This is an improved KF-2B fighter based on my KF-2A fighter. This is an air superiority fighter. It took me 2 weeks to manufacture it. The operation method is as follows: AG-1: Open the magazine, AG-2: Increase the VTOL rod to increase the force, lower the VTOL rod out of the air filler tube (only for decoration), AG-3: vertical takeoff and landing system, throttle lever to control engine power, pitch lever to control aircraft Forward and backward, roll rod controls the left and right tilt of the aircraft, yaw controls the head of the nose, AG4: parachute, AG-5: landing hook, AG-6: car engine (for aircraft ground scheduling) and machine Wing folding, AG-7: navigation light, AG-8: main engine. Trim Rod: Fine-tuning the aircraft to pitch. Matters needing attention: 1. This aircraft has a slight yaw, I can not solve this problem, please understand. 2. When launching a missile, try to aim the aircraft at the enemy plane, or point the belly to the enemy plane, otherwise the missile will easily hit yourself. 3. The engine will slightly tremble when the aircraft is running at low altitude. I can't solve this problem, please understand. Design and manufacture by S.P.F. Design Bureau. I hope you can enjoy it. Have a good time!^_^. Finally, I wish you a happy Spring Festival! ![https://ibb.co/BtzVqGD]
