I was flying only giant scale from 120cc/100+" wingspan and up to the 170cc size, hardcore 3D with multiple sponsors. The expectations of traveling to all the big events and pushing the boundaries too far just got to be too much. It was getting expensive throwing $5k+ worth of airplane at the ground and not always missing. Then the FAA stepped in with all the "drone" garbage. That was enough for me to put it down. I get enough of them flying the real ones. Don't regret it a bit. Saved enough money to buy a boat. Still dream of owning my own aerobatic plane some day. I'll never be able to get flying out of my system.
