I'd have thought..

Model =

"A small object, usually built to scale, that represents in detail another,
often larger object." rather fits the bill.

Proportionally in scale with other 'full size' (whatever that means)
planes?Check.
Wings? Check.
Prop? Check
Fuselage? Check.
Tail empenage? Check
Four forces acting on it? Check
Control surfaces? Check.
Does it fly? Check
Does it stall? Check
Affected by normal laws and principals? Check.


Versus:

Toy =
1.. An object for children to play with.
2.. Something of little importance; a trifle.
3.. An amusement; a pastime: thought of the business as a toy.

Hmm, that could be aeroplanes of ANY size and scale to some folk.

Well I guess I fly Indoor rubber powered duration airplanes. Airplanes that
weigh about a gram and fly in a blimp hangar for 30 -40 minutes or more under
rubber power and NO radio control.If it's a toy a lot of us are real serious
about our "toys" during the National competitions which are coming up :-)

I never considered a model that weighs a gram and is built with select balsa
that has the weight per cubic foot ,grain direction , Young's modulous
calculated and dimensions within .001" , where glue joints are weighed and a 18"
diameter variable pitch prop that weighs half a gram and changes pitch during
flight a toy. Maybe to some it is a toy but I bet my rubber band powered toy
will beat your rubber band powered toy. LOL!! So I guess it's what ever floats
your boat .

I've seen some of those things.
Pretty awesome machines.

I've built lots of rubber band powered balsa airplanes.

The toughest by far is the helicopter.
Fully articulated Hiller style setup -- 15" rotor span.
Powered Tail Rotor.
All balsa, too!

It's only trick is once around the pattern
with a high rate decent to landing.
(It doesn't autorotate
And I've never seen it really hover stationary.

To the great unwashed masses it look like a toy.

To those in the know, it's damned near a miracle.

Eye of the beholder, I guess.
