Ok guys, so after about a week of work, I present to you the LIEBHERR R974c excavator ( If you don't know, LIEBHERR is a German construction vehicle company).
Note that the tracks are fake : (

Here are the controls:
Group 1:
VTOL-left track
Trim-right track
I know the driving mechanism is a bit strange, but it's more accurate since pretty much all tracked vehicles have independent tracks. Also, this system allows it to turn on the spot. Don't worry, you'll get used to it : )
Forward- VTOL + Trim up
Reverse- VTOL + Trim down
Turn left- VTOL down + Trim up
Turn right- VTOL up + Trim down

Group 2:
VTOL- excavator base rotation

Group 3:
VTOL- boom elevation (joint 1)
Trim- boom elevation (joint 2)
Throttle- scoop scooping

Group 5 -lights

Note that I can't XML mod since I'm on IOS. therefore the boom sections can only be moved in one direction from there starting point. Sorry guys! Also, the bucket weirdly snaps up into the arm when you throttle up over 94%, so I would suggest not doing that.

Please excuse the super derpy-looking "LIEBHERR" writing (there's only one R because there wasn't enough space).

Oh and how could I forget- Big thanks to MechWARRIOR57 for the 25hp engines!!!
