Introduction & History

The Stinson 108 “Voyager” was a popular general aviation aircraft produced by the Stinson division of the American airplane company Consolidated Vultee, from immediately after World War II to 1950. It was developed from the prewar Model 10A Voyager. Stinson was bought by Piper Aircraft and production continued for a few years at a slow rate under the new owner. The fuselage was of fabric-covered steel tube. Aftermarket modifiers have obtained supplemental type certificates (STC) allowing conversion to an aluminum covering. Many different engines have been installed in the 108 by STC such as the Lycoming O-360, Franklin 220, and Continental O-470.

One distinctive feature was the partial leading edge slot installed on the wings and aligned with the ailerons on the trailing edge, ensuring that the portion of the wing containing the aileron remains unstalled at higher angles of attack, thus contributing to docile stall behavior.

Total production of the Stinson Model 108 was 5,259. Stinson delivered 5,133 aircraft and Piper delivered 126 aircraft.

1. This manual will help you assemble your Hobby-Lobby.com Pilot-1 airplane step-by-step. It does assume that this is not your first airplane. If you need assistance, please ask a local flyer, visit www.rcgroups.com, or call us here at Hobby-Lobby.com. Let’s start by preparing the aileron servos and aileron wire extensions. Wrap the connection with tape or use heat shrink tubing to prevent an accidental disconnect.

2. Make sure servo is centered and install large servo horn and screw. Test fit servo on servo cover.

3. While holding servo horn centered in the slot, use 5-min epoxy to glue servo blocks in place as shown. Be careful to align side-to-side and up-and-down.

4. After 5-min epoxy has set, install servo screws into blocks. Use wire cutters to remove unused side of servo arm.

7

5. Tape the aileron wire extension to the end of the preinstalled string. Pull string and wire through wing panel. Repeat for opposite wing panel.

6. Install each aileron servo cover with four (4) small sheet metal screws.

7. Bend CA hinges as shown. Flex hinges completely back and forth several times to loosen them before installation. *Note the direction of the slots in the hinges.

8. Insert CA hinges and aileron into wing. Make sure alignment is good with even spaces at each end of aileron.

8

9. With aileron deflected downward and fitted with no gap between the leading edge of aileron and wing, CA each hinge. Use thin CA, 2 drops per hinge per side.

10. Temporarily install aileron control horn onto the aileron.

11. Trace around horn and remove covering with hobby knife.

12. Insert horn with sheet metal screws and glue in place using thin CA to add extra security.

9

13. Temporarily install the wing and landing gear. Insert wing attachment machine screws or use masking tape to hold in place.

14. Trial fit vertical stabilizer. When satisfied with alignment, use 5-min epoxy glue to attach to fuselage. Maintain vertical alignment until glue dries. *Note: Some fuselage twist can be removed with light heating of covering with heat gun.

15. Install carbon fiber spar tubes as shown. You have a choice to use one or two elevator servos. *Note: If you are using just one servo, you will need to install the steel elevator joiner as shown. Do not use steel joiner if you are using two servos.

16. Install horizontal stabilizers onto CF tubes. Trial fit the elevators. When satisfied with fit, use 5-min epoxy to glue just the horizontal stabilizers in place. Use a paper towel and rubbing alcohol to remove excess epoxy before it dries.

10

17. Maintain proper horizontal alignment while epoxy dries. Sight with wing installed or main wing spar tube for level. Note: If necessary, some twist can be corrected with a covering heat gun on low setting.

18. Using the same technique as the ailerons to install the elevators. Pre-bend the CA hinges, bend back and forth several times, install, check for alignment, and CA each hinge 2 drops per side.

19. Remove covering from lower front of rudder slot. Insert and glue tailwheel wire into predrilled hole. Use 5-min epoxy for this step.

20. Install rudder and CA hinges using thin CA, 2 drops per hinge, per side.

11

21. Install two (2) sheet metal screws into the tailwheel bracket.

22. Install the vertical stabilizer fairing with UHUpor contact cement. You can use a paper towel and lighter fluid to remove any excess glue. Use masking tape to secure fairing until glue is dry.

23. Dual Elevator Servo Option. Install pushrods and servos as shown. Make sure servos are centered before installing horns. The outer holes may need to be drilled out slightly for the “z-bend” in the wire. We have engineered the elevator servo placement so that you have the option of using a standard “y-harness.” Note: You will need to install one of the servo screws at an angle.

