Jamie, years ago when I bought my Nobler ARF, I replaced it with a complete Tom Morris system. At that time Tom made control systems for most of the more popular stunters. I dont know if Tom still makes them or not. You can buy the components for a system from several places. Eric Rule at RSM has all of the components to replace the Chinese system as well. When you start getting into CF push rods, Ball links, Titanium or SS push rod ends, CF bellcranks etc, the price does escalate for those quality components. If you are looking for a control system that is specifically made for the Nobler, I would call Tom Morris. He made mine. I think I paid around $35.00 for it back then.
