What you will do is learn how to build your airplane the right way.
  • Page 23 Much elbow grease is saved if you replace the sandpaper often. Long Straightedge ..This is not absolutely required, but is quite handy when jigging or checking the straightness of flying surfaces. It is merely a 6-ft or 8-ft lx3 or lx4 piece of lumber that is hand-selected to be "eyeball straight".

  • Page 26 ..The variable voltage control can be obtained from Aircraft Spruce and Specialty or Wicks Aircraft Supply, or you can substitute any controllable power supply to include the 14 to 20 volt range with at least 4 amp capability. An alternative is to borrow two 12-V battery chargers or auto batteries and lash up the following device.
  • Page 27 ..The materials, processes, and terminology used in the construction of your Q2 are recent to homebuilding. This section is devoted to familiarizing you with the language, materials, and techniques used in these plans. This information is basic to the construction of your airplane.
  • Page 28 Even fewer are suitable for the hand layup techniques used in the Q2. The glass cloth used in the Q2 has been specifically selected for the optimum combination of workability, strength, and weight..The glass cloth in your Q2 carries primary loads, and its correct application is of vital importance.
  • Page 29 CONTINUED ON NEXT PAGE...
  • Page 30 ..Marking and cutting the plies of glass cloth is a job that you will repeat often in the construction of your Q2. Glass cloth should be marked, cut, and stored in a clean area with clean hands and clean tools.
  • Page 31 "aluminum" is a general term for a whole family of specialized metal alloys. Just as the "aluminum" pots and pans in your kitchen, the "epoxy" in your Q2 is vastly different from the hardware store variety.
  • Page 32 The epoxies are not similar to the common types normally marketed for fiberglass laminating. Two different systems are used in the Q2: a normal curing system, and a 5-minute system. The very fast curing (5-min.) system is used much like clecos are used in sheet metal construction (or clamps in woodwork);...
  • Page 33 ..The working and strength characteristics of an epoxy system are dependent on the resin, the hardener, and on the amount of each in a given mixture. Epoxy systems are engineered for a specific ratio of resin and hardener. It is quite important that the proper mixture be obtained.
  • Page 34 Do not mix with a brush. The bristles can soak up the hardener, changing the ratio. Use a tongue depressor or wood stick..The working temperature has a substantial effect on the pot life and cure time. Very hot conditions will cause the cure to speed up. In cold working conditions the cure will be delayed and if it is cold enough, epoxy may not cure at all.
  • Page 35 obtained. Use micro only as specifically shown - never use micro between glass layers..Always use the following method to join foam blocks. This is extremely important. Check that the foam blocks fit closely together. If there are voids over 1/16 inch, sand to fit, or fill the void with a sliver of foam.
  • Page 36 Q2 Plans - Chapter 3 - Page 3-05 FLOX ..Flox is a mixture of cotton fiber (flocked cotton) and epoxy. The mixture is used in structural joints and in areas where a very hard, durable buildup is required. Flox is mixed much the same as dry micro, but only about two parts flock to one part epoxy is required.
  • Page 37 works up to a point where so much hardener is added that the mixture never hardens. Follow the general directions on the Bondo can for fast setting Bondo. Mixing is done on a scrap piece of cardboard or plywood (or almost anything), using a hard squeegee or putty knife. A blob of Bondo is scooped out of the can and dropped on the mixing board.

