The RCS module provides for ramped speed control. Partial stick movement off centre provides a SLOW speed change. Full stick movement should initiate a FAST speed change. In my case however the fast option was not being
selected. The easiest solution for me was to fit a, centre off, three position toggle switch to the Tx case.
This then gives the fast change, which can be used in an emergency stop.
I had a problem as well with the triggering of the engine sound unit. It so happens that when you program the RCS module for a latched output, as opposed to a momentary one, it requires more ‘servo throw’ than the Tx provided, to set the
output to ON or OFF.
