Quote: "Smart-e is compact, simple and rugged. It is maneuverable, stable and predictable enough to fly in a cul-de-sac. It is so easy to do basic aileron and elevator aerobatics in the park, even in a breeze, that Smart-e will make you look good. Smart-e is the model you grab to go flying on the spur of the moment because you know it is easy, low stress fun.

The fuselage is a sandwich of 1/2 inch white Styrofoam and 1/16 balsa making it quick to build, light and very strong. The receiver and ESC attach to the 'semi-profile' fuselage side with Velcro and the elevator servo and battery are imbedded in the fuselage.

Components are pretty standard, an Emax 2822 outrunner motor, 12A ESC, a 3s 610 Li Po, micro receiver and three micro servos. For the sake of simplicity and lightness, the Smart-e presented here has a fixed rudder.

Build the wing first. Cut spars, trailing edge, ailerons, wingtips, servo mounts and gussets from 3/32 balsa. Using a template made from a photo copy glued to cereal box cardboard or 1/32 ply, cut ribs out of 3/32 balsa, slightly oversize. Stack the ribs and pin them together, sand to size and notch for leading and trailing edges and spars.

After the ribs are made, cut the 1/16 vertical grain balsa sheer webs to match the space between top and bottom spar, as measured on the ribs you just made, and cut them to length. Trim 2 sheer webs at the dihedral angle.

Pin the trailing edge to wax paper covered plans, put bottom spar in place and glue the first rib and sheer web in place, canted at the dihedral angle. Glue the second rib in place, then the sheer web, then third rib and sheer web and so forth to the tip rib.

Then add top spar and turbulator spar. Glue the 1/8 hardwood dowel leading edge in place. If it has a slight bow, place the bow forward, (not up or down), to minimize warps. Sand a bevel on the straight edge of the wing tip, glue in place with gussets. Glue all other gussets in place.

Note grain direction of the servo mounts on the plan. Glue the shorter servo mount to the side of the rib, butted against the rear edge of the bottom spar. Then glue the longer, servo mount on top of the first. It butts against the sheer web.

When the left wing panel is complete, remove it from the plans and build a right wing panel. Don't forget to put the wingtip, servo mount and gussets in the correct location for the right wing! Add the servo wire exit gusset to the right wing, between the center rib and the rear edge of the spar..."

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
