This is a heavier-weight spring for certain Futaba transmitter gimbals. For the modeler who wants a stiffer 'snappier' feel to the radio's response.
Includes: 3 metal springs (elevator, aileron and rudder)
Requires: Compatible transmitter, transmitter disassembly for installation
Note: These are not to be used on the 14mz/12z as they are too heavy. Modification of your transmitter in any manner voids the transmitter' warranty. For spring installation into a transmitter while under warranty, please send the radio to the Futaba Service Center. If Futaba is not performing the installation for you, Futaba cannot guarantee the workmanship of the installation. Therefore, Futaba is not liable in any manner for any damage done to the transmitter as result of the installation of these springs.
