From what I`ve read ,the MCAS operates when flaps are `UP`...What is the flap limiting speed,and does the system(MCAS) depend on the flap lever position only...?
I used to fly C-130,which had power controls,but power to the rudderboost was limited when the flaps were UP,but full hydraulic power beyond 20 deg,primarily to prevent overstressing the fin at `high speed`,but cover the lower speed asymmetric case requiring more rudder...
However,if one was doing `tactical/fighter affiliation/more aggressive flying,one could `cheat` by pulling a c/b for the FLAP hydraulics,and then select the flap lever to 20 deg.This then gave the rudder full hyd.,but the flaps were still `UP`..

I would have thought that the immediate actions drill would have also stated to have reduced speed to perhaps below 300 kts..
