Spring flipper locking system

Make one. Do some reading up on quick release mechanisms. Look at things like cross bows

I can see how it's constructed, but how would I bring the weapon down? Do actuators have a function to be disabled from the transmitter, if wired correctly?

I imagine it would be easier making a winch sort of thing with a clutch so you can disengage the motor allowing the winch to "freewheel" letting out the wire. You could design the clutch so that if the motor turns in one direction it engages but if it turns in the other direction it releases.
