The Fokker Dr.1 is one of the most famous and recognizable fighter planes of World War One. The Fokker Dr.1 (Dr standing for Dreidecker or 3
wings) was designed by Reinhold Platz and was ordered into production on July 14, 1917, in response to the success of the British Sopwith Triplane
earlier in the year. The first production model of the Fokker Dr.1 was delivered personally by Tony Fokker to the Red Baron, Rittmeister Manfred
von Richthofen, and shortly after that in August of 1917 it made its first appearance in combat.
Pilots were impressed with its maneuverability and soon scored victories with the nimble triplane. In the hands of an experienced pilot, the Fokker
Dr.1 was a formidable dogfighter. The three wings produce tremendous lift which, combined with its small size and weight, meant it could out climb
and out-turn almost any opponent.

  • Page 10 step 2: instAlling the eleVAtor Control horn IMPORTANT The elevator pushrod exit slot is on the right side of the fuselage. When installing the control horn in the next procedure, it's important to install the control horn so that it's toward the bottom of the elevator and will be on the right siDe of the fuselage when the stabilizer assembly is mounted. ❑ Cut away the covering material from over only the bottom of the control horn mounting slot in the elevator. Please see the important note above. ❑ Glue one control horn into the mounting slot, making sure that the control horn is facing forward. step 3: mounting the stAbiliZer Assembly ❑ Cut away the covering material from over the stabilizer mounting holes in the fuselage and from over the top and bottom of the mounting holes in the stabilizer. IMPORTANT Don't skip the next procedure. The C/A will harden the surrounding plywood, preventing the threads from stripping when you install the machine screws. ❑ Apply a couple of drops of thin C/A into the stabilizer mounting holes in the fuselage and let it dry completely. ❑ Mount the stabilizer to the fuselage, using the two M3 x 25mm machine screws provided. IMPORTANT Be careful not to overtighten the machine screws or you'll crush the stabilizer. The screws need only be tightened snugly. step 4: hinging the ruDDer ❑ Cut away the covering material from over the control horn mounting slot in only the left side of the rudder.

    ❑ Cut two hinge slots in the leading edge of the rudder, equally spaced between the top and bottom, then slide the hinges into place, using the same techniques that you did to install the hinges in the elevator. IMPORTANT As with the elevator, make sure to cut the hinge slots on the centerline of the leading edge. ❑ Cut the corresponding hinge slots in the back of the fuselage, then hinge the rudder to the fuselage, using the same techniques that you used to hinge the elevator to the stabilizer. ❑ After allowing the C/A to completely cure, gently pull on the elevator and rudder to check the integrity of the hinges. The hinges should hold securely. If one or more hinges is loose, apply more C/A to the hinge(s). eleVAtor AnD ruDDer Control systems instAllAtion you'll neeD the FolloWing pArts From the kit: ❑ (2) Carbon Fiber Pushrods (Long) ❑ (2) Heat-Shrink Tubing ❑ (2) Prebent Wires with Z-Bends you'll neeD the FolloWing tools AnD supplies: ❑ Kwik Bond Thin C/A ❑ Modeling Knife ❑ # 1 Phillips Head Screwdriver...

    ❑ With both the rudder and the rudder servo centered, cut off the pushrod right at the front of the control horn. ❑ Attach the remaining prebent wire into the outermost hole in the control horn, then secure it to the pushrod, using the remaining piece of the heat-shrink tubing. IMPORTANT Remember to double-check that both the rudder and the rudder servo are centered before shrinking the heat-shrink tubing. lAnDing geAr instAllAtion you'll neeD the FolloWing pArts From the kit: ❑ (1) Gear Wing ❑ (2) Landing Gear Struts ❑ (2) Main Gear Wheels ❑ (4) Aluminum Brackets (U-Shaped) ❑ (1) Carbon Fiber Axle ❑ (2) Aluminum Brackets (Straight)
  • Page 14 step 2: instAlling the lAnDing geAr struts ❑ Cut away the covering material from over the landing gear strut mounting slots in the top of the gear wing. IMPORTANT The landing gear struts are not the same. One is narrower and one is wider. The narrower strut should be toward the back of the gear wing (A) and the wider strut should be toward the front of the gear wing (b). ❑ Install the landing gear struts into the predrilled holes in the mounting slots. ❑ Secure the landing gear struts to the gear wing using the two straight aluminum brackets and four M2 x 8mm wood screws. Center the brackets over the landing gear struts, then mark and drill 1/16" (1.6mm) pilot holes for the wood screws. PRO TIP Apply a drop of thin C/A into each pilot hole to strengthen the surrounding plywood. step 3: instAlling the geAr Wing Assembly IMPORTANT Pilot holes have been predrilled into the fuselage at the landing gear strut bracket mounting locations. You should be able to see the pilot holes underneath the covering material if you look carefully. After you remove the covering material from over the pilot holes, do as we recommend above and apply a drop of thin C/A to each of the pilot holes to strengthen the surrounding plywood. ❑ Secure the front landing gear strut to the fuselage, making sure that the landing gear strut is centered with the fuselage sides, using two u-shaped aluminum brackets. ❑ Secure the rear landing gear strut to the fuselage, making sure that the landing gear strut is centered with the fuselage sides, using the remaining two u-shaped aluminum brackets.

  • Page 16 step 2: instAlling the Center Wing ❑ Cut away the covering material from over the top and bottom of the wing-screw mounting holes in the center wing, then cut away the covering material from over the outer wing strut mounting slots in both the top and the bottom of the wing. ❑ Apply a couple of drops of thin C/A into the center wing mounting holes in the fuselage and let it dry completely. IMPORTANT There are a total of four outer wing struts included. For this step, make sure that you are using the two that are labeled "DOWN". These are for the bottom wing. "DOWN" is lasered on the lower mounting tab. Before installing the two outer wing struts in the next procedure, make sure that you install them so that they are angled forward and that mounting tab with the "DOWN" label is glued into the bottom wing. ❑ Fit and glue the two outer wing struts into the mounting slots in the top of the bottom wing. IMPORTANT Again, make sure that you install the outer wing struts so that they are angled forward and that the mounting tab with the "DOWN" label is glued into the wing. IMPORTANT In the next two procedures, you'll install the center wing. Do not glue the outer wing struts to the center wing. If you do, it will be impossible to remove either the bottom wing or the center wing from the fuselage. The outer wing struts fit into the center wing without using glue.
