It has 18 servos to make sure it takes off and lands safely. Its take-off weight is 149 KG (328.5 pounds), which is the weight of two grown men! The fuel tanks capacity of this airplane is 4 x 6 liters.
Built to a 1:6 scale, the model was designed and built by Steven and Matthew Bishop. According to its creator, it took more than 5,000 hours to build the plane, over eight months, using styrofoam and balsa wood.
