Just a refresher for all. I had a slow responding left stick. After reading all the threads (especially from Steve) it looks like dirty or corroded pots were the cause. I fly my H exclusively over the ocean and I'm not surprised this happened. I was not comfortable just spraying the product in the two access holes behind the ST16 so, I attempted to disassemble the controller. Of course, my luck the one hex nut in the middle - the tiniest one - I couldn't get off. I was missing the one hex needed! 
So I went ahead and sprayed some CRC Plastic safe in both access holes while stirring the joy sticks. After letting them dry...problem was solved! Hardware monitor confirmed 100% contact now for yaw! I went ahead and cleaned all the motors too.
This stuff is amazing. My instinct tells me, getting any electronic component wet is a no no. I plan to disassemble the chassis soon and clean up all the hardware inside including the battery contacts. Do you think it will be safe to just spray a few burst into the battery bay (battery uninstalled of course) to clean up any corrosion in there? Appreciate everyone's feedback and wisdom to solve my slow stick issue.
