I am a recipient of a Typhoon H that was my fathers. He only flew it twice before getting grounded. I just realized that there is no charger and the two batteries have some swelling going on. My question is this, is it worth purchasing what I need to get it airborne, or should I sell as is. My concern is if Yuneec has any support if needed. Thanks.
Couple things come to mind . . . .
A used Typhoon H with charger and useful batteries and even some extras will only fetch around four to five hundred bucks. With no batteries and no charger, substantially less. So if you sold as is and you may get 300 bucks - what other drone would you get with that amount that has all the features of the Typhoon H? Not many.
Even when Yuneec has some semblance of customer support here in the states, you were likely to find better; one-on-one guidance from real pilots with a massive amounts of experience, right here on this forum - and you still can. As mentioned, for parts and other service we got Yuneec skins. Personally I feel better about support for our birds now, than I did just a year or so ago.
While I still fly my H Plus I have ventured to one of the 'other' brands and trust me, the grass ain't so green as it appears.

I'll just say one (or two), words about that . . . .Nanny-ware
Get a couple batteries and a charger, stick around and enjoy.
