Programmable block name it "PDS Controller"
* 2 rename one or more thruster that thrusts forward "PDS Thruster"
* 3 setup timer block that triggers itself and this script