  • Page 39 CONSTRUCTION TECHNIQUES HOT WIRE CUTTING ..The airfoil-shaped surfaces of your Q2 are formed by hot wire cutting the orange or blue-white styrofoam of 2 lb/ft3 density. The hot wire process given airfoils that are true to contour, tapered, properly twisted, and swept with a minimum of effort and the simplest of tools.
  • Page 40 Templates are made from thin plywood, sheet metal, masonite or Formica. A variable voltage control is used to supply the electrical current that heats the wire..The blue-white or orange foam used in your flying surfaces was selected for a combination of reasons and its hot wire cutting ability was one of them.
  • Page 41 pausing on the tab, wire's out." As the cut is made, the person on the small rib follows the numbers, passing over them as he hears them called out. Pause marks are indicated in places where it is necessary to pause for a couple of seconds and let the hot wire's center lag catch up with the ends.
  • Page 42 templates should be a close fit for the nails. Be careful not to angle the nails so that the hot wire can catch on them! Some rib templates are used several times, for both inboard and outboard, requiring you to transfer the talking numbers, pause marks, trim line, and waterline to the opposite side of the template.
  • Page 43 Q2 Plans - Chapter 3 - Page 3-07 ..The use of the hot wire saw is a simple thing if your equipment is set up properly. Proper wire tension and wire temperature should be maintained for good cutting. The wire tension should be tightened after the wire is hot by twisting one tube with a pair of pliers.
  • Page 44 ..The hot wire should be guided around the templates with light pressures. Pushing too hard against the template may move them or flex the foam block which results in an under cut foam core..The correct set-up is just as important as using the correct tools and materials.
  • Page 45 Use a dust respirator mask while carving urethane. Try not to aggravate the better half by leaving a green foam dust trail into the house. PAGE 3-7 Q2 Plans - Chapter 3 - Page 3-08...
  • Page 46 GLASS LAYUP ..The glass layup techniques used in your Q2 have been specifically developed to minimize the difficulty that glass workers have traditionally endured. The layups that you will do will be on a flat horizontal surface without the molds, vacuum bags, and other special equipment that are common in glass work.
  • Page 47 part - be sure your core looks exactly like that on the section view. Lay a 12 inch straightedge spanwise on all critical areas of the flying surfaces and be sure you don't have any high or low places or joggles.
  • Page 48 wet and the excess resin brought up by squeegeeing to help wet out the middle plies. To do this, pour epoxy onto the part and move it around the surface with a squeegee. Your work will go much faster if you make the layup too wet, then remove excess epoxy with many light passes with the squeegee.
  • Page 49 epoxy is much better on the floor than on the airplane. It is possible to squeegee too hard and make the layup too dry. If this occurs, the surface will appear white, indicating the presence of air. If this occurs, wet the cloth by painting on a little epoxy and stippling it down into the layup.
  • Page 50 around a sharp corner. STEP 9: PRELIMINARY CONTOUR FILL ..Certain areas, like along the trailing edge (see cross section views) require a dry micro fill. It is preferred to apply this fill within 2-3 hours of finishing the fiberglass layup. However, where the micro filler obscures the structure underneath, FAA inspection should be completed before dry micro filling.
  • Page 51 Wood requires no special preparation for bonding but should be free of grease, oil, paints, and varnish. Sand wood surfaces with 36-grit sandpaper before layup. Metal bonding is not relied upon for strength but PAGE 3-9 Q2 Plans - Chapter 3 - Page 3-10...
  • Page 52 metal surfaces should be free of oil and grease and, except for bolts, nuts, and other fasteners, metal surfaces should be dulled by sanding with 220-grit sandpaper, and coated with epoxy before setting in place. Cured micro surfaces should be sanded dull but be careful not to obliterate surrounding foam surfaces while doing it.
  • Page 53 ..The Dremel (Moto Tool) or Home Shop (Weller) is a very versatile tool with many uses in the construction of your Q2. The kits usually have a nice selection of bits, cutters, grinders, stones, and mandrels for every conceivable use.
  • Page 54 A pneumatic riveter is not required. The few hard rivets used can be set with a hammer, using your vise as backup. The 'pop-type' rivets are pulled with a low-cost hand puller available at any hardware store. Q2 Plans - Chapter 3 - Page 3-11...
  • Page 55 CUTTING THE UNI SPAR CAPS ..The spar caps used in the main wing, vertical tail, and canard, are strips of UNI cloth that you will cut from the roll provided in the kit. Begin by unrolling the roll on a long, flat surface. The example to be used here will be a spar cap A that is 8"...
  • Page 56 TAPES ..Quite often during the construction of your Q2, you will be asked to use glass tapes to join two pieces together..A glass tape is a strip of BID cut at 45 degrees which is used to lap up onto both surfaces that are being joined.
  • Page 57 construction technique is your ability to visually inspect the structure from the outside. The transparency of the glass/epoxy material enables you to see all the way through the skins and even through the spar caps. Defects in the layup take four basic forms: resin lean areas, delaminations, wrinkles or bumps in the fibers, and damage due to sanding structure away in finishing.
  • Page 58 Q2 Plans - Chapter 3 - Page 3-12 ..The following is a listing of the "critical areas"; the portions of the Q2 that must meet all the inspection criteria: 1. Entire canard. 2. All portions of the fuselage within 10" of the engine mounts, canard, and wing.
  • Page 59 4. All flying surfaces in the shaded areas shown, plus all overlaps at L.E. & T.E..Major wrinkles or bumps along more than 2" of chord are cause for rejection in the wings, canard and vertical fin, particularly on the top (compression side).
  • Page 60 CORNER TREATMENTS ..A variety of structural corners are employed in the construction..There are two basic types of corners: one where the glass fibers are continuous around the corner, and the other where a structural filler is used and glass is bonded to the filler. The corner with the glass fibers running completely around it is used where maximum strength is required.
  • Page 61 ..Outside corners require a radiused edge. Where the glass fibers run directly around the corner a minimum radius of 3/16 inch is required. Where the fibers run at an angle to the radius, only a 1/8 inch radius is needed. CONTINUED ON NEXT PAGE PAGE 3-12...
