A 73 inch CAP under 11 pounds? Sheesh that's light. The Moki 1.80 would be a satellite launcher in that ARF. How does it fly? Can it 3D at all? The Moki would add almost a pound to it so it would be more like 11.5 pounds. The Saito will require a 24 ounce tank and the Moki will need only a 16 oz tank. So even though the Moki is heavier the fuel it carries is lighter by 1/2 pound. So the net increase in flying weight is only 1/2 pound.
