`I built this heli back in May 2018 It flew great! Then in June I was doing loops to close to ground and the ground came up and smacked me. LOL I practically replace the entire heli. New main shaft, spindle, tail boom, bearings, spur gear etc. The only thing that is original is the frames. it would have been less costly to just have bought a new kit. My setup is. OS 105hz-r, Align DS 615 servos on cyclic, DS 655 rudder, Ikon 2 flybarless controller, and Futaba 14sh. Since the rebuild I now have this shake in the skids. Nothing seems to get rid of it. When I first lift off into a hover, it seems normal. Then after a short period of around 30 seconds it begins this shake, seen mainly from the skids moving. And worsens the longer you stay up. I have replaced everything in the head, except for the swash plate. The servos are new as well. I finally have come to the conclusion that there must be something wrong with the Ikon2. This will be its second crash. Once on a trex 700 and now the Synergy N7. If someone else has a better solution on what else I may have missed, I would be grateful for your advice.
