You will notice many of the parts are marked with part numbers.
  • Page 104 010A-3 OPERATION AND CARE OF THE DOORS CAUTION: NEVER ALLOW FUEL TO COME IN CONTACT WITH LEXAN. If fuel is spilled on Lexan, spray with water or cleaner immediately to lessen the chance of crazing damage. Refer to the Windshield Section. Close doors while fueling to prevent spills from running off the wing onto the door.
  • Page 105 010B-1 S-6ES COYOTE II - DOOR ASSEMBLY HYDRAULIC DOOR LIFT INSTALLATION NOTE: Wings will need to be installed to final install the Hydraulic Door Lift. Slip the Aluminum Door Doubler into the aft end of the Door Frame. Position it flush with the top of the frame.

  • Page 172 022A-1 TRAILING EDGE SPAR ASSEMBLY NOTE: Assemble both spars the same, but make a LH and RH. Select the necessary parts as shown in the parts drawing. The trailing edge spar comes with all holes pilot drilled. The final hole sizes are called out during assembly.
  • Page 180 022D-1 WING RIB ASSEMBLY & INSTALLATION NOTE: Leading Edge Wraps and Tip Skins are riveted with 1/8” Stainless Steel Flush rivets. A suitable 1/8” Dimpling Tool and Counter Sink will be required. Aircraft Spruce has an inexpensive 1/8” Pop Grip Dimpler. A corrosion protection coating is recommended between the Ribs and Rib Clips.

  • Page 193: Wing Tip Installation

    022F-1 WING TIP INSTALLATION The Wing should be covered with Aileron attached to properly install the Wing Tip. Trim the Thermo-formed wing tips to just before the material base radius. Place 2” masking tape inboard of the #40 mounting holes in the Upper & Lower Tip Skins. Mark a line inboard on the tape, aligned with each hole.

  • Page 234 024-4 Move the rudder. Inspect as in Step #8. Look over the nosewheel. Is it properly inflated? Check the steering rods. Does the nosewheel move freely when the rudder moves? Are all the control surface hinge points well lubricated and moving freely? Repeat Step #8.

    024-5 FUEL SYSTEM OPERATIONS SIGHT GAUGE The sight type fuel gauge that is standard with this model has been reported to give erroneous readings. The sight gauge can indicate full fuel when the actual fuel level can be near empty. The cause of such incorrect readings may be the result of an improper installation.
  • Page 236 024-6 Check the throttle action. There should be no sluggish response from mid range to the top end. Do not rapidly pump the throttle. This is not a motorcycle! It is an airplane with a big fly wheel, the propeller. Jockeying the throttle will only accelerate wear on the engine and make its reliability questionable.

  • Page 238 024-8 S-6ES COYOTE II OPERATIONS PRE-FLIGHT: Refer to the pre-flight section of this manual. STARTING: Refer to the engine operations section of this manual. TAXIING: Taxiing the Coyote II is easy even in a 25 mph wind. The direct linkage to the steerable nosewheel enhances the ground handling making tight turns a snap.
  • Page 239 024-9 TURNS: The Coyote II banks quite easily with a minimum of adverse yaw. Lead into turns using a little rudder. Avoid steep banks until comfortable with the ship. Due to the quick turn rate, steep 360 degrees or 720 degree turns can be disorientating.
  • Page 240 024-10 SPECIAL OPERATIONAL CONSIDERATIONS POSITION IGNITION SWITCH Up is for on, down is for off. FLIGHT MANEUVERS THAT INDUCE NEGATIVE LOAD may cause fuel leakage through the fuel vent and momentary fuel starvation due to the negative G's on the float style carburetor. Avoid low level abrupt pull-ups followed by an abrupt dive.
  • Page 241 024-11 SPECIAL SECTION ON FLAP OPERATIONS IN GENERAL The flap equipped Coyote II has a wider speed envelope but this is only realized through proper flap usage. Please take the time to become thoroughly familiar with the aircraft and procedures before attempting any maximum performances, take-offs or landings.

    024-12 TRAILERING & TOWING PRECAUTIONS When towing long distances on an open trailer remove the tail surfaces. Highway speeds and gust loads can cause undue loads on the tail group. Make certain the wings and tail components are secure and will not catch the wind underneath. Tie down the wing at the ends about 2 ft.

    024-13 MAINTENANCE COVERING: The Coyote II is covered with a 3.9 oz. per square Dacron Sailcloth. This dyed to color material will last several years if the plane is stored out of direct sunlight while not in use. Ultraviolet light is the main reason for loss of skin strength.
  • Page 244 024-14 GENERAL DESCRIPTION AND FLIGHT PROPERTIES DESCRIPTION: The Coyote II is a high wing, tractor, mono plane with tricycle landing gear. It is strut braced with aluminum tubing and welded 4130 steel construction. It has Dacron sailcloth pull on covers. The design features a roll cage construction, an enclosed cabin when side doors are installed, shock absorbing Tapered Steel type gear, steerable nosewheel, ailerons, and flaps.
  • Page 245 024-15 KEEPING YOUR 2-CYCLE ROTAX ENGINE CARBON FREE The Rotax manual as well as the following information outlines some excellent procedures to assure reliable operations. However, in the real world the method suggested for carbon removal is only a half-way measure. True removing the cylinder heads and scraping the dome and piston top will prevent carbon from fouling the plugs.

  • Page 247 The tachometer supplied with your RANS kit is equipped with a calibration knob; refer to the manufacturer’s instructions. Once satisfied with the tachometer, run the engine with the throttle fully open; be certain the tail is tied down and the main gear is chocked.
  • Page 248 FAA certification, the fruit of which is fleets of identical aircraft for which specific checklists, procedures and performance figures may be published. This section includes much information on the operation, limitations, and performance of RANS aircraft; however, the nature of kit-built aircraft makes it impossible to publish specific checklists and procedures applicable to all examples of a particular model.
