never noticed it before, but the tail hub on the 50 v2 is aluminum and not stainless steel. needless to say, it sheered off in flight and caused some pretty good damage.

Yikes! Thanks for the heads up.

BTW - Isn't the R30/50 tail hub aluminum as well? Different design maybe?

i dont think so, most all other manufacturers use stainless steel for the hub.

Dug through some old Raptor 30 parts and found the aluminum one. The one that has the long set screws that hold it in place:

BTW - Where did the Frenzy hub fail?

dont think that one is aluminum, it looks like its stainless

the frenzy hub failed towards the center of the hub, it shot that blade and grip a good 50 yards out, lol.

All of the early raptors had aluminum hubs. But the problem was there was a long setscrew that threaded in and the bearings and grips rode on the set screw. It was too much force for just a few mm of threads to hold over time and the setscrew would pull out of the hub. The hub on the Frenzy is a one piece hub with a bolt and was originally designed for Gohbee 50/90's I have and others been running the same tail system for years with no issues. Either you had a defective hub with a crack or it was a flawed piece of aluminum. You can always install a Trex 600 hub and blade grips to your frenzy it bolts right on also.

Raptor 50 uses SS hub with angular bearings, very strong tail and no play.
