3 Pilot-1 is pleased to announce the 1/8 scale Wedell-Williams Model 44 Racer as part of the Golden Age Civilian Series. The Pilot-1 Model 44 encompasses the same attributes in quality construction and handling that made the original Wedell-Williams a winning design. In fact, the Wedell-Williams design won more overall races between 1931 and 1936 than any other race plane. From 1932 to 1935, a model 44 won 1 st, 2 nd, 3 rd against the Gee Bee R-1 and Gee Bee R-2, which by the way placed last. Our engineers have spent countless hours developing a true-to-scale ARF that looks and flies like the full-scale Model 44. There are few airplanes that fly slow like an Aeronca Champ AND fly fast wingtip-to-wingtip with the famous Gee Bee racers. We know you will be pleased with the Model 44. With its beautiful looks, balanced maneuverability, and docile flying characteristics, it is a design that is truly at home in the Winner s Circle!

4 History The Wedell-Williams Model 44 [and in our case, also Race #44 ] was a racing aircraft, four examples of which were built in the United States in the early 1930s. It began as a rebuilding of the partnership's successful We-Will racer of 1929, but soon turned into a completely new aircraft. It was a typical 1930s racer design, a braced, low-wing monoplane powered by a large radial engine and equipped with fixed landing gear in large spats. Model 44s were raced in the 1932, 33, and 34 Bendix Trophy races, as well as the 1934 Thompson and Shell Trophy. In September, 1933 at the International Air Race in Chicago the 44 piloted by Jimmie Wedell set the new world speed record of miles per hour.

6 1. These instructions are written for someone who has assembled at least one or two planes. It is very easy to assemble. However, if you need help, contact a local model airplane flyer or contact us here at Hobby-Lobby.com. Carefully follow each step in the order they appear in this manual. It should take 4 to 6 hours. So, let s get started! 2. Start by removing the ailerons and CA hinges from the wing. They should not be glued in place from the factory. 3. Prepare CA hinges for installation as shown. When bending the hinges in half, take careful note of the direction of precut slots. You will need to bend the hinges back and forth several times to loosen them up. 4. Insert the bent CA hinges in the aileron precut slots. Use a hobby knife if slots are too tight or not deep enough. 6

7 5. Insert the aileron CA hinges into the wing. The pre-bend in the hinge should allow you to keep hinge 50% in the wing and 50% in the aileron. 6. Use thin CA to glue hinges in place. Make sure there is an even gap on each end of the aileron. The aileron is deflected slightly during gluing. Use 2 to 3 drops of thin CA per hinge, per side. Note the tight fit between the aileron and the wing. 7. Depending on the type of servos you are using, you may need to trim the balsa blocks as shown. 8. Turn on radio. Make sure the aileron trim is centered and all programming is reset to neutral. Install servo arm 90º to the plate and located in the center of slot. Install the servo screws into the balsa blocks. 7

8 9. Trim the opposite horn flush. Drill the outer servo arm hole out to 3/64 (1.2mm) diameter. This hole is located 1/2 (13mm) from the center of the servo screw 10. Use tape to secure pull-string and the 12 servo extension wire. Pull servo wire through wing. 11. Install aileron horn into aileron hole. Use a hobby knife to remove covering material from under the horn. Then install control horn in place and glue with thin CA. Drill out middle hole in horn with 3/64 (1.2mm) drill, or use hobby knife point to enlarge hole. Install aileron pushrod as shown. 12. Install four short sheet metal screws to hold cover in place. Repeat for opposite wing. 8

9 13. Insert the Elevator into slot in the fuselage. 14. Now, insert horizontal stabilizer into slot as shown. 15. Align horizontal stabilizer so that holes for vertical stabilizer are perfectly aligned. We will glue the entire tail in a later step, so do NOT glue just yet. 16. Insert vertical stabilizer into fuselage as shown. Again, do NOT glue.. 9