24. Single Elevator Servo Option. When using the steel elevator connector, you can use a single servo to drive both elevators. Install the elevator and rudder servo as shown.

12

25. Install nut, springs, and pushrod clevis onto the elevator pushrods.

26. Install elevator control horn onto pushrod clevis. Drill holes through elevator and install with machine screws and nylon top plate as shown. If you have difficulty aligning screws, drill out holes in balsa slightly oversized.

27. Center elevator servo and adjust clevis as needed. Slide retainer spring in place and secure with nut.

28. Install and center Rudder horn. Use thin CA to glue in place.

13

29. Fabricate the rudder servo ends of the pull-pull cables as shown. After compressing crimps with pliers, use thin CA to add extra security to crimp.

30. Use a servo horn with holes spaced apart approximately 1-3/8” (35mm).

31. Install rudder servo horn and clevises as shown.

32. Insert scrap piece of music wire or carbon fiber through slot and hole in rear bulkhead. Use it to fish rudder cable from servo.

14

33. Here we have used thin CA to attach wire to carbon fiber rod. Pull rod and cable through fuselage to rudder horn.

34. Make sure rudder servo and rudder is centered. Compress wire crimp with pliers and use thin CA to add extra security to crimp.

35. Install landing gear legs with machine screws. Use a short screwdriver or 90 degree ratchet driver.

36. Slide landing gear covers over gear legs and into place as shown. Use UHUpor contact cement to secure.

15

37. Install wheel pants with small machine screw and nut. Use UHUpor contact cement to secure nut and wheel pant.

38. Install main wheel axle and nut.

39. Slide inner wheel collar and wheel onto axle. Tighten nut and machine screw. Use blue locktite or UHUpor glue to secure nut and axle.

40. Install outer wheel collar, center wheel in wheel pant, and tighten wheel collars. Make sure that wheel can rotate freely on axle.

16

41. Use UHUpor contact cement to attach outer axle to wheel pant block. This will add quite a bit of strength to wheel pants.

42. Solder motor to speed control. In our application, on the motor side of the ESC, connect black to yellow, red to red, yellow to black. That will assure motor runs the correct direction. Solder your battery connector on the other end of ESC. Here we have used the Male Deans Ultra plug. As with any electric plane, use high quality connectors designed for R/C applications and make good solder connections.

43. Install AXI motor onto motor box with motor wires coming out the top as shown. The battery will eventually Velcro to the bottom of motor mount.

44. Install motor mount to firewall with four (4) machine screws. Route the ESC and wires along the side of the fuselage.

17

45. Cut four (4) strips of paper the same width of cowling blocks (patterns included in the back of this manual). Use tape to install paper strips over each cowling block as shown.

46. Install cowling. Make sure the paper strips are on outside of cowl. Align cowl with propeller shaft face 5mm (3/16”) in front of cowl.

47. Also align cowl so that motor shaft is centered and side paint stripes align. Use masking tape to hold cowl in position for next few steps.

48. Drill a 1mm (1/32”) pilot hole through paper strip, cowl, and wood mounting blocks for each of the four (4) screws.

18

49. Fold paper strips out of the way and slightly enlarge the hole in the fiberglass cowl only! Here we are 1.5mm drill bit but you could use a hobby knife or body reamer. This is done to keep cowl from cracking when inserting the cowl sheet metal screws.

50. Install the four (4) sheet metal screws. Remove paper strips and masking tape. Install APC 10x7 “E” prop.

51. Use the template in the back of this manual to fabricate an instrument panel cover from 600 grit sandpaper. Install with UHUpor contact cement. You may also wish to create a panel with instruments from this template.

52. Cut a dash cover out of 600-grit sandpaper. Install with UHUpor contact cement.

19

53. Use canopy glue to install windshield. Use a wet paper towel to clean up any mess before glue dries. Use masking tape to hold everything in place while the glue dries.

54. Install wings. Insert machine screws into wing attachment tabs.

55. Sight wing from behind the plane looking for any wing twist or warp. If found, twist wing into desired position and use a covering heat gun on low setting to remove wrinkles. You may also wish to use an incidence meter to set wings at zero degrees or with slight washout (i.e. wing leading edge slightly lower than trailing edge).

56. Prepare the wing struts for assembly. Pre-insert sheet metal screws into struts.

20

57. Place scrap foam or towel under center section of wing for support. You do not want any load placed on wing tips while installing struts. This step will set about 2 degrees of dihedral in wing. The carbon fiber spar holes in the ribs automatically set this angle.

