RE: What is cubic wing loading????
The formula is Weight of model in ounces divided by the wing area in sq. Ft raised to the 1.5 power. In your case 10.5 times 16 devided by 6.18 raised to the 1.5 power which, if my math is correct is equal to 10.9. This should be a reasonably good flyer but will have to land slightly fast. A value of 7 would be a real floater.
