    GY401 odd tail wagging

    On the trex 450 I had a tail wag it was very precise it would be fine till I put any rudder input then it wags left then right only about 5 degrees each way right then left and so on till I landed and took off again?

    GY401 with a futaba 3110 servo is this a delay issue?

    The heli was new and the linkage was silky?

    Thanks in advance

      Thats what I thought I did take it quite low But I have to set up the new TX tonight so I will try again...

      It wasn't like any tail wag I have had before it on the raptor it was like a gentel wag but on this it was hard and made a funny noise?

      It was also the first flight of the 450 so it could have been some thing else like the belt?
