Just curious, don't see it mentioned often, other than the typical "Drone" discussion. I have a small quadcopter, but can't get real excited about it. I guess since it's not a scale model of anything. Over the years I have sold off all of my nitro stuff and have gone full electric. Brushless motors and Li-Po batteries have revolutionized the hobby. Advances in materials and manufacturing have taken foam construction to new levels in performance and appearance. Any others out there?
