The wing is not ignored (or we would not bother with one at all). It is just as important on a 3d plane as it is on any other. Just because we stall it for many manouvers does not mean it is not important. Even in a torque roll the wing plays a part in giving stability to the plane.

As for the Flip being heavy are they refering to power to weight ratios? Ie you cant hover as well on a 46 as you would with other "40 size" similar planes? Don't know what weight a Flip usually comes out at.

Looking at the Kyosho web site, says that it should be 5 ot 5.5 lb. With a whopping 930 square inches (as much as some 25% aerobats!) it gives a very low wing loading of 12 - 14 oz per sq ft. Seems pretty good to me.

For my own purposes when looking at wing loading I look to a max of 15 oz/sqft for funfly winged planes (like the flip) and ideally a max of 20 oz/sqft on normal winged planes (like my C50 and C140). I suppose that answers the question, it is about wing loading not weight, though weight is an issue in terms of engine selection, which then raises the weight and increases the loading [&:]
