Edit 2:
Update 1: CAS-1b2 Update 1
Mark 82s replaced with GBU-38s: CAS-1b3

Description and Miscellaneous:
It's basically an A-10.

I planned to build something with straight wings, upper-back engine, and an otherwise conventional configuration; all with some RCS reducing features in mind.
I used an A-10 schematic as size reference, but I pretty much ended up just copying its layout. (I had the rotary cannon as placeholder - roleplaying as an A-10, but I never removed it, so I just incorporated it instead)

As you know, the A-10 isn't exactly "light CAS", but the limit was a munitions payload of less than 4550 kg, and the present payload config weighs in at 4499 kg, so it's still valid.
The "Empty Weight" on the info tab in-game and on the website is representing empty-fuel, and not empty-munition; the empty-munition and full internal fuel (6000 L) aircraft weight is 9439 kg (hardpoints jettisoned).

No cockpit interior 'cause I didn't wanna. (Potato laptop)
No custom gear 'cause I didn't wanna.
No detailed custom munitions 'cause I didn't wanna.

Controls:
Toggle 1 - open canopy.
Toggle 2 - extend refueling probe.
Toggle 5 - jettison all payload (including hardpoints).
Trim - elevator trim.
VTOL - extend flaps/spoilers.
Otherwise standard pitch/roll/yaw controls.

Armaments:
1× 30 mm Rotary Cannon
2× GBU-31 JDAMs
6× Mark 82 Aerial Bombs
6× LAU-68/A Rocket Pods (42× Hydra 70s)
6× AGM-114C Hellfires
4× AIM-9L Sidewinders

Additional Notes:
50% throttle cruise at 600-900 km/h recommended.
Engines' 'bit overpowered. For more realistic performance just set the engines' powerMultiplier to 4.
TO/L speed ranges from 180-280 km/h (clean -> full).
Even though JDAMs are guided bombs, you still need to aim in the target's general direction.
"Weapon De-select", is there for when you don't want to lock a target (Only accessible through weapons menu).

Edit:
There are three errors.
- The pylon for the third port side Mark 82 Bomb is misplaced, probably cause some janky undo/redo, and I missed it.
- The activation group on the boom 50 part of the JDAMs are "False", which gets flagged by the debug log, as "False" is not recognised. Change "False" to "false" to avoid that issue.
- Alternating hard left and hard right rudder causing harmonic oscillation causes something to explode in the vertical stabilizer and horizontal stabilizer intersection. Fix by setting the internal wing parts' "disableAircraftCollision" to "true".
