Hey buddy! I hope the helicopter is ok after that little spill. Be sure to double check your feathering shaft.
Let's try starting from the beginning here. I think you said that you have your gyro gain set to +80. Let's drop that setting down to -30. Hopefully that will put us into Rate Mode. Find a nice smooth parking lot or driveway with plenty of room to drift around. Let's keep the training gear on. While in Rate Mode, spin the helicopter up but don't let it lift off the ground. If the helicopter still spins, we need to either lengthen or shorten the tail push rod. Make an adjustment, either lengthen or shorten, and then spin the helicopter up again but don't let it lift off the ground. Take note if the helicopter spun around faster or slower. If it spun around faster then we need to adjust the tail push rod the other direction. If the helicopter spun around slower, then we are going in the right direction and you'll need to adjust the push rod in that same direction. Let's try to get the tail locked in while in Rate Mode. Once we've done that, then we'll go back to Heading Hold Mode and fine tune the tail.
