I was inspecting my machine as always after an afternoon of flying when I noticed the head yoke on my Evo 90 is cracking by the dampners. Part #414385. Thankfully it's only $10 but has anyone else experienced this?

I let a friend fly it yesterday and he was banging on it pretty hard so this is most likely the cause but it I know others are banging theirs just as hard.

Here's the video of him flying it:

Some detailed pics of the crack are here:

If you watch the video you'll notice the engine died during flight because it threw the clunk off the main tank.

Mine cracked too. I bought a new one and so far it is fine. I am using the CX dampers though.