10 17. The Hobby-Lobby.com R&D department has determined that the CA hinges for the Elevator and Rudder are too stiff as supplied in the kit. We recommend that you cut away 2/3 of each hinge as shown. Take care to cut along the precut slits in the hinge. There is still plenty of strength left in the hinge for a model this size. You will use four (4) small CA hinges on the Elevator and two (2) on the Rudder 18. Insert CA hinge into elevator and horizontal stabilizer. You will have to flex elevator just a little bit. The x shows the portion of each CA hinge to trim away. 19. Use thin CA to glue hinges in place. Use 2-3 drops per hinge 20. Use thin CA to glue the Vertical and horizontal stabilizer in place. Be very careful with application. A super thin applicator tip on your CA bottle will help with this step. Use CA debonder on paper towel to clean up any CA drips. 21. Remove covering from bottom of Rudder as shown. Also install the Rudder control horn and center it in rudder. Use thin CA to glue it in place. 10

11 22. Insert tailwheel into the predrilled hole in the rudder. No glue is necessary. 23. Insert the trimmed CA hinges in Rudder and install as shown. Use 2-3 drops of thin CA to secure hinges in place. 24. Attach tailwheel bracket to fuselage with two (2) sheet metal screws. Align tailwheel with Rudder and tighten set screw as shown. 25. Install the servos as shown. Turn on radio. Make sure the Elevator and Rudder trims are centered and all programming is reset to neutral. 11

12 26. Assemble the ends of the rudder pull-pull cables as shown. Make sure to double loop the cable through the crimp and compress crimp with needle nose pliers. Attach the left rudder cable to the right control arm and vice-versa. The cables inside the fuselage should cross each other once and make an X. 27. Insert the elevator pushrod into the left pushrod tube. Install the servo horn onto the z-bend and then onto the servo. Do not forget to install the servo screw. Trim the opposite side of the horn with pliers as shown. 28. Align horn with elevator pushrod and insert horn points through elevator. Remove covering around horn. Insert horn into elevator and glue with thin CA. 29. Use fine permanent marker to mark music wire adjacent to control horn holes. This is where you will make a 90-degree bend in the wire. Do NOT bend wire quite yet. 12

13 30. Insert the Elevator pushrod standoff T and the plastic clevis retainer clip as shown. 31. Use needle nose pliers to bend elevator pushrod 90degrees toward horn. Install plastic clevis retainer as shown. 32. Position elevator pushrod support T as shown. Make sure the pushrod is straight. While holding fuselage upside down, use 5- min epoxy to glue support T to covering. *Note: Be very careful here. Do not to glue the rudder cable! 33. Temporarily hold rudder in the center position. Here we have use wooden dowel scraps and a rubber band. The idea is to keep rudder centered while we adjust the rudder pull-pull cables. 13

14 34. Assemble the rudder pull-pull cable as shown. Make sure the radio is on and all trims are centered. Lightly pull slack out of cable 35. Compress cable crimp with needle nose pliers. Repeat for opposite side. Remove the temporary brace on the rudder. 36. Remove the forward tailwheel bracket screw. Use a crimp tube to make a loop in the end of the cable and compress with needle nose pliers. Insert screw through wire loop and reinstall as shown. 37. Feed wire cable through predrilled holes in horizontal and vertical tail as shown. 14

15 38. Using a wire crimp, route a wire loop around the forward tailwheel bracket screw as shown. Use needle nose pliers to compress the wire crimp. Cut off excess wire and tighten screw. Note: use thin CA on each crimp tube after compressing with pliers. This also goes for all crimp tubes used in assembly. 39. This photo shows the completed tail brace wire highlighted for emphasis. 40. Insert the landing gear legs into the fuselage slots. 41. Insert the plywood retainer blocks as shown. The notch faces toward the aircraft centerline. 15

16 42. Some light trimming may be needed but the blocks should be flush. Use thin CA to glue blocks in place. 43. Locate the wheel pants, main wheels, and wheel collars. 44. Partially insert the wheel pant onto the landing gear wire leg. Slide the inboard wheel collar onto wire. 45. Install the main wheel and outboard wheel collar. 16

