# How can I fly faster???

## Recommended Posts

My Mirage III should make a speed of Mach 2.2! But the Aircraft starts shaking with Mach 1.0 and that's it! How can I make my Aircraft faster and fix this with the shaking?Thank's for any Help!!!Isra

Isra,If you are interested in a quick fix for the shaking, open the aircraft CFG file with notepad and scroll down to the section:;Moments of Inertiaempty_weight_pitch_MOI = 50000 //<---- increase if requiredempty_weight_roll_MOI = 45000 //<---- increase if requiredempty_weight_yaw_MOI = 90000 //<---- increase if requiredempty_weight_coupled_MOI = 0If you can identify the axis that is shaking - pitch, roll, or yaw - then simply increase the related MOI until the problem is cured.You can usually tell which MOI needs to be increased by watching the primary flight instrument indications, or by looking at the aircraft in spot plane view while flying at the airspeed at which the instability occurs. Should you be unable to detect which axis is shaking, then simply increase all MOI's until the shaking stops. Note that the Yaw MOI should be about equal to pitch + roll values.Don't be afraid to increase the numbers you find under the Moments of Inertia heading by 5000 or 10000 at a time until the instability stops at all airspeeds up to Vmo/Mmo. Remember to check the true airspeed of your aircraft as a maximum speed of Mach 2.2 will be attained at high altitude not 5000 ft AGL.Then if you are interested in learning about Flight Simulator flight dynamics be sure to check out the links that Fabio posted, there's plenty of great infomation to be found at those sites about how to set up the flight model correctly and avoid this and other flight dynamics problems.You may also want to visit :http://perso.wanadoo.fr/hsors/FS_Soft/index.htmlfor even more flight dynamics info, utilities and resources.
