Taming roll rates

[sneezy]

Guys

A newbie question. What setting in a PAR file is best changed to decrease a models roll rate. The models I like seem to roll at the very fast rate making hard to do some stunts. Typically Edge or CAP types.

Thank you

sneezy,

Roll rates are a function of several things. If it's just control sensitivity, make sure you've checked the exponential (Exp) box on the controller setup.

Then, to reduce roll rates, reduce the size of your aileron by reducing the span or chord or both. You can also shorten the throws by reducing the maximum angle of the control surface.

0.04 //chord length of the flap [m]
0.05 //start position of the flap [m] (span=end-start)
0.4 //end position of the flap [m]
-15 //Maximum Angle [deg]

One last thing to do too is to increase the "roll inertia moment Ixx" in the MAIN section of the .par file.

0.42 //Roll Inertia Moment Ixx [kg*m^2]
0.37 //Pitch Inertia Moment Iyy [kg*m^2]
0.76 //Yaw Inertia Moment Izz [kg*m^2]
-0.07 //Ixz [kg*m^2]
