     * Vivify MK1 codename Vidya (http://www.openuas.org/)
     Lisa M v2.0 (http://paparazzi.enac.fr/wiki/index.php/)
     With modified power routing by setting Jumper J1
     + Aspirin v2.2 inclusive MS5611
     + XBee XSC 900Mhz or XBP868 depending on location flown
     + uBlox LEA5H and Sarantel helix GPS antenna
     + Spektrum RX DSMX clone - optional mission demanding a R16Scan40MHZ RX
     + Analog Airspeed sensor
     + MK2 Second LisaM as FTD, plus additional power measurement for this board

     NOTES:
     + Using Total Energy control as control loop
     + LisaM with servo pins to the back of plane !
     + Engine battery voltage level separate sensor
     + FTD voltage level separate sensor
     + Flat yawing possible via Elevon UP Flapperon DOWN Mixing

     + OBC2014: Make sure that in link.ml
     link.ml - Paparazzi/sw/ground_segment/tmtc
     let ping_msg_period = 750 (** ms  CHANGED FOR OUTBACK CHALLENGE *)

    Modules to activate:
     + Current sensor on battery wires going to motor
     + geo_mag module if fixed for fixedwing

This way it does not fly straight into the circumference but instead it starts to make a roll as the one needed to fly in circles.
There is a value in the airframe file COURSE_PRE_BANK_CORRECTION which can be used to increase o decrease the effect. If set to 1 then the normal prebank is done. If set to 0.5 then half of the additional roll is done. This causes the aircraft to not roll enough in order to fly the intended circle and it ends up flying in a larger circle.  A value > 1 makes it fly a smaller circle.
