450 tail prob

[supamansuper]

When I've been spooling up the 450 recently I've noticed the tail vibrates up and down when I start spooling up but stops vibrating as the head gets faster.Is this normal if not any ideas to what it could be?

Pretty normal, just up the headspeed

Not wanting to sound stupid but,Do you mean up the throttle curve?
I have it set as per manual at 0,40,65,85,100 What do you suggest to change it to?

^^ or you may have tighten the rotor blades too firmly - just undo the screw less that a 1/4 turn and you may find all that shaking gone.

Your throttle curve is OK; may be you could increase 40 to 60 and 65 to75

If it's only occurring as you're spooling up it's not a problem. Maybe it's being exacerbated by ground resonance; maybe try pulling your blades out straighter before starting?
