  • Page 3: Introduction

    INTRODUCTION Thank you for purchasing the Modeltech Dragon Lady 60 ARF. Before completing the final assembly of your new airplane, please carefully read through this instruction manual in its entirety. Doing so will ensure your success the first time around!

  • Page 4: Section 1: Our Recommendations

    What Engine Should I Use? The Dragon Lady 60 will accept a wide variety of engines, so which engine you choose really depends on how you want to fly the airplane. For general sport flying, a .61 two stroke or .91 four stroke would be an ideal choice. Either of these engines will provide good overall performance and will pull the airplane through most aerobatic maneuvers with ease.

  • Page 9 Slide both wing panels together with the wing joiner temporarily installed (without using glue). Again, make sure the wing joiner's "V-shape" is toward the top of the wing panels. This will help ensure the proper dihedral angle. Look carefully at the center section joint: the wing panels should fit together tightly with few or no gaps in the joint. If the wing panels do not fit together properly, remove the wing joiner and use 220 grit sandpaper with a sanding block to lightly sand the edges and tips of the joiner, until you are satisfied with the fit.

  • Page 18: Section 12: Main Landing Gear Installation

    While holding the tiller arm firmly against the bottom of the rudder, drill a 5/64" diameter pilot hole through both sides of the nylon clasp and through the rudder. Thread the 2.5mm x 12mm wood screw into one side of the clasp, through the rudder and into the other side of the clasp.
  • Page 19 Step 2: Installing the Wheels & Wheel Pants Using a modeling knife, very carefully cut the wheel opening in each of the two wheel pants, as shown. Use 220 grit sandpaper with a sanding block to carefully sand the edges of the openings smooth. Using a 5/32"...
  • Page 20 After the epoxy has fully cured, carefully drill a 3/8" diameter hole through the wheel pant and plywood plate using the 5/32" diameter hole you drilled previously as a guide. The hole will not be centered within (and might even miss part of) the plywood plate.

  • Page 21: Section 13: Engine Installation

    Remove the wheel collars, wheel and wheel pant from the threaded axle. Using a 5/32" diameter drill bit, drill a hole into the wheel pant and through the plywood plate, at the mark you drew. Carefully install one 3mm blind nut, from inside the wheel pant, into the hole you just drilled.
  • Page 22 Step 1: Aligning the Engine Mounting Beams IMPORTANT If you'll be using an engine that is smaller than 1.08 - 1.20 size, begin by epoxying on the plywood spacer as described below. If you'll be using a 1.08 - 1.20 size engine, skip this procedure.
  • Page 23 Temporarily glue the two engine mounting beams to your engine's mounting lugs using a couple of drops of thick C/A. The location of the engine is not important at this time. It's more important that the beams are square to the mounting lugs. Using a ruler, measure the distance between the holes in the two engine mounting beams.

  • Page 24: Section 14: Fuel Tank Assembly & Installation

    Slide your spinner's backplate onto your engine and secure it in place using your engine's prop washer and nut. Set the engine onto the engine mounting beams. Using a ruler, measure the distance from the firewall to the back of the spinner backplate (front of the thrust washer). Adjust the depth of the engine so the measurement is 5-7/8".
  • Page 25 Using a ruler, measure the distance that the two aluminum tubes protrude from the front of the stopper assembly. This distance should be 3/8". If it is not, adjust the tubes by pushing them forward or backward until you are satisfied with the alignment.

  • Page 26: Section 15: Servo Installation

    Step 3: Installing the Fuel Tank Assembly Cut two pieces of silicon fuel tubing to a length of 8" and install them onto the aluminum tubes at the front of the tank. For your convenience, we suggest marking the free ends of the tubing "vent" and "pick-up" so you don't confuse them when it comes time to connect them to the engine later on.
  • Page 27 BEFORE INSTALLING THE SERVOS, PLEASE READ THIS! The Dragon Lady 60 is designed to use four servos. For the elevator and rudder servos, we have designed several different options for their mounting location. Typically, these servos would be mounted inside the fuselage on a plywood tray, which we have provided.

  • Page 28: Section 16: Throttle Linkage Installation

    Remove the servo tray. Using a modeling knife, cut away and remove the covering material from within the outline you drew. Glue the servo tray into place using a generous amount of 5 minute epoxy. Remove any excess epoxy using a paper towel and rubbing alcohol, and allow the epoxy to set up before proceeding.
  • Page 29 Enlarge the fourth hole out from the center of the servo arm using a 5/64" drill bit. Install the adjustable servo connector into the servo arm. IMPORTANT When threading on the connector nut, don't tighten the nut completely. You don't want the connector loose, but you do want it to be able to rotate without binding.

