Upon which the AMA membership guidelines and Safety Code were based:
AMA Safety Code, Item 2:
2) I will not fly my model higher than approximately 400 feet within 3
miles of an airport without notifying the airport operator. I will
give right-of-way and avoid flying in the proximity of fullscale
aircraft. Where necessary, an observer shall be utilized to supervise
flying to avoid having models fly in the proximity of full-scale
aircraft.

and any rules may be imposed by the city or the manager of the airport..
we have the ability to fly from the airport with a set of rules that are
added to our current club rules for flying sites.

Note that it's advisory -- not law. Still, mostly common sense.
Interesting how it says `Do not fly model aircraft higher than 400
feet above the surface.', but then goes into details about what to do
if near an airport. The AMA version says to not go over 400 feet if
near an airport ...
So does the FAA think we should not fly over 400 feet high anywhere,
or only if near an airport?

I fly at the local airport(no trees!)
Must have a spotter.
Now, if my .40 to .60 size plane is high enough to become a speck, how high
do you think that is?
I'm not a good judge.

Put the airplane on the ground 400 feet away and note it's 'size'. Then try
to duplicate that 'size' in the sky. That'll give you an idea of how high
400' is. It's not very high!

Good idea. Also while you are doing this have someone stand the plane
on its wing tip so that the bottom is to you. Look at the plane with
your antenna in the middle of the wing. Take tape and mark the wing
span on your antenna. When you are flying compare the size of the wing
to the taped marks on the antenna. When they ar equal, you are then
the same distance high that you were horizonal.
This will give you an idea. 400 feet is not high for a 1/3 scale but
is real high for a 1/2A plane. It's all relative.
