My first attempt at anything other than a plane, the "Eager Beaver" is an amphibious vehicle. When on land, throttle up & slide VTOL to control forward/reverse, use yaw to steer. Take it easy on the steering above 60mph, she can get a little tippy. When you drive into water, activate group one to optimize thrust & control the rudder in water; group two will lower the rudder when VTOL is in the forward position. When leaving the water, make sure you slide VTOL back to centre to raise the rudder, and before deactivating group one again. Its a little tricky to nail down getting back onto land, but its a good time once you do. Have fun!
