This little guy was modeled after Sassy's Rudder Rail (see: http://www.spadtothebone.com/SPAD/SRR/).

Specifications:

Wing span: 48" (4 feet)
Weight:
Channels: Rudder, Elevator
 

Building Materials:

bullet48" of U-Channel 3/4" aluminum
bulletOne 2' x 4' sheet of 2-mil Coroplast for wing with flutes running in the 2' direction.
(online supplier: http://www.harborsales.net/fullsheetlookup.cfm?categoryID=6&subcategoryID=12)
bullet4-mil Coroplast for tailfeathers
bullet2 Yardsticks for wing spar
bulletSelf-tapping screws (5/8")
bulletHot Glue (and hot glue gun with HOT setting)
bullet1/4" wooden dowels (for securing wing to fuse and for pushrods)
bulletBicycle spoke wire or equivalent (for pushrod ends).  Surveyors flags also work (they come with 1/16" wire that makes great pushrods).  Also, insulation tie down rods (3/32") work well.
bulletZip Ties for securing servos to fuse and pushrod ends to dowel
bulletRectangle block of EPP or Styrofoam for nose cone.  4" x 2 3/8" x 2 3/8"
bulletR/C Radio with receiver, on-board receiver battery, and 2 servos (standard size)

Complexity:

The U-Can-2 builds quickly, usually under 4 hours.  It flies slow to medium fast, yet is light enough for low lift days 5-10 mph.  It is designed to be an easy to build yet durable trainer for those new to the sport of R/C soaring.

Since it has only 2 channels, it is very low complexity in terms of radio installation.  Simply install the Elevator and Rudder servos, attach them to the the Elevator and Rudder respectively, install the battery into the EPP "Pod/Nose cone", rubber band or Velcro the receiver to the fuse and route the Antenna.  Done.
