Care to take some photos or video? Check the tail system is free running. The tail blades closest to the heli center should rotate up towards the main rotor downwash when the main rotor is spun clockwise.

If it is tail belt drive it should only have 1/4 turn in the belt.

Have you got the belt twistered in the right direction? When viewed from the right hand side of the heli the blades should turn anti clockwise.

Position the blades in the12/6oclock and fold the bottom one rearwards,it should move as if it were a boat rudder when you move the stick.

Ie rudder stick right the blade rearmost point moves right,turning the nose of the heli right.

If you push left stick and the tail goes left as you say, then the nose is going right.

Tail control is the wrong way around.

[james and]

it was ok before the crash do i need to change the setting

[Steve]

Left rudder must push the nose left, not the tail left. You steer a heli by the nose, not the tail. Left rudder steers it around a left corner, not a right one.

[james and]

yes its going the wrong way , ie push left stick to the right the nose gos to the left

[james and]

sorry push left stick right nose go,s left
