This is an upgraded version of the Airbus A340-600 that I made. This version features a minigun, six Boom 50 bombs and a large propeller mounted at the rear to enable reverse thrust. To activate the slider for the propeller, simply press 1. Use R to switch the targeting mode to 'Air-To-Ground' to enable the bombs (and I forgot to mention - the wing mounted rocket pods). To make a smooth landing, you should manipulate the propeller's thrust in a way that will increase the speed (you need 215mph to land smoothly, or else you're gonna fall like a rock and explode into a million pieces as a result of the bombs mounted underneath).

I also forgot to mention - the propeller is always powered on, so quickly press 1 to take control of its thrust and push the slider all the way up. If you wish to keep the plane stationary while on the ground, hold LCTRL.
And when you have touched down on landing - push the slider backwards to engage reverse thrust and slow the plane down. Holding LCTRL also engages the air brakes, which slow your plane even faster than reverse thrust alone.