  • Page 30: Section 17: Elevator & Rudder Control System Installation

    SECTION 17: ELEVATOR & RUDDER CONTROL SYSTEM INSTALLATION YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT: (2) 31" Threaded Wires (2) Nylon Clevises (2) Nylon 90º Snap Keepers (2) Nylon Control Horns w/Backplates (4) 2mm x 20mm Machine Screws YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES: # 1 Phillips Head Screwdriver 5/64"...
  • Page 31 Using a modeling knife, carefully cut away all but one arm from a large "4-point" servo horn. Enlarge the third hole out from the center of the servo arm using a 5/64" diameter drill bit. Connect your radio system, plug the elevator servo into the receiver (the servo on the right side of the fuselage), then center the servo.

  • Page 32: Section 18: Aileron Control System Installation

    Install the rudder pushrod into the third hole out from the center of the servo horn. Also, don't forget to install and tighten the servo horn retaining screw. SECTION 18: AILERON CONTROL SYSTEM INSTALLATION YOU'LL NEED THE FOLLOWING PARTS FROM THE KIT: (2) Nylon Clevises (2) 4-1/2"...

  • Page 33: Section 19: Cowling Installation

    Use a couple of pieces of masking tape to hold each of the ailerons centered. Thread one adjustable control horn onto each aileron torque rod. Both control horns should be even with the tops of the torque rods, as shown in the drawing. Thread one nylon clevis onto each pushrod wire.
  • Page 34 With the cowling temporarily in place, secure the spinner backplate to the engine's crankshaft. Line up the front of the cowling using the backplate as your guide. When aligned properly, the cowl ring should be centered with the spinner backplate and there should be about a 1/16"...

    Cut out and apply the decals using the box cover photos as your guide. If any air bubbles form under the decals you can "prick" the bubbles with a straight pin to release the air. SECTION 21: BALANCING THE DRAGON LADY 60 ARF YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:...

  • Page 37: Section 22: Lateral Balancing The Dragon Lady 60 Arf

    SECTION 23: CONTROL THROWS We recommend setting up the Dragon Lady 60 ARF using the control throws listed below. These control throws are suggested for initial test-flying because they will allow the airplane to fly smoother and make it easier to control.

  • Page 38: Section 24: Preflight Check & Safety

    SECTION 24: PREFLIGHT CHECK & SAFETY Completely charge the transmitter and receiver batteries before your first day of flying. Check every bolt and every glue joint in the airplane to ensure that everything is tight and well-bonded. This should include all of the control surface hinges as well. Double-check that you've installed and tightened all of the servo horn retaining screws.

  • Page 39: Section 25: Flying The Dragon Lady 60 Arf

    IN THE AIR In the air the Dragon Lady 60 is as smooth and docile or as wild and aerobatic as you want it to be. With the control throws set to the "Test-Flying" settings, the airplane is smooth throughout the entire flight envelope. Most flyers interested in sport-flying will probably want to keep the control throws set to the "Test-Flying"...

  • Page 40: Section 26: Dragon Lady 60 Arf Trimming Chart

    SECTION 26: DRAGON LADY 60 ARF TRIMMING CHART After you have test-flown and done the initial trim changes to the airplane, use this trimming chart to begin trimming your airplane. Following and adhering to this chart will result in the ability to diagnose trim problems and correct those problems using the simple adjustments shown below.

  • Page 41: Section 27: Optional Rear-Mounted Elevator & Rudder Servos

    SECTION 27: OPTIONAL REAR-MOUNTED ELEVATOR & RUDDER SERVOS This section describes installation of the optional rear-mounted elevator and rudder servos. As stated previously, we suggest installing the elevator and rudder servos in the back of the fuselage if you will be using larger, heavier engines. This will help balance the airplane without having to add extra weight to the tail.
  • Page 42 Connect your radio system and plug the elevator servo into the receiver. Double-check that the elevator trim lever on your transmitter is centered. Attach the servo horn to the servo, making sure it's centered and points up toward the top of the fuselage. With the elevator and the servo horn centered, draw a mark on the elevator pushrod wire where it crosses the third hole out from the center of the servo horn.
