I have the 5's on my MGT.
I bash extreamly hard, never bent a shaft, But I always have to refill them.
In my opinion, There more for show, or street driving.
Also, I don't think they make them for the Revo yet.
I had a set on my CyberMaxx and beat the crap out if it. I still have the shocks and they are like new. Its weird, some people bend the hell out of them and others dont.
I watched a dude totally trash 4 out of the 8 within an hour of their maiden beating. Two of them busted apart at the threads, one got a bent shaft and the 4th ripped apart from the inside.
Granted, he was extremely brutal, but mostly high speed 8 foot air and bad landings... really bad.
I'm uploading a vid to rcpics so you can see what they didn't live through.
Link to vid. I think this was the first half, but I put stills of his busted up maxx in the beginning. It's crappy quality. It was before I figured out that I had windows movie maker...
