ArduCopter 20" tuning issue

ArduCopter Copter 4.3
1

Hello everyone,

I’m currently designing an assembly based on an EFT chassis, four X8s with 20" propellers and an x7+pro controller.

I have several issues with its tuning flights that I can’t resolve.

-Lack of responsiveness on roll and pitch (in any flight mode)
-Total instability in Loiter with oscillation a few seconds after engaging Loiter mode.

I’m attaching my latest logs if anyone can help me with these two problems.

Thanks in advance :slight_smile:

Welcome to the community o/

Have a look at this guide How to methodically tune (almost) any multicopter using ArduCopter 4.4.x and do everything that you didn’t do so far.

Ask again if your problems persist after that.