17 46. Insert the end of the landing gear wire into the outboard wheel pant plywood block. 47. Fully slide wheel pant assembly inboard until wire is seated in molded slot. Tighten wheel collar set screws. Use canopy glue to attach landing gear wire end to plywood block as shown. 48. Insert the landing gear cover. Use canopy glue to attach to wheel pant as shown. Use tape to temporarily hold in place while glue dries. 49. Attach landing gear leg covers with two (2) plastic straps and very short sheet metal screws as shown. Plastic Straps 17

18 50. Insert Carbon Fiber wing tube into fuselage. Slide each wing panel onto wing tube and feed aileron servo wire into fuselage. Use two (2) small pieces of clear tape on bottom of wing joint per wing panel to hold each wing panel in place. 51. Solder the electronic speed control (ESC) connectors and DEANS Ultra battery connector as shown. 52. Connect the motor and ESC wires together. For AXI motors, connect the Red-to-Red, Black-to-Yellow, and Yellow-to-Black. (Mismatching any two wires will make the motor turn the proper direction for our application.) 53. Install the motor to the motor mount using the motor supplied counter-sunk screws. Make sure to install the aluminum wheel collar on the rear motor shaft as shown. This distributes the prop loads into the rear bearing. 18

19 54. Install the motor onto the firewall with (4) machine screws. 55. Insert the ESC through the nose section and route along right side of plane. 56. Use small tie wraps or tape to secure ESC wires. 57. Fabricate and install a battery guide block out of scrap balsa or foam. Use 5-min epoxy to glue it in place. This will help protect the battery from rubbing against the rear motor shaft and engine mount screws

20 59. Enlarge hole in plastic dummy engine with a dremel tool and ½ sanding drum. You could also carefully use your hobby knife or canopy scissors. 60. Make sure you have at least a 1/8 (5mm) of clearance between the motor and dummy engine. 61. Install cowl, prop, and spinner. It should look like this from the top of the cowl. There should be approximately ½ gap between cowl and propeller. 62. Install battery hatch. 20

21 63. Install canopy with canopy glue and temporarily tape in place while glue dries. The back edge of the canopy should be flush with the battery hatch aft bulkhead. 64. 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) is recommended. 65. Adjust Elevator HIGH RATE travel to get 1/2 (12mm) up and 1/2 (12mm) down. Use 40% expo to soften the center travel per your radio manual. (JR/Spektrum +40% and Futaba/Hitec -40%) 12mm 12mm 66. Adjust Elevator LOW RATE travel to get 5/16 (8mm) up and 5/16 (8mm) down travel. Use 30% expo to soften the center travel per your radio manual. (JR/Spektrum +30% and Futaba/Hitec -30%) 8mm 8mm 21

22 67. Adjust Rudder HIGH RATE travel to get 1/2 (12mm) left and 1/2" (12mm) right Use 30% expo to soften the center travel per your radio manual. (JR/Spektrum +30% and Futaba/Hitec -30%). 12mm 12mm 68. Adjust Rudder LOW RATE travel to get 5/16 (8mm) LEFT and 5/16" (8mm) RIGHT. Use 20% expo to soften the center travel per your radio manual. (JR/Spektrum +20% and Futaba/Hitec -20%). 8mm 8mm 69. Adjust each aileron s HIGH RATE up and down travel to get 7/8 (22mm) using the end point adjustment. Use 40% expo to soften the center travel per your radio manual. (JR/Spektrum +40% and Futaba/Hitec -40%) 22mm 22mm 70. Adjust each aileron s LOW RATE up and down travel to get 5/8 (16mm) using the end point adjustment. Use 30% expo to soften the center travel per your radio manual. (JR/Spektrum +30% and Futaba/Hitec -30%) 16mm 16mm 22