  • Page 62 Q2 Plans - Chapter 3 - Page 3-13 ..In some areas a sharp corner is desirable and maximum strength isn't required. In these areas a flox corner is used. A simple unsupported glass corner has very poor strength. To strengthen this corner, a triangle of flox is used to bond the glass plies together.
  • Page 63 SKIN PROTECTION ..If you work with epoxy on your bare skin, you can develop an allergy to it. This "sensitization" to epoxy is an unpleasant experience and is to be avoided. You generally have to get epoxy on your unprotected skin to become sensitized. If you use a protective barrier skin cream like Ply No.9, or disposable plastic medical examination gloves, the allergy can be avoided.
  • Page 64 ..Using these three references, any point in an airplane can be described with a fuselage station, butt line, and waterline. Fortunately, your Q2 is so simple that we don't need to locate very many things this way. When you start on your 4/5 scale replica of a B-1 Bomber, this reference system will be real handy.
  • Page 65 Proper techniques must be adhered to for safety as well as to obtain an attractive airplane..The Q2 is sensitive to weight growth. You may easily add 50 pounds during the finishing process if you try to finish the entire aircraft to sailplane standards (smooth, wave-free surfaces).
  • Page 66 White has been chosen as the standard color for fiberglass sailplanes to preclude any possibility of excess temperature due to solar heating. The same criteria apply to the Q2, and white is recommended. Trim colors in less-critical areas such as the fuselage, vertical tail, and the underside of wings and canard, can be other than white.
  • Page 67 TOOLS AND MATERIALS ..The tools and materials used in finishing the composite airplane are simple and straight forward. A low density microsphere/epoxy mixture (dry micro) is used for coarse filling requirements. Automotive type polyester body fillers (Bondo) are very heavy and not recommended as a primary aircraft finishing material.
  • Page 68 Q2 Plans - Chapter 3 - Page 3-15 ..The sanding spline is a finishing tool common to the sailplane industry. It is an easy tool to make and does an excellent job of contouring. You may find it handy to make two, one for coarse grit sandpaper and one for medium or fine sanding.
  • Page 69 THE FINISHING PROCESS ..Finishing the composite airplane is a five-step operation. Repairs or rework of structure must be completed first, before the obscuring finish is applied, and final structural inspections must be complete. Second, coarse contour filling is done with microspheres/mixed with epoxy (dry micro) as required in areas requiring .03 inch to .20 inch of fill.
  • Page 70 CONTINUED ON NEXT PAGE PAGE 3-15 Q2 Plans - Chapter 3 - Page 3-16...
  • Page 73 STEP TWO: COARSE FILLING ..You must be extra cautious in this step or you may destroy your structure. When you take a piece of sandpaper and start grinding on your composite structure it's like using acid to clean a metal wing spar.
  • Page 74 CONTINUED ON NEXT PAGE PAGE 3-16 Q2 Plans - Chapter 3 - Page 3-17...
  • Page 75 ..Paint a thin coat of epoxy over the area to be filled. Dry micro is then lumped over the area. The fill must be high, such that material is sanded away to bring the area into contour. The micro should be mixed very dry (lots of microspheres) to save weight. Let the micro cure at least 24 hours.
  • Page 76 block in preparation for feather fill. A spray or brush coat of feather fill will build up .02" to .03" thick, fill the glass weave and any medium sized out-of-contour spots. Feather fill will require several hours curing time before it can be sanded. The cured feather fill is sanded to contour using a spline or soft block and 100-grit sandpaper.
  • Page 77 Automotive trunk paint may also be used. Its “speckled" appearance will hide the weave of the glass cloth. PAGE 3-17 Q2 Plans - Chapter 3 - Page 3-18...
  • Page 78 If you have a gap of more than .005 inch, your surface is too wavy. Check this in several places from the leading edge back to 50% chord. The bad Quickie wing had gaps of about .012 inch. After refinishing with gaps of less than .005 inch, its stall angle of attack increased from 8 deg.
  • Page 79 ..The materials, methods, and practices employed by the amateur builder in the construction of the Q2 type are new to light aircraft construction and may be unfamiliar to the inspection personnel involved with the licensing of amateur built aircraft. Structural design criteria for the Q2 exceed F.A.R.
  • Page 80 5% of the laminate surface area. Voids greater than 2 inches in diameter should be repaired as shown in paragraph 4. CONTINUED ON NEXT PAGE PAGE 3-20 Q2 Plans - Chapter 3 - Page 3-19...
  • Page 81 3.2 LEAN AREAS ..Areas where the epoxy/glass matrix is incomplete because of inadequate wetting of the cloth with epoxy (lean areas) are speckled whitish in appearance. The fully wetted laminate will have a consistent transparent greenish appearance. Epoxy lean areas are acceptable, as long as the white speckled area is less than 10% of the surface area.
  • Page 82 4.0 REPAIRS ..There are seldom single defects so massive that a major component must be scrapped. The repair procedures described here may be applied throughout the QUICKIE and Q2 composite sandwich structures. 4.1 SMALL VOID REPAIRS ..Voids up to 2 inches in diameter may be repaired by drilling a small hole into the void and injecting the void full of epoxy.
  • Page 83 QUICKIE and Q2 structures. Design safety factors in excess of three enable somewhat relaxed acceptability criteria compared to other similar structures. PAGE 3-20 Q2 Plans - Chapter 3 - Page 3-20...
  • Page 84 1/2 ounce layup has too much resin, and if you make all of the 1ayups in the airplane this wet, your Q2 may be as much as 50 pounds over weight. An 11 ounce layup is just about perfect. Save this piece; it will be useful to check future 1ayups against.
  • Page 85 This layup is a sample of composite sandwich structure and is typical of the load carrying structures in your Q2. When this layup is finished, and completely cured, you will subject it to a simple load test, and thus demonstrate the strength of your workmanship.
  • Page 86 ..Now for the test: lay a broom handle or piece of tubing on the work bench and try to break the sample by putting all of your weight on the ends. A 200 pounder will stress the sample more than any part of your airplane is stressed at 10 g's.
  • Page 87 Q2 Plans - Chapter 3 - Page 3-21 BOOK END ..The last practice part that you will make before starting on your airplane is a book end. It takes three layups to make the book end and involves most of the operations that you will need to learn, to build your airplane.

