I cant find THROTTLE_P ?????

Hi,

 

I need to slow my plane down in AUTO, apparently this is the PID value THROTTLE_P, but I can't find this anywhere.

 

Has it been renamed?

 

I can find THROTTLE_ALT_P and THROTTLE_TE_P but I'm not sure.

 

Any guidance appreciated. Incidently, throttle in RTL seems a lot gentler and I thought the one value covers both?

 

Cheers

 

Dave

    The parameters currently in use are THROTTLE_TE_P or THROTTLE_ALT_P.  Use the first if you have an airspeed sensor and the second if you do not.
  • Martin,

    Appreciate your help but Im on AP and not APM (should have mentioned that in the first place!)

    I have those settings configured in my AP config but think they affect fly by wire modes only.

    Looking in the flight tuning guide here: http://code.google.com/p/ardupilot/wiki/FlightTips

    They reference the PIDs for altitude hold but I cant see the same ones.

    I have a feeling theyve been renamed but not sure which is the correct one.

    Thanks again,

    Dave

    Hi Dave, I think all the information you need is here there is a section on the throttle use about 3/4 the way down the page.

     

    In the Config.h file I have added this code, I have it set to the following:

     

    #define THROTTLE_MIN         0 
    #define THROTTLE_CRUISE   50 
    #define THROTTLE_MAX        80 

    This seems to keep all in order on my ez*, have you tried this ?

     

    Regards
