WARNING: This plan is old and while it works is small and not particularly great. A new messenger plan Anthony's Lifting Messenger is now online and is recommeneded over this plan.
In any case this messenger is tough and although the sail has been replaced 3 times it is still in use and work since being created in late 1995. I will be leaving this plan online as a reference though I don't expect people to actually use it.
The following are pictures of my ``Mintie Messenger''. Over the past year I have used it to send 2 to 3 minties (paper wrapped lollies) at a time up the kite line, to drop them into the waiting hands of any children in area. Always a big hit.
This was a prototype and if I build a new one, I will give it a bigger sail and hook to allow a larger load to be carried, such as a bag of (wrapped) lollies to be upended, or a teddybear. I would also probably move the sail hinge further toward the front of the kite.
NOTE: The kite photos show a rubber band keeping the release hook closed. I have found this is not really necessary. Nor is it necessary for sail retraction lines as used on Dorf's Ferry. The problem with the latter being that the hinge is not large enough and has a lot of fiction to overcome to work, which means retractor lines are needed.
Here is a photo of the messenger just after launch. The line is
being supported by two UFO (rotor class) kites, which produces a very tight a
kite line at a 30 degree angle which is perfect for messengers.
The messenger is made from a plastic joining strip, used to join
laminated plywood together for bookselves, walls and ceilings. Very very cheap.
The strip is cut square and the thin strip of plastic used to close the top and
just the back part messenger, forming two square holes for the coat hanger wire.
In the prototype the body is about 36 cm long.
The sail is made from coat hanger wire, which after inserting
into the hinge (see below) is joined into a square by a bit of plastic tubing.
The sail itself is just kitchen tidy bag plastic decorated with permanent marker
pens (since faded). Ripstop or other fabric would be just as good. In the
prototype the sails are about 20 cm square.
The hinge for the sail was made by winding coat hanger wire, around a screw driver. This is done twice so the loops hug the width of the messenger body. the rest of the wire is then cut off. Two of these are made and taped to the plastic joining strip.
Perhaps a small ascii art will help explain this better...

Note that the sail frame is very loose in the hinge and thus is free to fold back easily by the wind.
The release rod is also coat hanger wire which was straightened
and then bent almost double. In the picture the wire is also kinked to allow me
to add a rubber band to pull the `release hook' close. I have found this is not
required. the messenger receives a good jolt when it hits the cork and this is
enough to overcome any friction on this wire.
In the photo is a picture of the release `hook' (upside down).
The plastic body was cut back to allow access to the wire just before the end.
When fully closed, the end is just inside the body of the messenger. Also in the
picture is a small ring (fiberglass washer from hardware store) with the lines
which hold the sail out into the wind.
To complete the messenger (do this last!) the other end of the
release wire is bent up into a open loop which can slide along the kite line. A
second such loop is taped to the outside of the body at the rear. Some
messengers (such as Dorf's Ferry) use two loops for the messenger to slide on,
which are separate to the release rod (wire).
That is it. Enjoy. Let me know how you go.
Sorry, no one has yet responded to this plan, or their experiences with Anthony's messenger. If do you build one, please mail me your experiences for inclusion here.
Thanks to all who have built this messenger and responded -- Anthony Thyssen.
