+Heberth 159 Posted July 19, 2011 @Fubar512 that cobra was amazing! i can't wait for kick some a$$ with this Sukhoi. Just a suggestion to improve the pugachev cobra: back up the Data.ini... put it in [FlightControl]: StabilityAugmentation = 0.05 (this will prevent the plane go into a spin) and in the wings: AlphaDepart = 118.00 (or any number greater than 90) try with those values. if you do not like what you see, then you can return to the old FM Share this post Link to post Share on other sites
Fubar512 1,350 Posted July 24, 2011 in the wings: AlphaDepart = 118.00 (or any number greater than 90) Sorry, that's not a realistic value by any stretch of imagination, and realism's what I'm all about. Su-27s and 33s have an imposed 26 degree AoA alpha limit, that can be overidden during emergencies. The Cobra maneuver is a "controlled" departure (talk about an oxymoron!). What actually prevents the aircraft from departing into a spin, is aerodynamic drag from the horizontal stabs when they are returned to zero deflection during the maneuver forcing the nose back down. I've been able to emulate this drag, in a creative manner, without compromising the model's flight characteristics in an arcadish manner. The model performs the Cobra cleanly between 260-300 knots. Performing the maneuver at 300 KIAS, yields an 8.93 peak G-load, and scrubs off 155 knots of airspeed in less than 3 seconds, which still leaves you with just enough airspeed to maintain level flight at the end of the maneuver (that is, as long as one doesn't cut the throttle prior to the maneuver).

+Heberth 159 Posted July 24, 2011 ok, this was an sugestion to the plane don't yaw in the cobra. Share this post Link to post Share on other sites
Fubar512 1,350 Posted July 25, 2011 That's OK, I fully realize that it was meant as a helpful suggestion. Share this post Link to post Share on other sites
