Seems to me I've also seen some alititude restrictions imposed
on RC models flying near full-scale airfields. I think that at my
field (Reservoir Park, Lewiston, NY), we're technically
not supposed to go above 500 feet. Some of the larger
models (~40% scale) apparently can be seen on the radar
screens at Niagara Falls (IAG).

Marty,

A dumb question: other than eyeballing and estimating, how exactly does
someone controlling a RC model know its altitude?
