Depends on your visual acuity, wingspan, orientation and sky conditions. "YMMV".
Use trig for altitude calculations. a=b(tan alpha) .

Hi All,
I was just wondering, how high can I fly my glider before I lose radio
control??? Some say about 1 mile?
How does a 100ft. wingspan glider look from a mile up in the sky? Or how
can I estimate the altitude?
