Would have loved to stay longer as it was a great morning to fly but a bald eagle had other plans. Thought I was going to lose the XSP about 1\4 mile out. Saw him up above the quad just circling and each circle he got lower and lower. I put it into Atti mode and booted back across the river hoping he would just leave but he gave chase and never gave up till he saw me on the ground and turned and few off. I was pretty worried as I have never had one come so close before.
