On Ground: Slide the VTOL control up and throttle to start. Steer using Roll control. Leaving VTOL at neutral (middle) will make the vehicle lighter and able to climb down cliffs with ease. Sliding VTOL down will cause the vehicle to decelerate. Activion of group 2 on ground will give the vehicle a small boost in speed. Activ as ting group 3 will give a huge boost to the speed (use with caution, and in small bursts). Using these two boosts the vehicle can climb up cliffs with littl le effort. The vehicle come with a working suspension made from moded detachers.

On Water: Due to the weird shape of the wheels you can steer on water just like when on the ground. Activating group 2 can help with steering on water.

On Air: To fly, slide VTOL all the way up and activste group 1 (or in reverse order). Once group 1 is activated, the vehicle will jump in air and unfold into a plane. If VTOL is slide down, activating group 1 will destroy the plane. Once the plane is stablized either group 2 or 3 must be activated to maintain flight (default engine isn't strong enough).
Enjoy!
