Hello, I am new to this forum, and in ardupilot.
I installed the ardupilot in my plane and configured everything, at least I think.
But when I put it in RTL mode, Circle … the engine does not run, on an electric motor.
The display shows armed motor, and then Fais safe
Please do not know what may be happening.
I would appreciate any help.Thanks

Welcome Dario: It´s important to get help that you share the log when your issue occurs
and, in the title try to resume your issue.

Dario,

Did you start by getting Manual and FBWA modes working first? The RTL and Circle modes require a working compass and GPS module so it is best to get the basics working first.

Hi, thanks for your reply.
I have the compass calibrated, the engine armed …
The engine trim to 60% …
When turning the mode is in manual mode and the motor works well. When put into automatic mode is when the motor does not work.

The LEDs are in solid red and fixed blue.
I have version apm 2.8.

…but flying or on the floor? probably don’t work on the floor
