Has anyone tried this main gear from Hong Kong? Any luck with it?

My experience with cheaper replacement gears has been that they warp when you bolt them down on the hub. Don't know about these in particular, but a main gear that wobbles sends some serious vibes to the sensors of your gyros. My EXI 450 pro had some serious vibes coming from the main drive and my tail was always wagging. If I turned the gain up it would wag faster. If I turned the gain down, it would wag slower then blow out on harder collective maneuvers. Replaced with Align parts and it had less visible wobble and the vbar showed less frequency spikes on the main drive. Almost fixed it entirely and was much more solid. Replaced the futaba 9650 with a high speed Outrage tail servo and it is now rock solid.

High Voltage just works better
