Adjusting Aero Ace Bi Plane Par file

Hi brodie,

you can change the location of the center of gravity (CG) directly within the .par-file, which determines flight characteristics. The .par-file begins with the "main" section:

AIRPLANE

MAIN

9 //Mass [Kg]
1.993 //Roll Inertia Moment Ixx [kg*m^2]
2.53 //Pitch Inertia Moment Iyy [kg*m^2]
4.641 //Yaw Inertia Moment Izz [kg*m^2]
-0.04015 //Ixz [kg*m^2]
-0.08 0 0 //location CG X,Y,Z [m] <--- this line!
0.505 //Height of Center of gravity [m]

The first number is the axis nose/tail, with positive numbers meaning forward. In this case the cg is moved 8 cm to the rear.

Second entry is left/right with positive=right, third entry is up/down with positive=down. This coordinate system is completely non-standard, that's why I dismissed the usual terms of "x,y,z".

In the software "parEdit" you'll find CG under the main tab, works identically here.

Good luck,
Frank

See, you set up a virtual model that is absolutely correct to the prototype and, jeez, everyones a critic.

Well brodie it's just a matter of changing the C/G position like Treehugger suggested. ( Thanks Frank... )

If it's any consolation, my AeroAce flew like this 'til I moved the battery forward, so just think of this as a virtual example of the Hint's and kinks of AeroAces.
