I recently flash Arducopter 3.6.5 to my Open Pilot Revo board running ChibiOS. The Revo is installed in a 250 size quad. The quad behaves quite normal and steady in STABILIZE mode, but experience obvious TBE when switched to LOITER mode.
Pls see this link for the quad photo :- https://drive.google.com/file/d/1mpdAmyfDwooeez2TvZGp2nWvVWsNFaqU/view?usp=sharing
The param is also attached for trouble shoot.Quad 250.param (13.8 KB)
Thank you for any help.
