I test flew my Bad Boy V2 today and generally it went OK but not brilliant.

The main problem was severe wing rock in the harrier and hover.

C/g as per instructions.
Max movement on all surfaces.
60% expo.
53 2 stroke / 13x4 APC prop.

The model will do awesome inverted climbing flat spins, but..... Hover is terrible due to the wing rock.

Anybody any ideas as to the cause.

Many thanks


Simon
