Futaba BS152 centre hunting
Hi All,
We started my friends brand new Krill Composite DA 110cc today and noticed a very funny servo hunting problem on the elevators. The elevators have BS152 rutabagas servo.
Both the elevators flutter a lot, one side ore then the other. But when the fuselage is tilted to a knife edge position, the flutter stops. But when we bring the fuselage back to normal or inverted state and give any side command to the elevators, it starts fluttering again when coming back to the centre.
It seems that it's trying to search for the centre to lock and cannot find it.
Can someone please advise what can be happening?
Thx a lot
