   This the second time I had build and VTOL jet R/C airplane was the last powered by ducted fan electric brushless DC engine  .The origine airfoil of the Sea Harrier  is 3310 , the dehydral angle are - 8 degrees .I decide the NACA of this airplane was as same 3310 .   . More light , strong material had been  used to contruct  this model airplane ;but the balsa wood is usually the good materiel to made it. The contructions of this aiplane all are  balsa wooden air-frame renforced by 5mm Depron hard foam ;  covered by thin alumium solar film . The gears system ( see on the  pic ) are quadricyclic , fixed , dirigeable and sprintable ( sea pic )  

 Wing : This is a 1005 square inch aircraft wing made entirely of balsawood. The wing uses the NACA 3310 airfoil with a shape and sweep angle similar to the AV 8B, but with slight modifications to the wingspan, sweep angle, and surface area (see figure). The two aileron system (see figure) is independent, with each aileron controlled by a 2.5 kg/cm² servo, hidden inside the wing. The hinges of the aileron and flap consist of four plastic pieces and are installed at the middle of the rear wing bar. Multiple holes in the wing's lamina have reduced the overall weight of the wing. The flaps are independent and controlled by two 2.5 kg servos, capable of reaching a 45-degree downward position. The entire wing is covered with aluminum-colored solar film

Gear system : This is a sprintable and retractable  quadricycle gear : all contruction are steel rod and aluminium tube ( see pic ) and this is the lightest sprintable gear i had made ( see pic )  . The nose gear was dirigable by an mini 1,5kg servos

R/C system , servo & other  link installation : Six 2,5kg mini servo for elevator , rudder , aileron and flap & one mini servo for nose gear , two for stabilizer gear under the wing and one 10,5 kg servos for dirigeable exhaust pipe systeme   . . The two receiver and the ESC are intall  fixed in high  of the fuselage and adjust for the CG ( Center of gravity ) at 35%-40% from the front of the wing cross section . The two receivers was place on the highest of the fuselage in the pilot copit and in the fuselage   

Gyro and hover stabilizer systeme : I use a strong 12V DC air-cooled mini fan to direct compressed air to the right , left wingtip, and the rear tube to control the roll, yaw, and pitch when the aircraft is hovering. An electronic gyro system is installed to ensure stability when the aircraft hovers in the air ( sea pic )
