40 - 46 Size Almost Ready to Fly
Instructions for Final Assembly
Commemorate the Aviation's beginnings with the new Global Blue Max ARF. A time when the nose skid was as important as the tail skid to safety minded pilots landing on unprepared airfields, planes of this style used cutting edge technology for their day. The Blue Max remembers those years long past. It's open cockpit, wire spoke wheels and open framework capture a more experi­mental time in aviation. The high lift wing and generous wing area mean super slow stall speed and very forgiving flight characteristics. Don't be sur­prised if you see beginners with this plane. Our test pilots say this plane is easier to fly than most .40 size trainer planes. And unlike the grossly under­powered airplanes of yesteryear, the Blue Max is favorably powered using a .40 size two stroke or a .52 size four stroke. So put on your scarf and your goggles and get ready to go back into time. Oh, and don't forget to load that cannon!

**SUGGESTION** To avoid scratching your new airplane, do not unwrap the pieces until they are
needed for assembly . Cover your workbench with an old towel or brown paper , both to protect the aircraft and to protect the table. Keep a couple of jars or bowls handy to hold the small parts after you open the bags.
**NOTE** Please trial fit all the parts. Make sure you have the correct parts and that they fit and are aligned properly before gluing! This will assure proper assembly . Since the Blue Max is hand made from natural materials, every plane is unique and minor adjustments may have to be made. However, you should find the fit superior and assembly simple.
WING ASSEMBLY
PARTS REQUIRED
o {2} Wing Halves w/Ailerons and Hinges o {1 } Forward Dihedral Brace (W-40) o {1 } Rear Dihedral Brace (W-41)
INST ALL THE DIHEDRAL BRACES
o 1) Look at the face of each root rib on both wing halves. Notice how the excess covering ma­terial overlaps onto them. Using a modeling knife, carefully cut away the covering from both of the root ribs. Leave about 1/16” of covering over­lapping so it does not pull away .
It is important that the covering be removed
from the root ribs. This will ensure an ad­equate wood-to-wood glue joint and prevent wing failure during flight.
o 2) Using a ruler and a pen, locate and mark the center section of the forward and rear dihe­dral braces (W-40 and W-41). Draw a vertical line at this location on both braces. See photo
# 1 below .

o 3) T est fit the dihedral braces into their re­spective boxes in each wing half. W-40 fits into the forward box and W-41 fits into the rear box. The braces should slide into each wing half up to the centerlines. If they do not, remove them and lightly sand the edges and tip of each one until the proper fit is obtained. See photo # 2 below .

The dihedral braces are cut in the shape of
a "V". They should be installed with the "V" shape facing upright to form the proper dihedral angle when the wings are joined.
o 4) T est fit both of the wing halves together with the dihedral braces temporarily installed. Do not glue them in at this time! The wing halves should fit together tightly with little or no gaps in the center section joint. If the center section joint is not tight, remove the wing halves and lightly sand the edges and tips of each brace. Reinstall the wing halves and braces and test the fit until you are satisfied that the center section joint is tight.

JOINING THE WING HAL VES
o 6) Mix a generous amount of Kwik Bond 30 Minute Epoxy . W orking with only one wing half for now , apply a thin layer of epoxy inside both dihedral brace boxes and on only half of each dihedral brace. Make sure to cover the top and bottom as well as the sides and use enough epoxy to fill any gaps.
WING MOUNTING
PARTS REQUIRED
o {1 } Fuselage o { 2 } Wing Hold Down Dowels (W-43) o {2} Wing Struts o {6 } 3mm x 10mm Machine Screws o {6 } 3mm Flat Washers
INSTALL THE WING HOLD DOWN DOWELS
o 7) Slide the dihedral braces into the boxes up to the centerlines. Remove any excess epoxy before it dries using a paper towel and rubbing alcohol. Allow the epoxy to cure before pro­ceeding. See photo # 3 below.
Photo # 3
o 8) Once the epoxy has cured, trial fit both wing halves together to double check that the wing halves still fit correctly .
o 9) Mix a generous amount of Kwik Bond 30 Minute Epoxy . Apply a thin layer of epoxy to the exposed halves of both dihedral braces, the inside of both dihedral brace boxes i n the second wing half and the entire surface of both root ribs. Make sure to use enough epoxy to fill any gaps.
o 1) Using a modeling knife, carefully remove the covering from over the four predrilled holes in the fuselage sides. T wo holes are located on each side of the fuselage. See photo # 5 below .

