No throttle in any guided mode

Hi everyone.
I have used APM:Coptor a bunch, but I’m new to APM:Plane.
I have an “Ansley Peace Drone” set up and ready for the first flight.


Bench testing, I have discovered that in all manual modes ( manual, FBWA,) the throttle responds to the radio commands as described. But when switched to any auto mode, (FBWB, Auto, Guided, RTL,) the throttle shuts down.
I understand that the throttle should be under APM control in these modes and stick input is used to “bump” speed.

Question; Did I miss something in the setup/configuration?
Shouldn’t it be trying to accelerate to flight speed?
Or is this normal and I just don’t understand operation yet?

Hardware is full Pixhawk with an airspeed sensor. plane:3.3 loaded

Thanks for any input you might have.

Please provide tlogs and/or dataflash logs to help troubleshoot your issue.

Thanks for taking a look at this log. “74.bin”

Note that this is sitting on the bench with no prop.
