JR is not sensitive to long leads. The only devices I would suggest are the new JR RF filters, part numbers JRPA028 for a snap style, and JRPA029 for a ring style. With these, you simply wrap an extention around it a couple of times, and it reduces the noise that is transmitted to the receiver from the extension. Be sure that your servos are not mounted too rigidly, i.e. screws too tight or mounting rails too tight against the servo. Also make sure that there is no slop in the control system, and that your hinges are secure, slop free, and easy to move.
