i was wondering if any 1 can help me with my tail,,i use a sk540 fbl controller which wants to see zero degrees on the tail so thats how i set it up and it was fine apart from a slight tail wag,,ive now set it as per the synergy manual with 5 degrees offset in the tail and it holds much better but on spool up the tail kick right 45 degrees and slowly comes back when the head is up to speed