58. Install wing strut to the fuselage with a sheet metal screw behind the landing gear as shown.

59. When you are satisfied with the straightness of the wing, use a sheet metal screw to attach the forward wing strut at 1-3/8” (35mm) from the Leading Edge of the wing.

60. Use a sheet metal screw to attach the aft wing strut at 5” (127mm) from the Leading Edge of the wing.

21

61. Install battery Velcro. Install receiver and secure wiring.

62. Make a mark on each wing 2” (50mm) back from the leading edge. Install battery and balance model at these marks with the tips of your fingers. Move the battery fore or aft until airplane balances with fuselage level or slightly nose down. Make a mark in battery compartment so that you place the battery in the same place every time. Small stick-on lead weights may also be necessary inside engine cowl.

63. Please refer to your radio manual for the following few steps. Please note that some computer radios have separate settings for exponential for high and low rate positions. Make sure you double check all settings before flight. If you are new to programming, check with a local experienced modeler or hobby shop for assistance. The use of Exponential (expo) and Aileron-Rudder mix is recommended.

64. Adjust Elevator HIGH RATE travel to get 9/16” (15mm) up and 9/16” (15mm) down. Use 25% expo to soften the center travel per your radio manual. (JR/Spektrum +25% and Futaba/Hitec -25%)

65. Adjust Elevator LOW RATE travel to get 3/8” (10mm) up and 3/8” (10mm) down travel. Use 10% expo to soften the center travel per your radio manual. (JR/Spektrum +10% and Futaba/Hitec -10%)

66. Adjust Rudder HIGH RATE travel to get 9/16” (15mm) left and 9/16" (15mm) right. Use 20% expo to soften the center travel per your radio manual. (JR/Spektrum +20% and Futaba/Hitec -20%).

67. Adjust Rudder LOW RATE travel to get 1/2” (12mm) LEFT and 1/2" (12mm) RIGHT. Use 10% expo to soften the center travel per your radio manual. (JR/Spektrum +10% and Futaba/Hitec -10%).

68. Adjust each aileron’s HIGH RATE travel to get 5/8” (17mm) UP and 3/16” (5mm) DOWN using the end point adjustment. Use 20% expo to soften the center travel per your radio manual. (JR/Spektrum +20% and Futaba/Hitec -20%)

Preflight If you are new to flying R/C aircraft, or a seasoned modeler, we recommend you have a fellow R/C modeler help you with the first flight. Some items you will need to complete on your first preflight are:

1. Aircraft assembled correctly and ready for flight. 2. All control throws and expos are set per this manual. 3. Transmitter fully charged and on correct model. 4. Aircraft balances at the recommended location. (2” aft of wing Leading Edge) 5. Flight Battery is fully charged and secure. 6. All electronics are operating correctly, proper direction, and secure. 7. Complete a radio Range Check per your radio manual. 8. Balance propeller and make sure it is secure. 9. Wait for a calm or light wind day for first flights. 10. If you are new to R/C flying, consider having an accomplished flyer make the first

flight and trim the aircraft. A buddy-box training system is also very helpful.

Flying You will soon find out the Pilot-1 “Voyager” is a real pleasure to fly. Takeoffs, landings, and light aerobatics are easy and well behaved. Even if you have never flown a tailwheel airplane before, the Pilot-1 “Voyager” should be an easy transition. We personally recommend the use of a buddy-box training system for new pilots. Landings are best accomplished by “three-pointing.” This means that all three wheels should touch at the same time and a little up-elevator is held until the aircraft comes to a complete stop. Except for takeoff and climb, you will only use about 1/3 throttle to maintain a scale flying speed. You can expect flight times of 15-20 minutes depending on battery used and throttle management. We hope you enjoy your Pilot-1 “Voyager” as much as we do! Happy Landings!

WARNING – THIS IS NOT A TOY!

Radio controlled model aircraft are capable of inflicting serious injury and/or property damage if not assembled, operated, and maintained in a competent and safe manner. If you are not already experienced with radio controlled models, we strongly suggest

that you find an experienced modeler to assist you.

Warranty Hobby-Lobby guarantees this kit to be free from defects in both material and workmanship at the date of purchase. This warranty does not cover any component parts damaged by use or modification. In no event shall Hobby-Lobby’s liability exceed the original
