Issue was with power brick which came as part of Cube Orange Module.

Replaced it with basic YRRC V 1.2 power module by changing connectors compatible to cube module.

Attached Loiter mode logs in almost no breeze with Battery monitoring enabled. Plz note Have updated to 10" Props from 9". Though couldn’t observe much yaw but not sure it was due to lack of breeze or compass behaving well or COUT for motors not maxing out due to lack of breeze.

Manual observation during loitering, the Octaquad-x gained around 1m to 1.5m height but CTUN’s alt is nominal.

What extra tuning is required. want to mount back rp-lidar and range finder module and test this issue is not present in loiter mode.

Thanks for all the inputs so far
