Error on plane_aerobatics.lua

newaysfactory · December 31, 2025, 5:38pm

This time I loaded the raw, original plane_aerobatics.lua on the sd card and I activated the scripting in ardupilot.

When turning on the flight controller I get the error

Lua: /APM/scripts/plane_aerobatics.lua:287: No par

Looking into the script at that line, Ardupilot is failing to load the parameter “MAV_SYSID”.

According to documentation, it is actually missing among the available parameters in latest stable version of Plane: V4.6.3

What to do so?

Thanks

Found the solution!
I just retrieved the file from the 4.6.3 repository and it works!

Yes. If you download from the master branch, there’s a good chance it will be incompatible. 4.7 is staged to introduce a fair amount of change.
