2 Before starting, use the Contents list to take an inventory and make sure it is complete. If any parts are missing or are not of acceptable quality, contact Hobby-Lobby.com Support Contents List Fuselage Main Wing w/nacelles Horizontal Stabilizer Vertical Tail and Rudder Wing Joiner Tube 1350Kv Brushless Motors X 4 30A Brushless ESC s X 4 3-Blade 7x6 Propellers (2-right hand, 2 left hand) Servoless Retractable Main Landing Gear Hardware, Y-Connectors, Additional Items Required (Not Included) 6-channel Aircraft Radio w/ Receiver (minimum) mah, 3-cell, 11.1V Lipo batteries Lipo Battery Balance Charger External BEC (ERCBEC6) Soldering iron and electrical solder 2

3 1. Locate the 2 main wing panels and the tube joiner and test fit them. 2. Mix some 5-minute epoxy and apply to the root of one wing panel. 3. Slide the 2 wing panels together and hold them in alignment until the epoxy sets. NOTE: Clean up any excess epoxy before it sets with a paper towel and a small amount of rubbing alcohol 4. Locate the 4 plywood reinforcements. The two with the holes install flat at the front and rear of the wing and the other two install in slots in the wing center section. 3

4 5. Apply epoxy to both sides of the ply piece as shown in the photo and install in the slot in the forward part of the wing center section. 6. After the epoxy has set turn the wing over and glue the plastic wing bolt reinforcements into place. 7. Turn the wing topside up and locate the 4 engine nacelles. Each nacelle is labeled L1, L2 and R1 and R2. 8. Dry fit the nacelles to check fit. 4

5 9. Apply epoxy and slide nacelle into position, make sure to route the motor wires into the wire channel. 10. Align nacelle with wing and hold in position till epoxy sets. NOTE: If epoxy squeezes out of joints, it can be wiped off with a paper towel and a little alcohol. 11. Continue the process on remaining nacelles. NOTE: We recommend gluing the nacelles one at a time. 12. There are four 30A ESC s assembled into two pairs. Photo shows one pair of ESC s to be supplied by one battery pack. This pair will power one outboard motor on each wing. The other pair of controllers (not shown) will power the inboard motors from a second battery pack. 5

6 13. From the topside of the wing thread the three motor wires from one controller into the wire channel on the left wing and repeat the process for the wires from the second controller to the channel in the right wing. 14. Photo shows correct wiring for one pair of controllers. 15. Plug the controller wires into the motor wires. 16. Neatly press the wires into position in the channel 17. Locate the aileron Y-extension and route it down both wire channels. 18. Plug aileron servo in and tape the connection to prevent accidental loss of signal. 6

7 19. Feed the second set of ESC wires into the channel from the wing center section. 20. Feed the ends into the inboard motor nacelle. The connection to the motor will be from inside the landing gear opening on the bottom of the nacelle. 21. Do not install the channel cover at this time. 22. Place the wing onto the fuselage. 23. Locate the 6 screws and 2 washers to screw wing into position. 24. Screw wing into position with the included screwdriver. 25. Locate horizontal stabilizer and dry fit it into position. 7

8 26. Locate tail gunners canopy and install in position at rear of fuselage. 27. Locate vertical fin and rudder and feed rudder servo wire down through the vertical stabilizer. 28. Slide vertical fin into slots in horizontal stabilizer. 29. Photo shows tail parts in position and ready to screw from the underside. 30. Remove the plastic cover from the bottom rear of the fuselage. 31. Glue the two plywood reinforcements into the fuselage. 8

9 32. Locate the tail mounting screws and washers. 33. Screw tail parts into position. 34. At your discretion tail parts can be glued into position. This is not required; they can be just screwed into place. 35. Plug the rudder servo into the servo extension. Please pay attention to the plug orientation for a good circuit. 36. Glue cover back into position on the bottom of the fuselage with Uhu Por or similar glue. 37. Locate the four 30A ESC s in the cockpit area. 38. Carefully cut the heat shrink covering at the edges of the finned heat sink. 9

10 39. Remove the section of plastic heat shrink and discard. 40. Place the four 30A ESC s side by side across the fuselage with the heat sink facing up. They are held in place by the Velcro across the fuselage. 41. We strongly recommend the use of an external BEC with this model. 42. When using an external BEC it is necessary to disable the BEC s that are included in the 30A ESC s. 43. Locate the 4 connector Y-Harness and remove the red wire from the lead that plugs into the receiver. (see photo) 44. To remove the red wire, use a small blade like a #11 Exacto and lift the plastic tab on the side of the plug. With the plastic tab lifted, pull the red wire out of the plastic housing. 45. After removing the red wire, fold it back and tape to prevent shorting. 46. The 4 connector Y-Harness will still control the throttles of all motors when plugged into the throttle channel on your receiver. 10

11 47. Locate one of the dual ESC to Battery connectors (see photo). 48. Remove the black heat shrink from one Black wire and one Red wire. 49. Solder the red wire from your external BEC to the base of the female red bullet connector. 50. Repeat this process with the black wire from BEC to the black bullet connector. 51. When complete the part should look like the photo at right. 52. Apply new heat shrink to the bullet connectors. 53. It is only necessary to power the external from one of the two battery packs. 54. The receiver plug from the external BEC is plugged into the battery channel on the receiver. 55. Photo shows the external BEC and the 4- ESC s (3 visible). 56. Locate your 6-channel receiver to the rear of the ESC s and BEC. 57. Some additional detailing can be done to the cowls all that is required is a small paintbrush and a small bottle of silver model paint. 11

12 58. A little detailing goes a long way. 59. The kit includes both right and left hand propellers. The rotation of the propeller is defined by looking at the propeller from behind. A right hand prop rotates clockwise and a left hand counterclockwise. 60. On our model we suggest that the right hand props be installed on the right wing and the left hand ones on the left wing. 61. Slide the prop onto the prop shaft and engage the hex shaft of the motor into the hex recess on the back of the prop. 62. Add one small washer and the 3mm Nylock nut to the shaft. 63. Using the included wrench, snug the nut down on the prop. DO NOT OVERTIGHTEN 64. Screw the silver prop spinner onto shaft. 65. From the decal sheet peel and stick a prop decal on each of the blades at about the mid point of the blade as shown. 12

13 66. Completed prop 67. Locate the guns and install with a small amount of glue. Chin turret shown. 68. Waist guns in position. 69. Cheek machine guns insert into bottom window opening on each side of nose. NOTE: The windows on the front of the cheek guns have been removed to allow cooling air to enter the fuselage. 13
