18mm Dragonfly Monocopter
Dragonfly set to take off
These monocopter kits take model rocketry in a new direction, a tight, skyward spiral. They leap off the launch pad with a loud growl and tears into the sky leaving a unique, corkscrew smoke trail. At apogee they hover for several seconds then flutters gently to the ground. Unlike conventional rockets, they fly better on windy days. They will land close to the launch pad under all flying conditions and are nearly impossible to get stuck in trees or power lines.
Each kit is constructed from the highest quality Basswood sheets, Poplar dowels and LOC Precision tubing. Their simple and robust construction mean they will continue to fly long after other rockets have been retired.
Each kit comes with all materials except glue. A kit can be built in a single evening using ordinary craft tools and supplies. These kits are recommended for experienced modelers who will appreciate their unusual construction techniques and flight characteristics. These monocopters require a strong launch pad with a short 1/4" rod. Instructions for building a suitable pad out of readily available materials are included with the kit and also shown below.

Monocopter Launch Pad
A monocopter launch pad should be sturdy and fixed firmly to the ground. Never try to launch a monocopter from a long rod on a standard launch pad. A suitable launch pad can be constructed from the following materials:
- 4 - 2x4s, three, 18 inches long and 1 - 2x4, 36 inches long. The lengths need not be exact.
- 1 - 3 inch long, ¼-20 carriage bolt and 3 nuts
- 6 -3 inch long wood screws.
Drill
a 1/4” hole in the middle of one of the short 2x4s. Insert the
carriage bolt into the hole and secure it tightly with one of the nuts.
Attach
the long 2x4, perpendicular to bottom of the short one with two wood
screws. Attach the two remaining short 2x4s to the opposite ends of
bottom of the first short 2x4 with two wood screws each. Thread
the two remaining nuts on the bolt and use them to adjust the height of
the rocket above the pad.
