Interesting as I was given a "non-working" Hubsan X4 h107 today. A quick glance indicated a bad crash as 3 of the 4 legs had their shocks "popped", and 3 of the propellers have damaged ends. There is no battery so I'll need to order a couple tomorrow. Is there a preferred brand or supplier for these lipo batteries? I'll need to buy some propellers too and a prop wrench. Other than that, it looks as if it might work with these parts if I'm lucky ;-)
