(TEASER) Variable Stability Research Project (G100):

After several hours of designing and fine tuning, I have completed what is probably my most advanced scratch-built project to date: G100, or VSRA-1.

As the picture above presents, it's rather unique looking aircraft, featuring forward-swept wings, control canards, and 9 control surfaces (including the canards) that receive special computerized inputs to control the aircraft's stability.

In one of the pictures below, you can see that the CoM/CoL are nearly in the same position. This should have made the aircraft "unflyable", but for some reason it operates fine (probably related to the wing configuration). What this offers is enhanced maneuverability.

The stability of the aircraft is controlled by the Trim slider. Moving the slider up decreases stability, and moving it down increases stability. This affects the aircraft's ability to perform extreme maneuvers. This is done by regulating the amount of PitchRate input that goes into the controls. When PitchRate is positive, it increases pitch input, which increases the PitchRate, and the cycle continues rapidly until the aircraft destabilizes itself and performs an extreme pitch maneuver (if the destabilizer slider is high enough). The same applies to negative PitchRate.


I plan on making a second VSRA, that will most likely have a delta-wing, and a thrust-vectoring engine.

Thoughts or suggestions? Let me know!
