J-36

The testing fighter from CAC, based on recently released photos and videos.
Note that in the photos, outside control surfaces serve as "drag rudder", like those on B-2. However, the inputs of the surfaces cannot be assigned directly to variables in Vizzy. I don't want to use slider, so the surfaces are assigned to ordinary aileron.
Another difference is the wing tip. From photos we know the tips rotate vertical to the fuselage. Previously I rotated them parallel to the fuselage, aka. mainly serves as vertical stablizer and provides yaw stability. The new photos indicates the wing tip rotates parallelly to the fuselage, aka. mainly provides roll or pitch control. I find it is more efficient rolling, so I assigned it to roll control. I tried to merge roll and pitch control but failed.
Then comes the question: how the craft maintain yaw stability? In reality, it is achieved via complicate control algorithm. Currently I only applied basic PID algorithms and treat control surfaces as Mealy Machines, so I need to find other ways to control yaw.
I add rotater to simulate vector thrust. Due to the size of the nozzle, the angle is restrict to 5 degrees. That means it still needs more force to maintain yaw stability. Given that, this craft rotates wing tips both vertical and parallel to the fuselage, while in reality it seems to be only rotating vertical to fuselage.
Last but not the least, the craft still needs cheating gyro, othervise the maneuverability will be a disaster. Yet the current maneuverability is still not as good as shown in videos. Increasing control area improves little, and I haven't find out an elegant way to deploy slats.
This modification improves outlook, making it more similar to the real craft. The control algorithm still needs to be improved. Maybe I'll figure it out if I have time......
