Years back, I flew sailplanes. ridge soaring in the Columbia Gorge. I had great days in the air...aerobatics and chasing hawks, sometimes just floating high above the valley floor. Recently, my wife wanted to get me a heli for my birthday. She had no idea what she started! Have spent far more money than she envisioned, but it's starting to pay off. Electric helicopters are awesome. Thanks to this forum and RCGroups, plus help from Ron Lund, I'm getting the hang of it. Lots of research, a few headaches, and plenty of tinkering have yielded a bird that promises to be quite entertaining, especially when I get good enough to put a GoPro on it! And there will be a second TREX in the hangar sometime soon.
