How to make ArduCopter circle really fast?

Hi,

I have a particular setup. I need a quad copter to spin in a simulator in a circle with radius 1.5m at a speed 6.5m/s. Is this doable and if yes, any advice how to? Im trying to get this done through QGroundControl plan loiter turns step, but MAVlink could be enough also.

You can set circle_radius_m parameter to 1.5m and then the rate parameter can probably be calculated from your speed requirement

I am not sure if my Calculation is correct but the circle_rate parameter needs to be 248.7 deg/s for your required speed
