I slope fly r/c Sailplanes @ our 900 ft. Mt. Trashmore here in Cedar Rapids, once in awhile,, when the city let's us up there to fly.
It is right by the river, & we often have an abundance of Bald Eagles.
A pic of my 2 meter DG -1000 flying with a Bald Eagle, taken around 6 years ago.
He flew with me for around 4 minutes, & was pretty much just checking me out.
Wing span on the plane is 6.5 ft., & am figuring the span on the Eagle @ around 2/3 of that.
