This is based on JF1 Improved uponChanged to a more advanced body dashboardAnd a brand new weapon system.This will greatly enhance the aircraft's ground and air capabilities.In addition, I have improved the jet engine of the aircraft with a more aesthetically pleasing exhaust. This engine can provide a high flight speed of 1.5 Mach.The weight of the aircraft is extremely large, and the load on the landing gear is high. It is recommended to experience it in physics or above to avoid any impact. And in order to prevent the landing gear from being pulled out in high overload situations, the aircraft is equipped with a landing gear locking structure. When using slowly, be careful to prevent explosions due to the landing gear locking structure.The number of parts for this machine is 1058.
