Y6B build yaw drift, slow rate

OK so I built my 1st Y6B and had the maiden flight today. It gets up and flies but I noticed 2 things.

It held position in POSHOLD well but it was yawing around the yaw axis and a very slow rate. It was almost like it was weather vaining in to the wind

Applying yaw with the radio resulted in very slow yaw rate.

Any one have any ideas.

Hi @Barry_Bolton,

Does this issue correspond to your another thread? If yes, can we continue the discussion there?

Lets go through the LOGS for the crash first. I might just make a normal hex once the crash issues have been sorted out.
