Automatic aerobatics. error on original lua script

ArduPlane Plane 4.6
1

Hi,

I’m trying to play with the scripted aerobatics.
I’m using a Matek H473 and plane 4.6.3.

I loaded the plane_aerobatics.lua but when I turn on the flight controller I get the error

29/12/2025 10:32:25 : nexpected symbol near ‘<’
29/12/2025 10:32:25 : Lua: Error: /APM/scripts/plane_aerobatics.lua:7: u

What is happening? I didn’t modified the script at all.

Thanks for the help

You have likely downloaded the entire webpage rather than the script file itself.

This is one of the most embarrassing things that has ever happened to me when asking for help online. But you are right.

So sorry to waste your time with things like this
