HX Dragonfly 251
The kind of helicopter I have is an “HX Dragonfly 251.”
It’s looking like the only place online that sells the thing is in Japan. Hmmm. This is going to make finding replacement parts tricky.
UPDATE: The HX Dragonfly 251 is the equivalent of the Syma 9093 Dragonfly helicopter. You can get spare parts at Raidentech.
