I begin by mechanically setting the tail pitch slider in the middle of the range which in most well designed helicopters corresponds to correct hover tail pitch.
I make sure my radio and trims zero to correspond to the FBL program, (see DIAGNOSE menu)
Then I also check for any stupid tail mixing the radio could have in its default program and take it out if any. This is actually step 1 in the whole process.
Trimming tail in flight: If I see a consistent
drift I adjust that long thing called "tail pushrod" accordingly (really technical stuff LOL) until no more drift. Re-check program tail endpoints to ensure no binding if you went to the stops.
(I actually use a pitch gage on the tail to make sure I am not setting too much pitch and stall the t/r)
If the drift continues I look for something in the tail drive that may cause a t/r slip, or pitch slider excessive friction.
Sorry I did not see your other post, Speed Cup work is kicking my arse.
You said you had a quick tail kick every once in a while. My best guess
is the drivetrain or tail may be experiencing a harmonic vibration that is causing it.
