Page 4: Tail Feathers
Use a straight edge to align elevator halves with bass wood joiner and bond with a high quality medium weight CA glue (Mercury 100XF works brilliantly here). © 2007 Stevens AeroModel. Page 9 of 35... - Page 5 Locate the 1/8” lite plywood former F1 – place on your work table with the scribed part number facing down. Install four 4-40 blind nuts and retain with medium CA glue (careful here – you do not want glue within the threaded portion of the blind nut). © 2007 Stevens AeroModel. Page 10 of 35...
- Page 6 (as instructed, you haven’t glued the crutch right?). With the test fit successful, tack glue each of the crutch parts together. Finally, tack glue both 1/8” balsa fuselage sides to the crutch at tab and notch locations as illustrated below. © 2007 Stevens AeroModel. Page 11 of 35...
- Page 7 10. Assemble former F8 from a laminate of 3/32” balsa and 1/32” plywood. Locate the 3/32” balsa part F8a and the 1/32” ply part F8b and, while carefully matching sides glue together to create a very strong F8 former! © 2007 Stevens AeroModel. Page 12 of 35...
- Page 8 13. Locate previously assembled 1/8” balsa former F11 (assembled in step 1) and install two (2) 4-40 blind nuts as illustrated below. Retain blind nuts with medium CA glue. Do not allow glue contact with the threaded portion of the blind nut. © 2007 Stevens AeroModel. Page 13 of 35...
- Page 9 PUSHRODS DESCRIBED IN STEPS 23 and 24 Now move aft within the fuselage, and install 1/32” plywood servo pocket supports SR3 to each side of the assembly (within the fuselage), as illustrated in the second photo below. *** © 2007 Stevens AeroModel. Page 14 of 35...
- Page 10 CA glue making certain that all parts are securely bonded. Hold you fuselage flat against your building surface while bonding to ensure that it remains straight. © 2007 Stevens AeroModel. Page 15 of 35...
- Page 11 Once the glue has dried you can pop the battery hatch on to the fuselage assembly in preparation for final sanding. © 2007 Stevens AeroModel. Page 16 of 35...
- Page 12 F5, F4, and F3. Tubing should extend 1/8” forward of F3 with excess length left at aft end of fuselage. Glue the push rod tubes in position using medium CA glue (do not allow glue to get within the tubing). © 2007 Stevens AeroModel. Page 17 of 35...
- Page 13 25. Final sand your fuselage using a sanding block and 400 grit paper. Slightly radius the edges of the fuselage and remove any exposed laser burn marks. DO NOT sand/modify the shape of the wing saddle. © 2007 Stevens AeroModel. Page 18 of 35...
- Page 14 Each component precisely interlocks using the interlocking I-beam construction method developed by Stevens AeroModel. Throughout construction, we suggest dry-fitting all components, and using minimal amounts of glue at tab and notch locations only to hold parts together. By dry fitting the wing, each successive component will assist with pulling the wing square and straight.
- Page 15 Use the plan sheet as a guide for rib location. While not required, you may tack glue the wing ribs to S1 at as long as you do so only where the rib meets the notches in the lower spar cap. © 2007 Stevens AeroModel. Page 20 of 35...
- Page 16 For this setup you’ll need to locate and install the following parts 1/32” ply SR65a and 1/8” balsa SR65b servo pockets spanning the S1 spar web and rib R2 and spanning the S1 spar web and rib R4. *** © 2007 Stevens AeroModel. Page 21 of 35...
- Page 17 With the trailing edge properly fit, tack glue the part to the assembly where it interlocks with each rib. © 2007 Stevens AeroModel. Page 22 of 35...
- Page 18 11. Install 3/16” balsa LE rib doublers marked “LE2” to the left and right inside surface of ribs R1. See photos below. © 2007 Stevens AeroModel. Page 23 of 35...
- Page 19 13. Install the leading edge center section 3/16” balsa parts marked “LE1”. Both of these parts can be found in the center of the 3/16” balsa aileron parts sheet SHAFT25E 07/21 and are glued one on top of the other at the wing center section as illustrated below.
- Page 20 16. Bond the 1/8” balsa W7 leading edge re-enforcements to the notches in rib R1. W7 should make full contact and be centered to the 1/4” balsa wing leading edge stock as illustrated below. © 2007 Stevens AeroModel. Page 25 of 35...
- Page 21 Thus beyond pre-cutting provisions for this option a bolt on wing is neither recommended nor supported by Stevens AeroModel. *** 20. DO NOT OVERLOOK THIS STEP YOU MUST FINAL GLUE ALL WING ASSEMBLY PARTS. For the most part we have been utilizing thin CA glue to hold parts in position while we complete the wing assembly.
- Page 22 (120-200) will suffice. 22. Run your sanding block across all exterior wing surfaces to remove the laser burn in preparation for covering. Do not significantly modify the shape of the airfoil as you sand. © 2007 Stevens AeroModel. Page 27 of 35...
- Page 23 Control horns DUB936 and Auxiliary BEC device to support the additional servo load. We are simply illustrating where we have accommodated this requested feature as running split ailerons is an advanced option for experienced modelers and is beyond the scope of this manual. *** © 2007 Stevens AeroModel.

- Page 24 1/4” dowel. Add more loops or increase rubber band gauge to reduce shock absorption of landing gear assembly. © 2007 Stevens AeroModel. Page 29 of 35...
- Page 25 Once the glue has cured use your pliers to bend the tail skid so that it extends straight out of plywood tail skid bracket. Now bend down as illustrated on plan sheet. Finish skid by rolling the end of the skid wire up as illustrated on the plan sheet. © 2007 Stevens AeroModel. Page 30 of 35...
- Page 26 Locate the provided ½” 4-40 bolts. The bolts will pass through the tail skid, then through the horizontal stabilizer and secure into the blind nuts that were installed within the fuselage at F11 as previously described in this text. © 2007 Stevens AeroModel. Page 31 of 35...
- Page 27 Du-Bro Micro2 EZ-Links (DUB920). In the photo series below covering and hinges have been omitted for clarity only as this step anticipates that your surfaces are covered and hinged. © 2007 Stevens AeroModel. Page 32 of 35...
- Page 28 DO NOT cross the rubber bands, use bands of greater size / thickness, or exceed six (6) rubber bands (three per side) as this will prevent the wing from cleanly departing the fuselage in the event of a crash. © 2007 Stevens AeroModel. Page 33 of 35...
- Page 29 Roll model inverted. Slight downward pressure on elevator should be required to maintain inverted flight. If significant amounts of elevator correction are required to maintain inverted flight, revisit CG setup and aileron setup as described in this text. © 2007 Stevens AeroModel. Page 34 of 35...
