Remval f material shuld nt be required. If yu feel that yu have a pr cnnectin, check first t see that the part is nt upside dwn. Reference each piece against the plan sheet. Making slid glue jints: Hld parts tgether n tp f plan sheet using mderate pressure t fit parts. Wick Thin CA int jint. There is n need t pin parts t wrk table as all pieces interlck and self - jig Stevens AerMdel. Page 5 f 34

5 Tail Feathers General Cnstructin Ntes: This kit features ur prprietary Trus-Lc system as such typical stick type cnstructin has been replaced by precisely cut stick cmpnents that are keyed t fit in nly ne directin. The knuckles f the truss are identified with an alpha-numeric use this t match adjining truss cmpnents A t A and B t B etc. If a part des nt fit prperly chances are very gd that yu have the wrng part r the part is in backwards. Under n circumstances shuld yu need t fill significant gaps r re shape the parts. 1. All f the parts t create the tail feathers are lcated n the 3/32 balsa sheet SHAFTMIC-04/06. Parts are gruped n the sheet by the assembly t which they belng using a simple scribe line that surrunds the parts grup. Wrk nly with ne grup f parts at a time and remve these frm the sheet with a sharp #11 hbby blade. Assemble the parts n tp f yur plan sheet using the drawings n the sheet t reference rientatin. Frame up all tail feather cmpnents as illustrated belw. A A A A A A B B B B B B B B 2. Jin the elevatr halves. Prepare the surfaces f the elevatr and 3/32 in. basswd jiner by lightly sanding the laser burn frm the parts. Assemble the parts n tp f yur plan sheet using the drawings n the sheet t reference rientatin. Use a straight edge t assist with alignment f the leading edge f the elevatr assembly Stevens AerMdel. Page 6 f 34

6 Fuselage General Cnstructin Ntes: This fuselage utilizes an imprved tab and ntch cnstructin methd pineered by Stevens AerMdel. Each cmpnent precisely interlcks using unique tab and ntch sizes t allw the parts t nly fit in ne directin. Where parts rientatin can be reversed r inverted parts are scribed with a reference such as tp r frnt fr prper rientatin. Thrughut cnstructin we suggest dry-fitting all cmpnents, and using minimal amunts f glue at tab and ntch lcatins nly t hld parts tgether. By dry fitting the fuselage, each successive cmpnent will assist with pulling the assembly square and straight. 1. Assembly f the fuselage crutch begins. USE NO GLUE TO BOND THE PARTS UNTIL INSTRUCTED. Lcate the plywd frmer parts F0 and F2. Nte: Bth F0 and F2 are scribed TOP t indicate prper rientatin. Ensure TOP faces up and frward (twards mtr). Place F2 thrugh the large lightening hle in F0. Align the ntches in F2 with the inside rails f F0, then rtate F2 int the receiving ntches f F0. Hint: This fit is snug s gently cax the part int psitin wrking ne side, then the ther be mindful f hw much frce yu use s that yu d nt break the part. See illustratin belw. 2. Lcate the 1/32 in. plywd frmers F1 and F3 and key these t the fuselage crutch assembly as illustrated belw. Again, these frmers have been identified with the scribing f TOP n each part t signal the tp and frward rientatin f the cmpnent Stevens AerMdel. Page 7 f 34

7 3. Verify that upn cmpletin f step 3, yur assembled fuselage crutch lks identical t the first pht belw. Next, key the 1/32 in. plywd G1 landing gear supprts t bth sides f the fuselage crutch, as illustrated in the secnd pht belw. 4. Test fit the cmpleted fuselage crutch t ne f the 1/16 in. balsa FS fuselage sides. Any failure t fllw the prper tp-side part rientatin will be revealed here. If the tabs in yur fuselage crutch d nt align with the ntches in the fuselage side yu will need t re-visit the crutch assembly and pay careful attentin t the tpside part rientatin (as instructed, yu haven t glued the crutch right?). With the test fit successful, tack glue each f the crutch parts tgether. Finally, tack glue bth 1/16 in. balsa fuselage sides t the crutch at tab and ntch lcatins as illustrated belw. 5. F1 will bear a cnsiderable lad frm in-flight stresses frm the mtr and prpeller. With the fuselage sides jined t the crutch, and access t the F1 firewall still un-restricted, nw is the time t thrughly bnd frmer F1 t the frward prtin f the crutch and the fuselage sides. Wick liberal amunts f thin CA glue alng the jints where F1 tuches the fuselage assembly. Once the thin CA glue has cured, build up a fillet f medium CA glue alng the same jints. 6. Glue the 1/20 inch fuselage side wall dublers labeled F10a t bth inside surfaces f the fuselage side wall just frward f F2 as illustrated belw Stevens AerMdel. Page 8 f 34

