Initial Tri Setup - No Yaw servo response

Hi All,

I'm building an RCexplorer style Tri with a AMP2.5, Turnigy9x (in airplane mode) and all the other HK.com stuff I need. I'm running Arducopter V2.9.1b and everything seems to work great (Pitch,Roll, throttle), except the yaw servo. In failsafe there is no output to channel 7 no matter the Yaw input from the Tx or movement of the AMP.

I'm hoping there's some setup step I missed somewhere but I've been through most of the relevant wiki pages an nothing seems to pop out at me.

Hope some one can help me out!

Thanks

Geoff

TLDR: AMP2.5, V2.9.1b tri, Turnigy 9x, no output to channel 7 / yaw servo

  • Did you managed to fix the problem?

    I'm also experiencing a similar problem.

  • make sure you have your receiver connected correctly to the apm. Channels 1-4 are for roll pitch yaw and throttle. I use 5 to control the mode. 6 and 7 control camera point on my gimball

  • Hi,

    I don't know how much you have checked. Did you remember to power the servo?  I have a APM 2.0 in a tricopter config, I see the APM2.5 has the input/output side power jumper removed by default according to the manual  Without this power jumper a power source will be needed to run the servo on the output side.  Note the user group recommends powering servos from a different power source from the APM - some servos can use a lot of power.

    Once the servo is working check carefully for servo direction else you will have a very interesting first flight.

  • Bump, I'd really like to not wait another month for another motor and ESC to make this a quad.
  • Not helping... but have to laugh @ TLDR!
