How RCS works for Atlas Copco's Pit Vipers: Tower lowering

[perforistaescondido]

How about a real life video of a PV 235 lowering mast and if information travels at the speed of light,, why is this drill so much slower than a DML ?? and such poor traming performance with a single joystick as apposed to 2 traming levers ,, independent control of tracks and their directions to positon when required to drill holes in confined situations, Drill deck is to low to ground for drilling deep holes, jack up higher and lower mast between holes LOL ,, not a lot of time feild testing