8 7. Key 1/16 in. balsa frmer F7 t tp-side f fuselage assembly. Invert fuselage and key frmer F8 t underside f fuselage assembly. Square fuselage and parts t yur flat wrk surface and prceed t glue frmers F7 and F8 in place. See illustratin belw. 8. Key the 1/16 in. plywd G2 landing gear re-enfrcement strap t the ntches prvided in the underside f the fuselage, and glue. Wick liberal amunts f CA glue alng inside jints f G2 t G1 and fuselage sides. 9. Lcate the 1/32 ply part marked F00 and using a sanding blck dress the edges f the part dwn t facilitate it s fit t the central fuselage crutch FO. Use the plan set and these phts t reference psitin. Nte that F00 is marked TOP make certain t rient the part prperly within the fuselage assembly. D nt frce the fit. If the fit is snug cntinue t lightly dress the edges f the part dwn Stevens AerMdel. Page 9 f 34

9 10. **OPTIONAL STEP if yu wish t make the Hrizntal Stabilizer f the SHAFT micr remvable purchase the ptinal DuBr RC blind nuts DUB309. Lcate 3/32 in. balsa frmer F11 and install tw (2) 2-56 blind nuts as illustrated belw. Retain blind nuts with a drp f thin CA glue. D nt allw glue cntact with the threaded prtin f the blind nut. 11. Befre applying glue, lcate the 1/32 in. plywd frmer F6, and key it t balsa frmer F11, and fuselage sides, as illustrated belw. Square fuselage t building bard and tack glue parts int psitin at tab and ntch lcatins. VERY IMPORTANT: The rim and spike prtin f the blind nut shuld be lcated within the fuselage bdy (n the same side as the large lightening hle in frmer F6) s that the threaded prtin f the blind nut is expsed t the underside f the fuselage. Pay clse attentin t the illustratins abve and belw s that yu dn t inadvertently install part F11 upside dwn. Nte: Pht shws the fuselage upside dwn. 12. Bnd 1/20 in. balsa frmer F12 t fuselage as illustrated. Next, key 1/20 in. balsa part F13 t underside f fuselage atp F12, and spanning fuselage sides, and frmer F3. Make certain that F13 fits flush with fuselage sides, and then tack glue frmer int psitin at all tab and ntch lcatins Stevens AerMdel. Page 10 f 34

10 13. Befre we seal up the aft prtin f the fuselage, we have sme imprtant business t attend t. First, install the 1/20 in. balsa crss-grain dublers F10b within the fuselage assembly, flush with frmer F3 and F13, as illustrated in the first pht. 14. Cmplete the mid sectin f the aft fuselage assembly by first installing the 1/32 in. plywd frmers F4 and F5 as illustrated belw. Next, key the 1/16 balsa frmer F9 t the tp f the fuselage assembly spanning frmers F3, F4, F5, F6 and fuselage sides, as illustrated belw. 15. Fr the mst part we have been utilizing thin CA glue t hld parts in psitin while we cmplete the fuselage assembly. At this pint it s time t finalize the fuselage by re-visiting every surface t surface jint with thin CA glue making certain that all parts are securely bnded. Hld yu fuselage flat against yur building surface while bnding t ensure that it remains straight Stevens AerMdel. Page 11 f 34

