Irish Lord99 I don't know if you are kidding or not but you have to fill the tank with air using a bicycle pump or a purpose built pump like you get from Robart, or an 12 volt electric pump, some of which are quite small and can be operated with a 3s 2100 mah lipo (just don't leave it on an puff a battery).
don't be cruel u lot. irish this is just a empty pressure storage cylinder. u have to buy the other bits (hose, valves etc) to pump it up with a eg* bicycle pump.u might be better off with the electric retracts sold here. lot simpler to set up
hey everyone, i was just wondering how these bottles fill up?is there a little air compressor available or something?

Silly low price, great value as usual from Hobby King. I have fitted mine to a Kyosho 40 sized P51 and it sits behind the servo tray under the push rods. It holds enough pressure to operate the retracts 5 or 6 times with out loss of operating pressure. Very happy.
