Question: What is the typical capacity of the fuel tanks supplied with VMAR ARF models?

Answer: Generally 300-350ml (10-12oz)

Better Answer: To be sure you will need to determine exact capacity using a measured amount of clean water. Tanks with a plastic stopper cap, two lines and a notch in the front are approx 300ml (10oz) in capacity. Tanks without a notch in the front range up to 315-350ml (11-12oz). For more information please review the specifications for the particular tank of interest.

There are some exceptions: Control Line and small RC ARF's have a 100ml (3.3oz) tank. Dornier DO27 45 ARF's with the squat short tank have a 250ml (8oz) capacity and larger models like the 10 foot span Dehavilland Beaver have a 750ml (26oz) tank.
