The SADUA is a mach 3.7 (4600kmh) unmanned experimental aircraft that is supposed to be testing anti drag experiments. This plane has extremely high acceleration and also can slow down very fast using the 8 airbrakes equiped on the aircraft.This aircraft is very slim and aerodynamic, which means its fast but with one downside, if you go at high speeds over Mach 2.1 (2600 kmh) under 7000m you start to wobble a lot and crash if you dont slow down quickly. So make sure you go to higher altitudes to go at higher speeds.Also when you are landing, you probably wont need to use the parachute to slow you down because the airbrakes are very affective. You just might have to use it when you have barely any runaway left and/or you are going too fast (Mach 2). I reposted this because I had to fix some of the wings because it was out of place so when you would pull up or down, the plane would roll.

Also this plane is highly maneuverable (not at extremely high speeds or low speeds mostly maneuverable at 2000kmh)
