Hi Updated to 3.6 firmware and running beta MP. Basic tuning only shows one line. Roll/Pitch Sensitivity. If I fall back to 3.5 the menu shows correctly.
Copter 3.6 has different tuning parameters, just like explained in the release notes.
Mission planner has not implemented then yet because 3.6 is just a release candidate, and not a final version yet. Please be patient, MP will implement these at some point.
