Tx stick smoothness in Futaba 10J

Improvement of smoothness on Gimbals stick in Futaba 10J transmitter has remarkably recommended by applying the carbon led powder between neutral guiding lever surface and guiding pin.
According to my experience on the shutter trigger when I disassembled Leica M3 old model, several materials were applied at that portion,  Teflon powder Microflon, 2 Molybdenum sulfate, and Carbon Led Graphite Led powder.
Carbon led graphite powder had some advantage among the materials tested especially in the condition of short distance, slow movement and relatively high pressured slipping scenery.
This same concept was applied on the transmitter gimbals construction because I had been suffered from some uneven movement phenomena in aileron, elevator and rudder stick actions. Slipping resistor changes and the stick movement transition is not always acceptable to set and keep the stick angular position when vertical flight. This is why I determined to replace the lubricating materials from ordinary Silicon grease to Carbon graphite powder.
Now I have no complaint on the gimbals stick movement in 10J transmitter as a matter of fact. Next actual flight would prove that the change of lubricant should be effective enough to compete with the other applicants who all are armed with the most sophisticated proportional system 18MZ. Defeating higher weapon with the cheaper arm is my way.
The reliability of the Radios between them are the same however cheaper it may be, so the requirement at the competition scenery is nothing but the skill of the pilot, eye sight to the moving thing and my own quick finger reactive movements.
