Hi guys. I just wanted to put in a good word for Yogi and one of his products here. I purchased his helicopter cyclic gimbal several years ago and I love it. It has held up great and has a fantastic feel to it. The design uses highly accurate hall effect sensors and hydraulic dampers like those for a radio controlled car. You can choose to keep springs on the dampers for a little bit of centering force or you can remove them for a totally “limp” stick feel which I prefer with just the damping which feels great.
