Cougar - Dead bands and axis tuning
« on: May 31, 2002, 04:40:16 PM »
Enjoying my new cougar and getting used to the springs I think. But I am noticing trouble with nose bounce at slower speeds. Even a plane like the Pony D that has a very pointable and stable nose bobs arround when I need it stable. I think it must be due to the fine tuning of my Axis.
I am looking through the manual but maybe some old TM hand can save me some time and point me in the right direction as to how I should tune the thing... And should I do it in AH or the cougar control panel?
Thanks in advance...

I had the same prob..

I re-did my stick scaling in AH.
You can also assign a button to re-do the onboard
stick scaling.  I'm working on one to change the stick scaling when I flip the 3 way to what I have defined as "Landing" mode.
Right now I have mine set up for 3 modes of operation.....

Bomber
Landing/Take Off

You can set up the stick scaling in the Cougar Control Panel, or you can do it programmatically, using the CURVE statement.

For example, I tie the sensitivity of my joystick and rudders to the position of the dogfight switch, using a statement like this:

CURVE /u (JOYSTICK,-2) (RDDR,-2)
/m (JOYSTICK,-4) (RDDR,-4)
/d (JOYSTICK,-6) (RDDR,-6)

Note that CURVE (axis,x) with x=0 yields a "flat" response (i.e., equivalent to the AH axis filter with all sliders at the top) and that x<0 yields progressively less sensitive responses (i.e., equivalent to the AH axis filter with the sliders progressively set more towards the bottoms of their ranges).  Positive values of x actually yield responses that are more responsive than what can be achieved with AH's filter.  I don't use those, because I find them too twitchy with Cougar's high "break" tension.

Once I set up my responses in my Cougar AH profile, I set all of the axis filter sliders (in the AH joystick setup screen) to the top of their ranges so that I do not get a "double filtering" effect.  

With my set-up I have never noticed any nose bounce.  I think the reason that you see bounce without "toning down" Cougar's response is that it takes quite a bit of force to move the stick from its central position and after applying enough force to "break" the stick out of its equilibrium position, it is difficult to stop is just inside its active range.  Toning down the response compensates for that physical imprecision by making all deflections near the beginning of the active range look more similar to one another.  Another thing that helped me was to set the joystick deadband to ZERO in the Cougar Control Panel.  I know that seems counter-intuitive, but with the Cougar's high tension, I find that it helps.
