No. I tried the stock plane D45, take off, then keep it flying at about 200m, maximum throttle. After reaching 800m/s at about sea level(already insane), the accelrating is almost unstoppable, when 896m/s hitted, boom. Then I tired to fly higher. 4000m, 896, boom; 19000m, 900+,boom. How could this be possilbe!!!!
