This A-10 was originally made by BrunoBG and is already excellent. However I added a couple of improvements which I think make it even better.

Controls are in the craft instructions.

Onto the interesting stuff:

I added an ejector seat. I have several reasons for doing this, however the most important one is ejector seats are cool. Also, the actual A-10 has one, and it goes near bullets and missiles and stuff very often.
One word of warning, the canopy is quite stubborn and uses an XML modded detacher which is about twice as powerful than the normal one. Therefore, if you eject during a high-G manoeuvre there is a slight possibility of the aircraft spontaneously exploding. For everyone's safety, maybe leave the controls alone during the eject sequence.

Because BrunoBG had already used all the activation groups, I moved the airbrakes to the brake input rather than AG1, to make room for the ejection sequence.

The aircraft includes:
GAU-8 Avenger cannon with 1330 rounds of ammunition
x2 air-to-air missiles AIM-9J
x5 aerial bombs 500 lb. Mk.82
x2 (Air-to-ground missile) AGM-65 Maverick
x2 laser-guided bomb GBU-12 500-pound (227 kg)
Laser spot tracker Pave Penny
Flares and dipole reflectors
Emergency ejection seat
