While training a friend how to fly his brand new I1, I was at the controls when I had a flyaway. We were in a park he took me to that had what he said was an inactive radardome. Turns out it was active and I lost control of the I1. Since I was at the controls, I said I would have it repaired at my expense. He told me he had insurance that could cover it, but didn't want to use it. Then, after I contacted a repair company (Drone-Works), he told me he was uncomfortable with getting a repaired one back and demanded a new replacement. I bought one and am going to give it to him (a complete new I1 with battery, controller, case, etc.). Now he says I cannot have the wrecked one and is demanding I give it back to him as he says I have no salvage rights like an insurance company would. Thoughts?