11 16. Battery hatch assembly: Lcate the 1/20 in. balsa parts H2a and H2b and assemble tgether at dve-tail jints t create part H2. Next lcate part H1 and align atp H2 using the scribe marks n H2 and vent hle in parts t assist with prper centering f H1. While hlding the hatch assembly flat n yur wrk surface prceed t wick liberal amunts f thin CA between parts. Finally, glue ne f the 3/16 diameter ne. magnets int the 3/16 diameter hle, as illustrated in the third pht. 17. Install battery hatch catch within fuselage assembly. Lcate the 1/32 in. plywd part H3 and 1/16 in. balsa part H4 and install these t the fuselage using the plan sheet and illustratins belw t guide yur wrk Stevens AerMdel. Page 12 f 34

12 18. Cmplete assembly by installing the secnd ne. magnet within the assembled catch. VERY IMPORTANT: Magnets are plarized. They will attract with great frce and will likewise repel each ther with great frce if ne f the ples is reversed. Check t see that magnets stick t each ther. Tip: Mark cntacting faces with permanent marker. Install the secnd magnet with the marked side facing ut. Duble check that when the hatch is installed t the fuselage it will be attracted t the catch. Glue the magnet t the catch assembly by wicking thin ca glue arund the magnet. Once the glue has dried yu can pp the battery hatch n t the fuselage assembly in preparatin fr final sanding. 19. Final sand yur fuselage using a sanding blck and 400 grit paper. Slightly radius the edges f the fuselage and remve any expsed laser burn marks. DO NOT sand/mdify the shape f the wing saddle Stevens AerMdel. Page 13 f 34

13 Push-Rd Husing 1. Prir t cvering the fuselage yu will need t install the push-rd husing fr bth elevatr and rudder. Cut the prvided 18 in. length f nyln pushrd husing int tw equal (9 in.) sectins. Thread each f these thrugh the fuselage beginning with the hles in frm F3 then F4, and F5, crss the husing aft f F5 then rute thrugh F6 and ut each side f the fuselage thrugh the pre-cut push-rd exit hle. Leave 1/8 f extra tubing frward f frmer F3. Glue the husing int psitin at each pint f cntact with the fuselage. Using a sharp razr blade trim the verhang flush with the fuselage sides Stevens AerMdel. Page 14 f 34

14 Wing General Cnstructin Ntes: This wing is f typical I-Beam cnstructin with additinal trsinal strength derived frm the trussed sub ribs. Each cmpnent precisely interlcks using the interlcking I-beam cnstructin methd develped by Stevens AerMdel. Thrughut cnstructin, we suggest dry-fitting all cmpnents, and using minimal amunts f glue at tab and ntch lcatins nly t hld parts tgether. By dry fitting the wing, each successive cmpnent will assist with pulling the wing square and straight. It is nt required t pin the wing t yur building surface. In-fact, mst f yur building will be dne abve the bard. Yu will, hwever, require a flat surface t set the wing n tp f fr final gluing f the assembly. 1. A big first step! Yu ll key tgether 3 majr cmpnents in this first step t frm the wing center sectin. First, lcate the 1/32 in. plywd spar dubler S1b and center this t the 1/6 in. balsa S1a spar web matching the parts at the ntches fr ribs R1. Nw use the 3/32 in. balsa ribs R1 t assist with lcatin f the spar dubler and spar web. Finally, lay in the lwer spar cap S2 using the tab and ntch pints fr lcatin. Square the assembly n yur flat wrk table taking particular care t make certain that the ply dubler is square and prperly seated alng the lwer spar cap. Retain parts with a drp f thin CA glue at tab and ntch lcatins. VERY IMPORTANT: The plywd dubler S1b must face frward tward the wing leading edge. Set the secnd S2 spar cap aside as this will nt be jined t the assembly until much later. See illustratin belw fr cmpleted assembly. 2. Fill ut the remainder f the wing by installing 1/16 balsa wing ribs R2, R3, R4, and 1/8 balsa rib R5 t the S1 spar web. Use the plan sheet as a guide fr rib lcatin. While nt required, yu may tack glue the wing ribs t S1 at as lng as yu d s nly where the rib meets the ntches in the lwer spar cap Stevens AerMdel. Page 15 f 34

