Bugs or my mistakes

[Fogliato]

Good morning, friends, I've started a career with an F86 A5 group, 334th Fis USAF. I'd like to point out that despite the controls being so easy to use, I can easily take off and land. I even bought a new joystick, a TRUSTMASTER 1600 M, but I can't shoot anything down unless I'm on autopilot. I'd like to point out some discrepancies I've found with the controls:
The airbrake button I assigned to the joystick only works when the plane is on the ground; it doesn't work in flight.
The E button on the keyboard, which is supposed to start and stop the engine, only turns it off and doesn't start it again.
If I equip the plane with supplementary tanks before takeoff, the right wing remains attached to the wing, while the left wing remains on the ground.
Am I doing something wrong or are they a bug?
Regards

Sounds strange. Can you take a screenshot?

Check your key/controller bindings. If in doubt just reset them to 'default'
