Replaced the tail motor now need help with new problem

[Sash31]

As the title says I replaced the tail boom and motor and seemed fine but, now when I give it any rudder input and stop the heli keeps spinning and I have to give it rudder in the opposite direction to counter act the tail spin! Sometimes it even does it in a hover, it'll be tail in and then all of a sudden it'll rotate 90 degrees to nose right...I've checked the motor and everything seems fine and nothing seems outta place on the board and also have made sure that it's plugged in and hasn't come loose.

So if anyone could give me a hand if you've experienced this yourself or might have an idea how to fix I'd greatly appreciate it, cuz so far it feels like I'm trying to get this thing working lol
Thx

Sounds like the typical V2 vibe issue. Check your heli for any vibes or bent/damaged parts.

I'll do that and maybe put up a video later