15 3. Install the 1/32in. plywd SR1a serv pcket t assembly by aligning tabs f SR1a t ntches in rib R2 and S1a spar web. G ahead and bnd SR1a in place making certain it is firmly seated against spar web, spar cap strip and rib. Nw bnd the 1/16 balsa part SR1b n tp f the plywd SR1 serv pcket and flush with the edge f the S2 spar cap and rib R2. 4. Lcate the 1/6 in. balsa part W6 and bnd t the wing center sectin using the ntches in ribs R1 t align with the tabs in the W6 part. 5. Key the 3/32 in. balsa T1a trailing edge t wing assembly. The ntched trailing edge shuld seat flush with the bttm and trailing edge f the wing assembly ribs. With the trailing edge prperly fit, tack glue the part t the assembly where it interlcks with each rib Stevens AerMdel. Page 16 f 34

16 6. Install the 1/20 in. balsa W3 wing truss cmpnents. The trailing edge f W3 shuld be cmpletely received within the ntches at the wing trailing edge, and fit with full cntact against the spar and wing ribs at the leading edge f W3. Dry fit all W3 parts t pull the wing assembly square. Next, key the 3/32 in. balsa wing tips W5 t the assembly and tack int psitin with a drp f CA glue where it meets the uter wing rib and trailing edge. Lay the wing flat n tp f yur building bard. Then prceed t tack glue the W3 truss parts at the trailing edge and where they cntact the S1a spar web and S2 spar cap. 7. 1/20 in. balsa sub ribs R1a, R2a, R3a, and R4a and key these t the S1 spar web as illustrated belw. Inspect the fit t make certain that the sub ribs seat flush with the web, then tack glue the sub ribs frm the back side f the web at the tab and ntch jint. 8. Install the 3/32 in. leading edge center sectin rib dublers marked LE2. LE2 shuld be psitined n the inside surface f rib R1 flush with the wing spar and matched t the edges f R1. Once satisfied with the fit f the part glue int psitin Stevens AerMdel. Page 17 f 34

17 9. Lcate the 1/16 in. balsa W1 turbulatr (W2 is smaller than W1 and lacks ntches). W1 is ntched n ne side and shuld be installed t the frward mst turbulatr ntch spanning all ribs. Next install tw (2) W2 turbulatrs in remaining slts atp wing ribs. See illustratins belw. VERY IMPORTANT: The tp surface f turbulatrs W1 and W2 will fit flush with the tp surface f ribs R1 and R5. Alng all mid-span ribs R2 thrugh R4 turbulatrs W1 and W2 will seat prud f the tp rib surface by 1/20 in. Lcate a scrap piece f 1/20 in. balsa and use it t reference the prper installatin height f W1 and W Install the leading edge center sectin. These 3/32 in. balsa parts are marked LE1 and are designed t fit, ne n tp f the ther, within the ntch at the leading edge f LE2 spanning the center sectin as illustrated belw Stevens AerMdel. Page 18 f 34

18 11. Install the pre-cut 1/8 in. square leading edge stck. Seat the leading edge stck s that it fits with full cntact within the leading edge f the wing ribs and bnd with thin CA glue. 12. Lcate the secnd 1/16 in. balsa S2 spar cap strip and install t tp side f spar web as illustrated belw. 13. Bnd the 1/16 in. balsa W7 leading edge re-enfrcements t the ntches in rib R1. W7 shuld make full cntact and be centered t the 1/8 in. balsa wing leading edge stck as illustrated belw Stevens AerMdel. Page 19 f 34

