RE: Wing Loading
The way I understand it, wing loading is a constant relative to the size of the plane;meaning, if your plane has this wing loading, it would have similar flight characteristics to other planes of larger or smaller wingspans that also have the same weight relative to wing area (wing loading). Anything under 18-20 oz./sq.ft will be a floater.
However, since it is a small plane with low weight, wind will be a bigger factor while flying.
