All Helix kits are constructed from the highest quality Basswood sheets, Poplar dowels and LOC Precision tubing. Their simple and robust construction means they will continue to fly long after other rockets have been retired. Launch preparation is super simple, just insert the motor and launch! These rockets fly very well even in windy conditions and always land close to the pad. The Double Helix kits use two motors for a unique and exciting, high performance, cluster flight.
Each kit comes with all materials need except glue. They can be built in a single evening using ordinary craft tools and supplies. This kit is recommended for experienced modelers who will appreciate it unusual construction techniques and flight characteristics. The Helix requires 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.
Plans for DIY Monocopter Launch Pad
The launch pad for monocopter should be sturdy and fixed firmly to the ground. Never attempt to launch the Helix from a standard launch pad with a long launch rod. A suitable launch pad can be constructed from the following materials:
- 4 - 2x4s, three, 18 inches long and one, 36 iinches long. The lengths need not be exact.
- 1 - 4 inch long, ¼-20 carriage bolt annd 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 the bottom of the short one with two
wood
screws. Attach the two remaining short 2x4s to the opposite ends of
the bottom of the first short 2x4 with two wood screws each.
Thread the two
remaining 1/4-20 nuts on the bolt and use them to adjust the height of
the rocket above the pad.
