We've now released Bilmpduino with the option to get the RC kit, LiPo battery and charger all in one. The only thing you need beyond that to have a fully autonomous or RC-controlled blimp is helium from a party balloon kit (available at Target or any party store).

The RC gear is a 4 Channel 2.4Mhz transmitter and receiver from Hobbyking and the LiPo is a very small and light Rhino 460mah unit. The included charger is a Turnigy 2-3 cell balancing charger with 12v leads for car use. The total package, with the Blimpduino kit, RC unit, battery and charger is $155.99 or just $109.90 for Blimpduino with the battery and charger (you supply your own RC gear).

You can buy it here!
