This is my second car, and my first amphibious car. The design is fairly simple, and is based off an SUV or 4X4. To control the vehicle, on land activate group 1, thrust to go forwards, and yaw to turn. When transitioning from land to water (or vice versa), push the left lever control (VTOL) up going into water, and back to the middle when going out of water. When in the water, deactivate group 1, and activate group 2, which activates jet engines. The controls are the same as on land, but you may need to push the right lever (trim) up at high speeds to prevent the vehicle from flipping. The top speed on land is around 380mph, and is around 270mph on water.
