This is a refueling truck painted by Air China. It does not exist in reality. It was designed by me. It has a robotic arm that refuels a fuel filler port mounted under the wing.My purpose is to hope it can fuel other players in multiplayer online mode.

(This is the multiplayer version)

Driver's Manual:
1.Pitch controls forward and backward, and Roll controls left and right turns.
2. When the driving speed is greater than 75km/h(46.6mph), sharp turns may cause rollover.

Refueling Operation Manual:
1. Park the vehicle in a suitable location to ensure that the robotic arm can touch the fuel filler.
2. Activate the brake.
3. Turn on Fire Alarm and Remove Static Electricity.
4. Turn on both power supplies.
5.Docking the fuel port.Throttle controls the extension and retraction of the robotic arm, VTOL controls the pitch of the robotic arm, and Yaw controls the rotation of the robotic arm. (When the VTOL output value is greater or less than zero, the manipulator will move continuously, if you need it to stop, please reset the VTOL to zero)
6.Open OilOutlet and Dewaterring and Strainer
7. Push up fuel pump 1 or 2 to start refueling.

Recover Process:
1. Turn on Homing until the robotic arm returns to its original position, then turn off Homing.
2. Homing the fuel pump.
3. Close all buttons that were just opened.
4. Check again whether the brakes, etc. are on (if the brake lights are on, check whether the Brake buttons on both sides are off.)