19 14. Install the 1/32 in. plywd W4 trailing edge re-enfrcement within the ntch at the wing trailing edge center sectin. 15. Final glue all wing assembly parts. Fr the mst part we have been utilizing thin CA glue t hld parts in psitin while we cmplete the wing assembly. At this pint it s time t finalize the wing assembly by re-visiting every surface t surface jint with thin CA glue making certain that all parts are securely bnded. Hld yu wing flat against yur building surface while bnding t ensure that it remains straight. 16. Shape the leading edge. Grab yur 400 grit sanding blck and razr plane. Prceed t rugh the leading edge f the wing rund using yur razr plane then fllw up with a few swipes f 400 grit paper n yur sanding blck. Test fit the wing t fuselage ften thrugh this prcess. Just as the turbulatrs alng mid-span ribs sit prud by 1/20 in. s shuld yur wing leading edge. That is t say, yur wing leading edge shuld be sanded flush with the prfile f nly ribs R1 and R5, and remain prud f the mid-span ribs by 1/20 in. (see step 9 and use scrap 1/20 in. balsa as a guide). A razr plane makes shrt wrk f shaping cmpnents such as wing leading and trailing edges (we suggest the Master Airscrew MAS4100 razr plane). If yu d nt have the luxury f a $7 razr plane fr this prject a lng sanding blck r bar laded with mre aggressive grit paper ( ) will suffice. 17. Run yur sanding blck acrss all exterir wing surfaces t remve the laser burn in preparatin fr cvering. D nt significantly mdify the shape f the airfil as yu sand Stevens AerMdel. Page 20 f 34

20 Ailerns: 1. All f the parts t create the Ailerns are lcated n the 3/32 balsa sheet SHAFTMIC-05/06. Assemble tw (2) ailerns as illustrated belw frm 1/8 balsa parts A1, A2, A3, A4, and A5. Use the plan sheet t reference part lcatins. The 1/8 balsa sheet labeled SHAFT-04/12 cntains the skinny vertical stick A6, and the lng Ailern Diagnal sticks. A3 A1 a a a a A2 A4 b b b b Hard Pints 1. Use the plan sheet t reference the lcatin and sizing f bth 1/8 in. hardwd wing retentin dwels. Cut dwels t length and sand a chamfer r rund the edges f the dwels. With cnstant pressure, and a gentle twisting mtin, wrk the dwels thrugh the hles in the fuselage sides. Remve dwels and retain fr installatin AFTER the mdel has been cvered. Tip: Harden dwel hles with Thin CA. 2. The pht belw illustrates hw the landing gear is banded t each side f the 3/16 dwel hard pint. The methd fr landing gear attachment is as fllws: Start rubber band arund 3/16 dwel then wrap arund the tp lp f the landing gear and back arund tp f dwel repeat s that yu have a minimum f 4 wraps f rubber band arund the landing gear lp and dwel then place the end lp f the rubber band ver the 3/16 dwel. Add mre lps r increase rubber band gauge t reduce shck absrptin f landing gear assembly Stevens AerMdel. Page 21 f 34

21 Tail Skid 1. Use the prvided 1/32 in. music wire stck and cut/bend t shape as described n the plan sheet as described under the heading Tail Skid / Hrizntal Stab. Retaining Bracket. Next, gather the 1/32 in. plywd tail skid parts F14a, F14b, and F14c. With the required parts in hand, begin assembly by bnding F14b atp F14a. Finally, glue F14c n tp f F14b. 2. Once the glue has cured use yur pliers t bend the tail skid s that it extends straight ut f plywd tail skid bracket. Nw bend dwn as illustrated n plan sheet. Finish skid by rlling the end f the skid wire up as illustrated n the plan sheet Stevens AerMdel. Page 22 f 34

