Quick Stop Drone Valves

Designed by Bruce Hitchings of Achiltibuie Highland Reeds, these plugs fit snugly into the bottom of the drone stocks (works best with a zipper bag, though they can work with sealed synthetic bags). They function like a flapper valve for the drones. As long as air pressure is maintained going into the drones, they're open. When pressure is stopped, they shut immediately and prevent any possibility of trailing drones. Perfect cutoffs every time! They also allow you to fill the bag very full before starting.

The Quick Stop valves feature a screw adjustment, rather than an elastic band as on many other brands of valves. This ensures precise adjustment and more reliable operation.

The valves will work with the Ross Cannister system as well, and can be adjusted down the stock with a screwdriver - removing the drone hoses is not required (after initial installation).
