Cutlass Supreme (oz14741)

About this Plan

Cutlass Supreme. Radio control pattern plane, for .60 power.

The Cutlass (oz12836) design first appeared in MAN, Oct 1970 (with a foam wing). This here is the Cutlass as kitted by Joy Products (with built-up balsa wing).

Planfile includes full build instructions.

Quote: "CUTLASS SUPREME BUILDING INSTRUCTIONS. FUSELAGE: Firewall location may have to be altered to suit your engine. Bottom corners of the fuselage can best be contoured after two lower filler blocks are glued in place.

Build crutch from 1/4 sq balsa over top view. Glue fuselage doublers to body sides, being careful to make one right and one left. Notch crutch to suit doublers. Pin body sides to crutch (upside down over top view). Fit all bulkheads. Remove body sides, apply glue and pin body sides in place. Glue all bulkheads in place, remove fuselage from plan when dry. Cut out cockpit opening if desired and glue block place. Glue all deck formers in place, apply 3/32 balsa deck sheeting (see note on plan). Fit engine, mount and nosegear. Glue two lower blocks in place. Glue 1/8 plywood nosering in place, fit and glue canopy in place. Fin and dorsal are glued in place after stab is installed. Bottom of fuselage is contoured after wing is complete and bolted in place with pan installed.

STABILIZER: Pin 1/4 sq balsa to plan as shown. This raises ribs off drawing and keeps stab flat. Pin LE and TE in place. Trim ribs to fit and glue in place. Add 3/16 sq spar and top 1/16 sheeting, let dry overnight, remove from plan and apply bottom 1/ 16 sheeting block up, level and let dry. Add tips and sand. Glue stab to fuselage at this time. Be sure to block up stab level and square. Add fin and dorsal. Trim aft blocks and glue in place. Add rudder and tailskid.

WING: Note that fiberglass reinforcement is used to join the two wing halves. Do not eliminate this as there are no dihedral braces in wing. It is strongly recommended that a wing jig be used, if a wing jig is not used extreme care must be taken to build wing panels without warps.

Wing construction is very basic so only possible pitfalls will be pointed out. Glue tips in place and shape after wing is sheeted. Gear blocks are glued level with sheeting and capstrips. Be sure to oil or grease aileron torque rod before installing and be careful to keep glue out of brass tube bearings. Before gluing bottom center section sheeting in place, drill holes for wing dowels through LE and 1/16 plywood, set wing in fuselage.

Run drill bit by hand through wing to mark bhd, remove wing and glue dowels and bottom center section sheeting in place. Drill holes through bhd, set wing in place. Line up square and drill aft bolt holes. Bolt wing in place and fit bottom pan. Remove wing and install radio temporarily. Fit push-rods, glue 1/2 in triangle and bottom sheeting in place. Bolt wing in place and contour bottom corners of fuselage.

The complete story of the CUTLASS was published in Model Airplane News, in October 1970."
