I'm going to take a guess... you touched the ground with the tail. It was light enough not to strip the "fuse" but hard enough to damage the teeth. On the next flight the gears stripped.

since the "fuse" 17T gear costs like $3, its an item that should be replaced always after a crash. I broke mine 3 times now.

Don't really see this like a design issue but rather an "overlooked item" after a crash.

There might be a possibility of your boom sliding out a little bit. Which caused the gear mesh to loosen and ended up in breaking the gears?

As on my routine checkup, I found the same gears not to be moving smoothly as they always did, and concluded that the gear slipped out. Just got it up right straight and worked out well for me. Well it wasn’t up in the air so didn’t faced such a problem; always check my machine on bench after every 20 flights / 2 Gallons.

I doubt it. Remember that the boom sliding out wouldn't not change the mesh of the crown gears and they are stripped in the pictures. The only way to strip those gears are with a sudden stop and the 17T gear not vaporizing immediately.

Yeah, that 17T pinion stripped looks awfully familiar when I hit my T/R. It is the first thing to go like Tony says. It has to be a T/R strike.

Looks like a case where a belt drive is more forgiving than a TT setup.

If one isn't able to keep his heli's butt out of the dirt then by all means, get a belt. There is a conversion sold by JR for the vibe 50.

However, I do prefer the ease of setup and maintenance of the TT far more than any belt. Do I need to replace the 17T gear after a crash? Yes but I can live with that.

I don't understand how people can badmouth TT designs because they cant keep their nose down during landings..
It's not an airplane.. don't flare so much =P or run shorter tail blades..

as for the damage yup looks like a missed tail hit damage.
or crash damage.

Not sure if your post was aimed at me, but I wasn't bad mouthing TT systems.

However, like everything in life, there are pros and cons to any and every system.

By and large, many pilots find belt systems less troublesome than TT systems.

Nobody is disputing belt vs TT here I think. They both have pros and cons. In the end, everybody will have a personal preference. Mine is the TT for all reasons I mentioned above

This happened to me as well...
I had the same problem with my Vibe 50 when I first flew it. I could not figure out what caused it until I checked my manual over and over again. I realized that I miss understood the picture when installing the bearing at the top of the gears. I put the bearing in upside down alowing a small amount of play in the gears. When I flew inverted, the gears disengaged and stripped. Needless to say, it was and EXPENSIVE goof on my part. When I rebuilt my Vibe and flipped my bearing, it was a noticable difference.

Check your bearing and make sure you did not do what I did. It is an easy thing to do "twice" if you thought you had it right the first time...

If you touch my heli, I'll triangle choke you!

Looking at the damage on the first photos I would say the problem came from the tail end, you can trace the impact. If any of the bevel gears failed on there own it wouldnt cause damage to the other gears. If you stopped the tail suddenly it would damage all the gears in the line.
