Hi Pete,

I've just bought the 10 tooth tail but not fitted it yet.
Was running 95mm KBDD tails and downsized to 92mm and it feels much better related to head speed, running N1750, Idle1 1850, idle2 1950 (GR6.4 and rudd 20% expo). I don't auto yet so maybe the bigger blades and slower tail are better suited to autos but for now it feels about right in the air.

Thanks for that, I think my gv1 is set at similar head speeds at the moment, I need to get a little more air time on mine I think, 92mm blades have always worked ok in the past on this size heli for me. I will do some testing and see how it goes.
