RE: 1/4 Scale F4U-1A Don Smith Plans Build
I got it from Bobby at Cactus Aviation and I believe it's 52 ozs. It looks like a huge water bottle from a bike. He has the nice filler and all the other fittings you will need. Throw some business his way. Very nice person to deal with. He also sells the 3W engines here in the US if you didn't already know that.
