Red: Fuselage crane
Place the nose cone on the fuselage block, then make the dimensions of the long fuselage block 0 for the rise and run. You can edit this tiny fuselage later to suiit your needs of where you want the block to be nudged to. (I learnt this mrthod frim skua, before 0.25 existed,)
Green: fuselage bulge
A more in deoth tutorial for its applications coming soon, as for now, you can edit the height of the fuselage to envelope the rocket launcher, or any other item.
Blue: rotation
Very simple, just rotate the minigun so the rear is slightly further into the fuselage block. (90* CC)
Yellow: also verys simple, mirror either thr bumb or the fuselage into the other
Grey: riser
Simply play witht he rise of either fuselage, you can use run with this, so long as you out the fuselages side to side instead of atop one snother.
Pink: fuselage wing crane
Simply lower the rise of the long fuselage (note: the fuselage can be any width or height you want, i made it as large as it is so its visible)
Snake: not a tutorial
Just press one, switch to orbit view, and keep rolling from side to side to move. Throttle here is required, but the snake can leap from water, and cans swim!