23 71. The use of a very small Aileron-to-Rudder mix is also suggested. We used a mix of 10%. This means when you move the aileron control stick to its full position, the rudder will also move about 1/16 (3mm) in the same direction of the control stick. 72. Insert your flight battery and secure with Velcro straps. We have also used Velcro on battery and on floor of battery compartment. Note: You may need to move installed Velcro straps depending on battery being used and method of securing battery. 73. Make a mark on each wing 2-1/8 (54mm) 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. Make a mark with a pen in battery compartment so that you place the battery in the same place every time. 74. If you have moved the flight battery as far forward as possible, you may have to use a small amount of stick-on lead weight inside of the cowling to move center of gravity (CG) forward until model balances level. Now you are finished and ready to go fly! 23

24 75. Before you install the Scale Flying Wires, please review steps These next few steps show how easy it is to remove the battery hatch with the flying wires installed. 76. Start by removing the flying wires from the bottom of the fuselage. Then lightly pull the flying wires until the crimp hits the inside of the wheel pant. 77. Lightly pull some slack in the upper flying wires. 78. Lift up battery hatch. 79. And set it aside. All the flying wires are still attached. No screwdrivers required! Insert your charged battery, hook the wires to the wheel pants and you are ready to fly. Easy as 1-2-3! 24

25 80. We recommend installing the scale flying wires only if you are an experienced flyer and will not be flying from grass or rough runways. 81. This is how the flying wires will look when you are finished with installation. Use this photo as an overall guide. There is also a 3- view drawing at the back of this manual. 82. Start with the lower forward flying wire. Insert cable through wheel fairing hole and around landing gear wire. Then insert back through same hole. 83. Use a crimp tube to fasten wires. Compress crimp with needle nose pliers. Then use thin CA on crimp to secure wires. 25

26 84. Insert sheet metal screw into predrilled hole in lower surface of wing that is near leading edge ahead of servo cover. 85. Remove screw and use thin CA in hole to harden balsa block inside wing. 86. Install sheet metal screw into hole. Loop cable through crimp tube, around screw, back though crimp tube and pull cable lightly until all slack is removed. Compress crimp tube with pliers and add thin CA to tube for security. Repeat for opposite wing. 87. Assemble a loop on end of cable and compress crimp & CA. Install small spring to loop and attach to forward landing wire on landing gear. 26

27 88. Insert opposite end of cable through wire loop on other gear leg and crimp/ca. You have now completed the forward fixed flying wire cable. 89. Install four (4) sheet metal screws into predrilled holes on battery hatch. 90. Use CA glue to harden area around each of the screws from the inside of battery hatch. 91. Loop long flying wire cable around the forward battery hatch screw, compress crimp and CA. 27

28 92. Insert cable through forward flying wire hole located about halfway out on wing. 93. Insert cable through wheel pant as shown. (Note: Aft cable is also shown installed in this photo. Both cables will be routed though same hole.) Repeat last few steps for the rear flying wire cable. 94. Install crimp and spring. Loop both ends of cables as shown. Do not compress crimp and do not CA quite yet. 95. Install wire connector with sheet metal screw into balsa landing gear block on opposite side of fuselage and use thin CA to secure. Attach spring to this connector. Lightly pull all slack from fore and aft cables. 28

29 96. While pulling tension on spring with cable ends, use needle nose pliers to compress crimp. 97. Use thin CA to secure crimp and trim away excess wire. 98. Here is a picture of the steps completed so far. The dashed and/or color lines represent each individual cable. 99. Repeat steps 89 thru 95 for opposite wing flying wires. Make sure to pull slight tension on spring before compressing crimp and CA. 29

30 100. When complete, it should look like this When removing battery hatch, you will only have to remove one (or both) of the spring hooks from the fixed snap rings You are now ready to fly! 30

31 Preflight Whether 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: 2-1/8 (54mm) aft of the 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 Wedell-Williams #44 is a real pleasure to fly. Takeoffs, landings, and scale aerobatics are easy and well behaved. 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. You can expect flight times of 7 to12 minutes depending on battery used and throttle management. We hope you enjoy your Pilot-1 Wedell-Williams #44 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.
