I've ordered yesterday it's younger brother, quadro, for $11. This seemed to me like a good cheap frame for start and learning.

Here's what happened to mine:

Crashed from about 6" or 8" :(

Sam, was it a hard crash?

HK doesn't have spare parts, but you can get 550 arms from RCTimer: $4.95 each. 

Oh, I'd weigh and measure the RCTimer arms against the HK ones before actually flying.  Who knows if they are made the same or not.

Very cool!  It’s great to see China ripping off China!!

It sure brings prices down. The ultimate in free enterprise.

If it's any consolation, the original DJI FW550 isn't especially good either. The material is to soft, meaning they can take a beating but you also get lots of flex and vibration in the arms during flying.

I think in most cases flex reduces vibration.

Not quite as cheap, but I was checking this one out lately.

I wonder what the best < $100 hexa frame is right now.  One that you can actually get parts for.  It was nice to be able to print the old copters out at ponoko.

@john arne

full ack :-)

Cre8it: You are thinking about shock absorbers/vibration dampeners, but when the entire arm flexes you get oscillations amplifying the vibration.
