    Re: Phoenix code inverting servo directions

    OK..got it:

    define it as:

    #define cRRCoxaInv 0
    #define cRMCoxaInv 0
    #define cRFCoxaInv 0
    #define cRRFemurInv 0
    #define cRMFemurInv 0
    #define cRFFemurInv 0

    Hi Zenta,

    Thanks for your reply. After spending some serious effort reading the code, I came to the same conclusion as you----it is a real challenge to add terrain adaptation.

    I have decided to...

    Hi KurtEck,

    Thanks for your reply.

    I am using your T-HEx 4 dof code as you mentioned.

  20. Question(s) Re: Setting up Arduino Mega 2560 with RC input control with modified Phantom X

    Hi tician,

    I was going with $50 US per servo = $70.6 NZD
    70.6 * 24 = $1694.4 NZD
    $1694.4 x 1.15 (15% tax) + $64 (customs processing fee) = $2012.56 NZD

    That is excluding shipping and doing a...
