I always see super complex modded aircraft for download, but rarely something basic and simple. Building a stable jet can be a pain, so this is a great starting or reference point. It's a twin J50 engine jet, 13,000lbs, 23,000lb-f thrust, 750 gal of fuel (lasts about 20 minutes at 100%), very minimal design to build on, and most importantly it's STABLE without using complicated rcs or vtol thrusters or anything ridiculous like that. Just 2 static engines and control surfaces (front canards help stability greatly) and maneuverability increases/enhances with speed; best over 500 mph. Capable of reaching 70,000ft, service ceiling approx. 50,000ft (Yaw instability above that), combat ceiling 35,000ft.
