Raptor 50 Tail rotor hub failure
I recently was having a vibration problem in the tail that I have been trouble shooting now for 2 days. So bad in fact the horizontal fin "carbon" cracked on both sides due to vibration. Either I cracked the tail rotor hub on a recent auto, or it has or was cracked causing the vibration until failure today. Luckily I was in a test flight hover when this happend and the grip side that broke went straight into the ground in front of me. hit hold and brought her down easy.

damage? well..a cracked up tail case, blown up slider, maybe a bent tail shaft "gonna replace it while im in there" possible blade grip damage.

So, my question is....

what changes or experiences have you had? and what did you replace it with?

I am building my first Raptor (50 Titan) and so many people warned me that the stock tail hub would give me a problem i put the stainless steel one in during the build.

Need the stock part? Its just sitting in my parts jar!

problem solved
Part # PVO499 I consider it a must have item for raptor. Its a steel hub with threaded steel studs on the end. Its much stonger, instead of aluminum hub with an overly long set screw as you axle. And its only $4.99 (EDIT: I see heliproz gets more than that, it may have gone up in price since I bought mine)
