I flew it on 4 different batteries and all did the same thing. Any ideas what causes this?
mine does that sometimes in a hard banking turn. it's like it loses signal for a split second, but recovers before it has any effect on flight surfaces. only throtlr is affected.
if you are in cold weather, that may cause it also.
