I'm learning to fly my first 6ch heli. It's a HK-450GT PRO V2. However I must not have put enough or forgot to put thread lock on one of the tail rotor grips, the one that bolts to the hub (still new to all the terms). Anyways, while spooling up, the thing explodes off and breaks. My problem is I can't find a replacement assembly. I understand this is a clone of a T-rex model and was wondering if it would be easier to find a tail assembly for that and switch it over.
