  @Luca - no idea on car stuff, but IM sure you'll get help just digg in then ask.. A few years ago a fella named Howard used the legacy board for a GPS guides boat. I'd bet the are a lot of similar things. Do some poking, find him and see his posts.

  Harry, thanks thought about thAt, but it worked Richter using same settings for thermo sensor so I didn't look. I'll look again.

  Hi all!!!! Two years ago i purchased one of this "old" ardupilot with an em-406 module, and i never be able to really test for the little number of members that can/want to help a newbie like me.. Now the numbers seems incredibly increase!!! Can someone help me please? I'd like to first test on an rc car... Only gps, no compass!!! Thanks to all!!!

  Just a guess, but could the throttle off endpoint be below the lost signal threshold?

  i had mine do that too i think my switch was making the ap think it was going into rth or auto rather than stabilize i reloaded the ap code and it fixed it i dont remember if i made changes or not also tho

  Dang it! All works great except now it is in the plane with motor hooked up (was testing without motor), now motor fires up as soon as AP is switched to stabilize...
  
  Any ideas? Checked radio, it's good.

  Yep they are moving. I just didn't get a lock, but IM just assuming the the guy I bought it from had the imu set for unlock. Mine is set for em406, so I may try that to see if mine will work before I set it to new gps.

  Right on Brian! sounds like you were having the same problems i use to have before i got the settings correct i know that the binary switch setting for output was one of my problems and also the baud rates throughout the various location in the code

  when you swich to stabilize does the imu movements move the servos in responce to your movements? it took a few loads of different settings to get mine to do it

  Well I have made some good progress.  I've used a combination of the new board and shield and new IMU.  I can now engage the AP and remain able to nudge the controls so nothing is lost, I also have movement from the servos when the ap is engaged and the IMU is moved (YES!)  Earlier today, I tested using just the Thermo sensor and got a lock from the ublox and just  minutes a go I moved my mock-up and all lights went blue indicating a lock, but it was lost just as quickly as it arrived.  Hopefully I can get a better lock from work...

  Brian, I've never specifically told the software "no IR".  I believe choosing IMU as the GPS type tells the software what to use by :

   #if GPS_PROTOCOL == 3
    // We are using the IMU
    // ---------------------
    decode_gps();
    
   #elif GPS_PROTOCOL == 5
    // this is the sim
    // ---------------
    read_sim_sensors();
    
   #else
    //  We are using FMA sensors
    // ------------------------
    read_XY_sensors();
   
    // if we are using a Z sensor, read that in too
    // --------------------------------------------
    #if ENABLE_Z_SENSOR == 1
    read_z_sensor();
    #endif
   #endif

   First it looks for the IMU, nope, Sim, nope, must be thermopiles.
