450 Tail rotor hub failure
I was given a T-rex 450 with almost all the "bling" upgrades there is, full metal head ect.
Here is my hassle though, I have now had 2 failures of the pivot bolt shearing of that holds on the tail rotor grip. Luckely both times no damage to the heli.
One was a full metal unit the other was the plastic one, same failure on both - the 2mm bolt lost it's head and the grip departed the hub.
Is this a common thing with 450 T-rex?? Could the rotor speed be to high for the hub assembly?
I can easly get a replacement of the whole unit fro HK, just wondering what would cause the repeat failures.
Any ideas or advice please.

No not realy allot more than I would expect. I didn't build this heli, maybe someone before me somehow damaged the bolts by over tightning them....
I will buy a new complete unit from HK, was just wondering if there are any particular brands I should rather avoid?
