By these means I figure we can vector all four motors, allowing for the most efficient modes of operation. A benefit of this for our immediate goals is that I can now build two separate boats with the motors left over from my dismantled personal air vehicle. One will have motors driving the craft forwards for testing on water, and the other the motors mounted horizontally for testing in the hover. Incidentally, should there not be enough thrust for the latter, we can borrow two motors from the former and fix them around the centre of gravity of the latter.
Cookin' on gas, or electric which is even cleaner...
