I've been using a Turnigy 9X for some years and know how to change the springs to change mode actions.s But I've ordered a Flysky TS-6 as a backup should my only Turnigy 9X die . I have flysky i6 but the rang eis somewhat limited. My question, before they deliver the TS-6, does it use springs to set self-centering as the T 9X does? I see the i6 just swaps modules from within and set via the screen. Hope this makes sense. I now only operate rc sailboats so crashes are no longer a problem.
