380/420 Blade 330S

[Wyattl]

Hello,
I recently bought the horizon lobby 330s upgrading from 230s. While I’m getting used to it I’m still in safe mode. I have noticed that i have tail wag even at low throttle. Is there a way to set trim on the transmitter ( Spektrum DXE) this to fix it?
Additionally, I hit the tail rotors on the ground. Could this also cause the tail wag?
Any suggestions would help
Thanks

The tail strike could be the cause of the wag, did it wage prior to the strike ?
Check that the shaft is not bend and the the slider moves freely.

More than likely the cause is low head speed if it's only happening at low throttle, to test it try a throttle curve of Normal= 0,80,80,80 I doubt that you will still have wag.