  • Page 90 ..Mix Safe-T-Pox, make a small batch of slurry, and save the remaining epoxy. Slurry the foam surface and apply two plies of BID to the contoured surface. Start the layup in the center and work out toward the edges. If you have trouble getting the glass into the depression corners without bubbles, lift the plies and wipe in a little dry micro.
  • Page 91 ..Wait until the second layup is fully cured. Remove the 1 inch foam block with a butcher knife and sanding block. Remove foam for a 1/4" flox corner and sand the glass surface dull.
  • Page 92 ..Mix Safe-T-Pox, a small batch of flox, and a small batch of micro slurry. Fill the corner with flox and slurry the foam. Lay up the four UNI plies with the orientation shown.

  • Page 94 CLOTH CUTTING : You-can get by with just a standard pair of good fabric scissors, but the job is much easier with the large pair of industrial scissors (Weiss model 20W). They're $25 (gulp!) but worth it in the long run. SURFACE PREPARATION: FOAM - Hot-wire-cut surface needs no preparation.
  • Page 95 Wet Micro - Enough microspheres for a "thick honey" mix. Dry Micro - Enough Micro so it won't run. Wet Flox - Thick, but pourable mixture of epoxy and flocked cotton. APPLY TO SURFACE: Layup Over Foam - Brush or squeegee on a thin micro slurry layer (thick over urethane).
  • Page 96 PRELIMINARY CONTOUR FILL : Save sanding by troweling dry micro over low areas while the glass layup is still tacky. This is done at trailing edges, spar caps, or 'over any low areas. The low places are overfilled with micro then sanded smooth after full cure.

  • Page 108 section. The reason for this is to obtain the proper sweep of the canard when the cores are jigged together later..Begin by squaring up the 10" x 20" X 96" nominal dimension block of polystyrene foam to obtain a length of 51.2", with the skew as indicated. Next, using the sketch provided, hot-wire the outboard canard foam cores.
  • Page 109 CONTINUED ON NEXT PAGE PAGE 5-2 Q2 Plans - Chapter 5 - Page 5-03 ..Finally, locate the remaining part of the 10" x 20" block and size it as shown, in order to make the canard center section. Keep the unused portion for cutting the vertical fin, so don1t make the height over 6.0".

