The FT Versa Wing is a flying wing built from Dollar Tree foam board, which is designed to be built quickly and cheaply. You can order a laser-cut kit from the Flite Test store for about $30, or laser cut your own using the Lasersaur at the space for about $5 in materials and laser time.

Hardware Options

Pusher vs Tractor

The versa can use a tractor setup by using the standard FT Power Pod, or a pusher by using the FT Elements motor mount.

Motor Mount

For pusher configuration, the motor mount can either be laser-cut out of 3/32" plywood, or 3d printed out of ABS.

Control Horns

The control horns can be either laser cut from 3/32" plywood, or 3D printed out of ABS.

Materials

To build a versa wing, you will need the following things:

  • 3 sheets of Dollar Tree foam board (2 if you are building a pusher version without the blunt nose section)
  • Hot glue gun
  • Hobby knife or razor blade
  • 2 popsicle sticks
  • 3/32" aircraft plywood (not required if 3d printing hardware)
  • Control rods

Laser and 3D Printer Files

Here are all of the files required to build your very own Versa Wing. These links will be kept up-to-date with any bugfixes.

Pusher Version

This version has been slightly modified from the original FT plans. The notches for the power pod have been removed, and hatches have been added to the wing underside to allow access to the servos once built.

Tractor Version

This version requires the FT Power Pod.

Blunt Nose Center Section

Power Pod

This is only required if you are building the tractor version. However, it can also be used with other FT swappable aircraft designs.

Control Horns

FPV Version

This is a modified blunt nose version designed for pusher use only. The winglets have been enlarged to increase yaw stability, and all power pod holes and unused cuts have been removed. The servos mount vertically on the tabs, instead of inside the wing as well. The hatch area has been changed to one large hatch, instead of two small ones. The DMS logo and some text has also been added (purple color). These can be etched directly onto the foam at around 6 to 7% power. If you don't want the logo and text, simply ignore the purple lines when laser cutting.

Laser Cutting

The Lasersaur Laser Cutter is used for laser-cutting the versa. It seems to give the best results, I had problems with the full spectrum laser cutting through the foam even at the lowest power settings.

These power settings work well on the Lasersaur with Dollar Tree foam board:

Color Action Feed Rate Power Level Passes
Black Cut 1500 25% 1
Red Score 1500 13% 1
Blue Etch 1500 7% 1

The following settings work well on the Lasersaur with 3/32" plywood:

Color Action Feed Rate Power Level Passes
Black Cut 1500  ?  ?

3D Printing

ABS should be used for strength, and parts should be printed at high-density.

Assembly

Flite Test has created great videos showing the full build process in detail:

Notes

In pusher configuration, both the standard and blunt nose versa will probably need nose-weight added in order to balance out. This makes it useful for carrying FPV gear, and you should try to mount the gear as far forward as possible. For the blunt nose version, you can hot glue AA size batteries in the nose as ballast.
