I am a very new operator, and I am flying a knockoff rig from a brand I do not care to write down here because I am not yet in a place to drop $5,000+ on a rig.
I am aware that running a cheap rig is not helping me, however given the parameter that it is what I have to work with right now, I'm trying to track down the likely cause of an issue I am seeing: I have my rig built with a fairly light camera (though I have tried adding weight to the stage with no real change). I balance the sled static and dynamic, drop is a healthy 2 seconds, etc. Everything feels balanced in general, but when I actually fly the sled it has a tendency to lazily drift a degree or so back and forth when at rest. I can get the arm fairly steady in a stationary position but the gimbal just kinda keeps drifting around. The drift is more or less circular, not listing towards a specific direction, and everything else seems to match what I have seen in demos and guides. I would intuitively think that this was caused by a top-heavy sled, but the sled drops correctly and this happens even when I fly almost no weight on the stage or with a lot of weight at the bottom of the sled.
Is this likely just the result of a cheap gimbal, or are there common causes of this behavior in how the rig is built and balanced? I don't trust this rig to perform like a real steadicam, but I also don't want to bake operator error into my practice and just blame it on cheap equipment.
