hi guys

  i have currently playing around tiny 1.1 upto just before the test flight, and
have some problem with the servos and speed controller (they simply do get any

  I have test every link on the ground, wireless link is ok, gps is ok, even on
the GCS, when i change my throttle level on my r/c controller, it shows on the
GCS as well, but some how, the servos just don't react.

here is my airframe file on the setting 

<airframe name="FunJetmm Tiny 1.1">

<!-- commands section -->
    <servo name="THROTTLE"      no="0" min="1550" neutral="1550" max="1900"/>
    <servo name="AILEVON_LEFT"  no="2" min="1100" neutral="1504" max="1900"/>
    <servo name="AILEVON_RIGHT" no="1" min="1900" neutral="1495" max="1100"/>

    <axis name="THROTTLE" failsafe_value="0"/>
    <axis name="ROLL"     failsafe_value="0"/>
    <axis name="PITCH"    failsafe_value="0"/>

    <set command="THROTTLE" value="@THROTTLE"/>
    <set command="ROLL"     value="@ROLL"/>
    <set command="PITCH"    value="@PITCH"/>

  <section name="MIXER">
    <define name="AILEVON_AILERON_RATE" value="-0.45"/>
    <define name="AILEVON_ELEVATOR_RATE" value="0.8"/>

    <let var="aileron"  value="@ROLL  * AILEVON_AILERON_RATE"/>
    <let var="elevator" value="@PITCH * AILEVON_ELEVATOR_RATE"/>  
    <set servo="THROTTLE"      value="@THROTTLE"/>
    <set servo="AILEVON_LEFT"  value="$elevator + $aileron"/>
    <set servo="AILEVON_RIGHT" value="$elevator - $aileron"/>
include $(PAPARAZZI_SRC)/conf/autopilot/tiny.makefile


ap.CFLAGS +=  -DFBW -DAP -DCONFIG=\"tiny_1_1.h\" -DLED -DTIME_LED=1
ap.srcs = sys_time.c $(SRC_ARCH)/sys_time_hw.c $(SRC_ARCH)/armVIC.c main_fbw.c
main_ap.c main.c

ap.srcs += commands.c

ap.CFLAGS += -DACTUATORS=\"servos_4015_MAT_hw.h\" -DSERVOS_4015_MAT
ap.srcs += $(SRC_ARCH)/servos_4015_MAT_hw.c actuators.c

and following is my r/c file

<!DOCTYPE radio SYSTEM "radio.dtd">
<radio name="Futaba T6EXAP" data_min="900" data_max="2100" sync_min ="5000"
sync_max ="15000">
 <channel ctl="right_stick_horiz" function="ROLL"     max="1074" neutral="1520"
min="1942" average="0"/>
 <channel ctl="right_stick_vert" function="PITCH"    min="1109" neutral="1521"
max="1938" average="0"/>
 <channel ctl="left_stick_vert" function="THROTTLE" min="1107" neutral="1107"
max="1933" average="0"/>
 <channel ctl="left_stick_horiz" function="YAW"      min="1937" neutral="1524"
max="1103" average="0"/>
 <channel ctl="switch_L" function="GAIN1"     min="1100" neutral="1500"
max="3000" average="1"/>
 <channel ctl="switch_R" function="MODE"    min="1100" neutral="1500" max="1900"

  Does any one have any idea?