22 Final Assembly Ntes General infrmatin: Final assembly assumes that the builder has sme degree f experience finishing ARF style mdels and will nt be described in agnizing detail. Verify parts fit and hinge methd: Prir t cvering this mdel all cmpnents shuld be dry fit tgether, Pay clse attentin t the fit f the wing t the wing saddle in the fuselage and the fit f the vertical stabilizer t the fuselage assembly. Yu must als have prepared yur cntrl surfaces based upn the hinge scheme. By far the quickest methd fr hinging cntrl surfaces is using tape hinges. Tp hinged tape hinges are quick, prduce sme degree f differential thrw fr the ailerns, and d nt require gap sealing. The plan sheet suggests hw t sand the leading edge f the cntrl surfaces in preparatin fr the tape hinge methd. Cver the mdel: Cver all wing and fuselage cmpnents using yur favrite cvering. We recmmend using AerFILM Lite r AerFILM available frm StevensAer.Cm. AerFILM Lite will save abut z. in weight ver AerFILM r heavier cvering materials. As cvering techniques are beynd the scpe f this build manual we suggest visiting the AerFILM prduct page at ur web site ( and reading the AerFILM cvering guide. Where t remve cvering: When cvering yu shuld remve cvering frm the lightening hle in frmer F1 t allw cling airflw within the fuselage. Remve cvering frm the vent hle in the battery hatch t allw cling air t exit the fuselage and allw yu a finger hld fr installatin and remval f the hatch. While It is nt required t remve cvering frm the vertical stabilizer where it bnds t the fuselage we d suggest that yu remve cvering frm the adjining surfaces f bth the hrizntal stabilizer and the fuselage if n using the ptinal blt tgether tail. Hinge cntrl surfaces: Attach cntrl surfaces t the mdel using the tape hinge methd described n the plan set, r with CA hinges if yu prefer that ptin. Install hard pints fr wing and gear: Center the 1/8 in. dwels fr wing retentin t the fuselage and secure with CA glue. Center the 1/8 in. dwel fr landing gear retentin and secure t the fuselage with thin CA glue. Installatin f tail feathers: Key the vertical stabilizer and rudder t the fuselage. See that the tabs in the vertical stabilizer fit the ntches in the fuselage and secure with thin CA glue. Blt the elevatr assembly and tail skid in place as described previusly in this manual. Munt the wing: Retain wing t fuselage using fur (4) #16 rubber bands tw (2) n each side f the fuselage. Use fresh rubber bands prir t each flying sessin. D nt crss the rubber bands ver the wing as this will prevent the wing frm cleanly departing the fuselage in the event f a crash. **Optinal install 1/32 in. ply parts marked LE3 t slts in leading edge frmed by LE1 and LE2. Nte that cvering has been mitted frm this pht fr clarity. LE3, if installed, shuld be glued int psitin as illustrated after the wing has been sanded, leading edge shaped, and cvering applied Stevens AerMdel. Page 23 f 34

23 Radi and serv installatin: Install yur receiver and servs. We suggest fur (4) Blue Bird 303 r similar (Cirrus CS101) servs. Reference the plan sheet fr serv lcatins. With yur servs installed, fire up yur radi and center all servs. Mechanically center yur serv cntrl hrns s that they are perpendicular t the serv bdy. Install the prvided Du-Br EZ-Cnnectrs (DUB845) t the inner mst hle n all serv cntrl arms (yu can mve this munting psitin farther ut alng the serv cntrl hrn fr mre aggressive surface travel). Quality Du-Br Micr (DUB848) single pst cntrl hrns have been prvided in this kit. Install these n the same side f the cntrl surface that yur serv resides n. Cntrl hrns will install int the laser drilled hles in each part. Use the plan sheet as a guide t bend yur push/pull rds frm the included 1/32 in. wire stck. Install push/pull rds int the uter mst psitin n cntrl surface hrns using the prvided Du-Br Micr2 EZ-Links (DUB849). Cntrl surface adjustments: Adjust rudder parallel with vertical stabilizer and set psitin by tightening set screw in EZ- Cnnectr. Adjust elevatr parallel with hrizntal stabilizer and set psitin by tightening set screw in EZ-Cnnectr. VERY IMPORTANT: With the wing seated in fuselage adjust ailern parallel t angle f tp side f fuselage. Under n circumstances shuld the ailerns be centered flat with the bttm surface f the wing. If using a cmputer radi set cntrl surface thrws t thse recmmended in this manual. We suggest a starting pint f 30% exp t smth ut yur cntrl f the sticks. Adjust travel t the fllwing starting pint: Ailern +/- 10 degrees 30% exp Elevatr +/- 20 degrees 30% exp Rudder +/- 40 degrees 50% exp Mtr and prpeller munting: Munt the Hacker A10-12S using the radial munting hardware included with the mtr package. Secure the mtr t the firewall using fur (4) #2 x ¼ sheet metal screws. Prper dwn thrust is built int the firewall. Tw 1/32 in. plywd washers are prvided in this kit t shim the left side f the mtr (as viewed frm the cckpit) t achieve prper right thrust. Start by placing ne 1/32 ply washer under each f the tw left side mtr munt arms. Right thrust will vary with yur pwer system selectin but we have fund that with the recmmended Hacker A10-12S and 6x3 GWS HD prpeller ne 1/32 in. shim is typically enugh. Install yur balanced prpeller t the mtr. Never run a prpeller assuming it is in balance withut checking it first. Never run a prpeller that is knwn t be damaged, repaired, r ut f balance. Never run a mtr with a bent shaft. Inflight vibratin frm ut f rund and ut f balance cmpnents will cause pre-mature failure f airframe and electrical cmpnents. If yu are un-certain hw t balance a prpeller, seek advice frm an experienced hbbyist r yur lcal hbby retailer Stevens AerMdel. Page 24 f 34

