Does anyone know where you can find lighter control stick springs for the Futaba 9 CAP. I have removed the back of the transmitter and lightened the stick springs as much as possible but even at the lightest setting, they are still too heavy for my taste. I am used to the adjustability of the Hitec transmitters control sticks which can be made very light. Radio South has heavy duty springs advertised on their website but I see nothing for lighter springs.