  • Page 265 ENGINE BAFFLING ..The purpose of the engine baffling is to provide adequate airflow for cooling to all critical areas of the engine and accessories. Air enters through the cowling air inlets located on either side of the spinner. A vertical baffle located in front of the forward engine cylinders forces the incoming air to travel upward across the cylinders and then down through the fins, exiting the bottom of the cowling through the variable opening cowl flap.
  • Page 267: Fuel System Installation

    FUEL SYSTEM INSTALLATION INTRODUCTION ..The Q2 fuel system consists of a main fuel tank that forms part of the seat, and a fuel header tank positioned above the passengers' legs. The carburetor receives fuel by gravity feed from the header tank.
  • Page 268 FUEL FILLER SYSTEM ..Provided with your Q2 kit is a small storage bottle. By cutting the ,neck from this bottle, the upper part can be used as the fuel cap. The storage bottle top is compatible with fiberglass/epoxy laminates.
  • Page 269 HEADER TANK CONSTRUCTION ..Previously, in Chapter 14, you have installed the main fuel tank permanently in the fuselage, along with the main fuel tank fuel gauge..The important fuel header tank dimensions are shown in the accompanying drawings. This fuel header tank is installed against the upper fuselage inside skin approximately 5 inches aft of the firewall.
  • Page 270 One BID on either side of the foam is used when assembling the header tank. The laminations that will 'see' gasoline, should be made slightly wet to minimize leakage. PAGE 17-1 Q2 Plans – Chapter 17 – Page 17-02...
  • Page 271 HEADER TANK PLUMBING ..Prior to permanent installation inside the fuselage, the plumbing for the header tank should be installed. The accompanying drawing shows the location for all header tank plumbing. The fuel feed to the engine should be patterned after the main fuel tank feed shown on Page 14-3, including the screen and flox, but omitting the drain valve.

  • Page 282: Completing Your Q2

    COMPLETING YOUR Q2 STREAMLINING YOUR Q2 ..A significant improvement in your Q2's aerodynamic cleanliness can be achieved by fabricating fillets and fairings for the major component intersections. A bit of artistic ability is necessary to develop a pleasing and efficient shape, but at this stage of the construction, you will be up to it.
  • Page 283 ..A fillet is also necessary between the inboard face of the wheel pant and the outboard end of the elevator. Set the elevator with the trailing edge approximately 4 degrees up. Use scrap foam and 1 BID to create a fillet similar to the one shown in the picture. ELEVATOR INBOARD FILLETS ..
  • Page 285 PAGE 20-1 Q2 Plans - Chapter 20 - Page 20-02 CANARD/FUSELAGE FAIRING ..At this point, their should be a noticeable and ugly gap under the fuselage where the canard and fuselage meet. A fairing should be made out of scrap foam and 1 BID similar to the picture.
  • Page 287 MAIN WING TIPS ..Now would also be a good time to carve wing tips on the main wing. If you wish, you may add up to 3 inches of foam to the wing span to facilitate a smooth looking wingtip. Keep it simple, however. VERTICAL FIN TIP ..
  • Page 289 PAGE 20-2 Q2 Plans - Chapter 20 - Page 20-03 CARBURETOR AIR INLET ..Cut a round hole in the lower cowling for the carburetor air inlet. Fabricate a round tube by laminating 4 BID around a bottle such that the tube will slip over the end of the alternate air source.
  • Page 290 CANOPY RETENTION ..It is advisable to have some form of restraint for an open canopy besides permitting it to rest on the main wing. Otherwise, in case of a strong wind, the canopy may be blown off of the aircraft..The illustration shows a simple shock cord arrangement.
  • Page 291 COCKPIT AIR VENTS ..A cockpit air vent on either side of the fuselage must be installed prior to first flight. A simple shape, and recommended location, is shown in the sketches..To exhaust the cockpit air, a hole could be cut in the tailcone, or else an exhaust vent could be cut in the aft top fuselage.
  • Page 292 PITCH TRIM SYSTEM TENSION ..While writing Section II of these plans, and building N81QA, we built a simple system to vary the tension, or drag, on the pitch trim wheel..Make a third TS-1 bearing from phenolic. Drill a 3/8" diameter hole as shown.
  • Page 293 Q2 Plans - Chapter 20 - Page 20-04 EXHAUST SYSTEM MOUNTING ..The exhaust pipe exits the cowling next to the cowl flap. In traveling from the cylinders to the exit, the exhaust system will enter and exit the baffling. These holes must be closed up to prevent air leaks, and consequent reduction in cooling.