24 Landing gear assembly: Use the prvided length f 1/16 in. wire, needle nse r rund nse pliers, and yur plan set (as a template) and bend wire t match shape indicated n plans. Next lcate the prvided fam wheels and,if necessary t allw wheels t spin freely n axle, ream the hubs f the included wheels using a 1/16 in. drill bit. Ream slwly and test ften by spinning the wheel t prevent wbble. Place wheels n the landing gear assembly and retain by frcing the plastic wheel retainers (ne n each side f wheel) ver the 1/16 in. axle. Retain landing gear t fuselage using tw (2) #16 rubber bands ne (1) n each side f the fuselage. Use fresh rubber bands prir t every flying sessin. Use the methd fr landing gear attachment as described previusly in this text. Battery installatin and Center f Gravity: Mve battery fre and aft within fuselage t adjust the mdels Center f Gravity (CG). We suggest lcating the CG f the mdel in the upright psitin s that the fuselage bttm is level with the hrizn when balancing the airframe by a finger tip psitined n the underside f each wing panel 2 in. aft f the wing leading edge. Lateral mdel balance: Place a rund head pin in the rudder assembly near the bttm f the rudder. With the rudder aligned parallel t the fuselage and vertical stabilizer supprt the mdel inverted with ne finger n pin head and the ther finger n the mtr shaft. With the mdel suspended in this fashin yur wing tips shuld balance level with the hrizn. If yur mdel des nt balance laterally, add an apprpriate amunt f weight t the high wing tip until mdel balances. Hint: I use adhesive graphics like cntrasting clr bars n the underside f my wing t balance the mdel and aid visibility. Warped structure: Check wing and tail surfaces ver carefully lking fr signs f twists r warps that will need t be remved prir t flying. In the unlikely event that yu have a warped surface, have a partner heat the cvering f the surface using a heat gun n lw heat setting while yu gently apply a crrective twist t the structure ppsite the warp. Allw the surface t cl while hlding the crrective twist. Release crrectin and check t see that yu were successful. If need be, repeat prcess until surfaces are straight and true Stevens AerMdel.

Pint mdel int wind smthly apply pwer and crrective right rudder. Mdel shuld lift ff in abut 10 feet with applicatin f ¾ thrttle. Climb ut smthly t safe altitude. Trim mdel fr level flight in bth pitch and rll axis. Mdel shuld nt be sensitive t speed (nse up r dwn with pwer changes). If significant pitch attitude changes appear with applicatin f thrttle, re-visit ailern setup as described in this text. Rll mdel inverted. Slight dwnward pressure n elevatr shuld be required t maintain inverted flight. If significant amunts f elevatr crrectin are required t maintain inverted flight, revisit CG setup and ailern setup as described in this text Stevens AerMdel. Page 26 f 34
