Anyone else think that there is a broken bolt in that hub ? That will be why the plastic guide gave up the ghost.

The new kits have a pinned tail now dont they ?

I'd say a spindle bolt snapped and slung the tail gear off.

I think I saw the plastic pin sheared off on this one.
I lost a tail blade once and it twisted the tail gear but it stayed on long enough to land.

When a TR grip bolt shears off it usually removes the entire tail rotor transmission from the heli, ask me how I know. Looks like thats probably what happened before the crash

I have already seen something like this before here on RR, I think Matt Botos was involved or around. Lucky indeed.

When a tail grip bolt shears off, it's usually going to cause enough imbalance to turn the tail rotor shaft into a pretzel. This look like the entire tail assembly blew off when it happened.

Another thing I've noticed about crashes is that CF booms tend to give pretty easily, at least more easily than a metal key. Hmmm, might better to run plastic for the keyed spacer.

Wow, 2 very inexpensive crashes - lol. That's what I meant - best case scanrio is to have it blow the entire case off.

Is the key piece plastic or metal on the 700. I have upgraded metal ones on my 450 and 600. My 600 is so old it doesn't have neither (but I added my own 'pin'. PC, I can see where it ripped your boom up.

The last time it happened on my 500 it caused a lot of damage. I was using stainless M2 screws, too.

I've also had it happen on a 500-size scale setup where it immediately snapped the 45-degree scorpion tail and really helped minimize the damages.
