With ddvc's permission, I modified his MiG-21F13 by removing the cannons on both sides and the air brakes, replacing them with an integrated wedge-shaped airbrake. I crafted a movable pitot tube, designed a new canopy, and added rear cockpit instruments. The parachute brake, originally located at the tailfin, was relocated to the base of the vertical stabilizer, for which I fabricated a side-opening parachute compartment cover. Additionally, I created a simplified combustion chamber interior and converted some of the flight control systems to a 'funkytree' format, which might result in very smooth operation🧐

In terms of controls, I haven't made significant changes; you should be able to adapt to its handling effortlessly due to your proficiency!

AG1: Jettison left missile (do not use on ground)
AG3: Jettison right missile (same as above)
AG2: Drop external fuel tank and deploy air brakes
AG4: Deploy parachute brake
AG5: Instructor's periscope
AG7: Eject seat
The cockpit canopy will automatically close after reaching a certain speed. The landing gear and periscope are interconnected.
Have fun!🥰🥰🥰
