Sorry about the long name... this is a variation on mrwhiskers85's cargo plane.

It has a go-cart in the back.
Ummm... yeah its also a suprisingly good vtol.

To take off activate ag-3, and put vtol 75% up to close the cargo door.

After thos activate and deactivate ag2

Then deactivate 3 and activate 1 and full up vtol.

You can add power until it takes off and hold a little down elevator.

Than jam the vtol slide to neutral and add power. You should be flying now.

To drop the rover, either land and activate 2 and deactivate 1 to drive the rover around.

Or you can pitch up and add power and the rover will fall out (make sure you have the bay door open) and once it clears the rear booms activate ag-7 to open the chutes then when it touches down deactivate 7 and drive away.
