Upgade:
1. Cut parts count from 375 back to 370.
2. Replace the Act6, which the Parachute change into the flight Corrector, it can make this aircraft never auto-roll when it above 40000+ft high.When your computer never auto-roll or yaw, please delete the v2.1’s Act6 and change back into v2.0's parts.
3. Weight loss from 104,000lbs into 97,000lbs, so can make it more swift.In two v2.1 teaching videos, it is showing most vividly.
4. Put the Radar inside the nose of aircraft,so can make its machineguns have more hit rate.
