Us old timers used to have to double clutch some of the now older antique cars. this isn't quite so bad ... don't have to move leaver slowly out of gear ... but its good to stop in neutral a couple of seconds before changing direction. then advance a small bit to get the thunk ... then wham it once the blades have hit the stops.
in an emergency you do what you have to do. remembering that you probably need double revs to equal prop power in rev.
