Module-Air Build Instructions
The Module-Air is a 33 ft. span, 14.5 pound flying wing. It is the 3rd in the “Go Big at Flite Fest” series. The idea is to provide a set of reference designs that can be built using locally sourced and inexpensive materials and flown at Flite Fest. These designs either break down for transport, or can be quickly assembled and discarded when the event is over. They are all 8 ft. span or larger and serve to demonstrate a set of build techniques that can be used to create large and inexpensive aircraft of any design.
The Module-Air is ideally suited to be a “team build” at the event. With suitable preparations it can be built in just a few hours. The disposable materials, primarily the Styrofoam insulation and pine trim molding, can be purchased locally for under $100. The various radio gear, batteries, servos, and flight controllers are all relatively inexpensive and reusable for other projects.
The build is not difficult but a general understanding of structures and RC techniques is assumed. Due to the use of a flight controller an intermediate or advanced builder should be part of the team. Due to the physical size and limited wind range an intermediate to advanced RC pilot is required.
It is possible to build the Module-Air at home and transport it to the event. With some care in packaging to prevent damage, the Module-Air can be broken down to a space about 97” x 30” x 9”. Assembly and disassembly time is only about 10 minutes.