o 8) Place the wing into the wing saddle. Align the centerline of the wing at both the leading and trailing edges with the two marks you made on the fuselage.
These two marks will help you align the wing
when you install it on the fuselage. Y ou may wish to make these marks in permanent ink so you can align the wing correctly each time you install the wing. This will ensure the wing is aligned properly each time you fly the airplane.
INST ALL THE WING STRUTS
o 6) There are two preinstalled blind nuts that are used to mount the wing struts to the bottom of the fuselage. Using a modeling knife, care­fully remove the covering from over the two blind nut holes on the bottom of the fuselage. The holes are located 1/2” in from the fuselage sides and 8-1/4” back from the front of the firewall.
See photo # 8 below .

o 9) Using a couple of # 64 rubber bands, temporarily secure the wing in place making sure it is aligned. T o correctly install the rubber bands, hook one over one of the front wing hold down dowels, carefully pull it back over the top of the wing and hook it over the rear hold down dowel on the same side. Install two rubber bands on each side for now .
o 10) Bolt the wing struts to the wing and to the fuselage using the six 3mm x 6mm machine screws and six 3mm flat washers. It may be necessary to move the wing slightly to properly align the holes in the struts with the blind nuts.

The rear blind nut is 2-3/4” forward of the trailing edge and the front blind nut is 3” back from the leading edge. Using a modeling knife, carefully remove the covering from over the two blind nut holes in each wing half. See photo # 9 at top right.
HORIZONTAL STABILIZER
MOUNTING
PARTS REQUIRED
o {1} Horizontal Stabilizer w/Elevator and Hinges
ALIGN THE HORIZONT AL STABILIZER
o 1) Remove the elevator from the horizontal stabilizer and set it aside for now . Turn the stabi­lizer upside down on your work surface. The bot­tom side is the flat side and should be facing up.

o 6) With the stabilizer held firmly in place, use a pen and draw a line on the stabilizer where it and the fuselage sides meet. Do this on both the right and le ft sides on the bottom of the stabilizer.
o 7) Remove the stabilizer. Using the lines you just drew as a guide, carefully remove the covering from between them, using a modeling knife. See
photo # 13 below.
o 4) Attach the wing to the fuselage and re­move both ailerons. Set the horizontal stabilizer onto the stabilizer mounting platform on the fuse­lage. Align the centerline marks on top of the stabilizer with the centerline marks at the front and rear of the stabilizer mounting platform. When the marks are aligned hold the stabilizer in posi­tion using a couple of T-pins. Align the horizontal stabilizer with the wing. When viewed from the rear, the horizontal stabilizer should be level with the wing. If it is not level, use sandpaper and sand down the high side of the stabilizer mount­ing platform until the proper alignment is achieved. The tips of the stabilizer should also be equal dis­tance from the tips of the wing. See figures # 1
and # 2 at top right.

COVERING
When cutting through the covering to re-
move it, cut with only enough pressure to only cut through the covering itself. Cutting into the balsa structure may weaken it and cause pos­sible failure in flight.

o 8) When you are satisfied that everything is aligned correctly , mix up a generous amount of Kwik Bond 30 Minute Epoxy . Apply a thin layer to the bottom of the stabilizer mounting area and to the top of the stabilizer mounting platform on the fuselage. Set the stabilizer in place and re­align. Double check all of your measurements once more before the epoxy cures. Hold the sta­bilizer in place with T-pins or masking tape and remove any excess epoxy using paper towels and rubbing alcohol.
o 4) Set the vertical stabilizer back in place. Using a triangle, check to ensure that the vertical stabilizer is aligned 90º to the horizontal stabilizer .
See figure # 3 below .

PARTS REQUIRED
o {1} V ertical Stabilizer w/Rudder and Hinges
ALIGN THE VERTICAL ST ABILIZER
o 1) Remove the rudder from the stabilizer . Slide the stabilizer into the slot in the top of the horizontal stabilizer . The rear edge of the vertical stabilizer should be even with the rear edge of the horizontal stabilizer and fuselage. It should also be pushed down completely into the slot.
o 2) Using a pen, draw a line on each side of the vertical stabilizer where it meets the top of the slot on the horizontal stabilizer.
o 3) Remove the stabilizer. Using a modeling knife, remove the covering from just below the lines you drew . Also remove the covering from the bot­tom edge of the stabilizer. See photo # 14 below .

COVERING
When cutting through the covering to re-
move it, cut with only enough pressure to only cut through the covering itself. Cutting into the balsa structure may weaken it. There may also be covering material overlapped on the in­side edges of the vertical stabilizer mounting slot in the horizontal stabilizer . Using a modeling knife, carefully remove this covering also. This will help insure a good glue joint.
HINGE THE AILERONS
o 1) The C/A hinges have already been glued into the two ailerons. W orking with one aileron at a time, slide the aileron and it's hinges into their precut hinge slots in the trailing edge of the wing, making sure the torque rod is firmly seated in the precut hole in the leading edge of the aileron. Slide the aileron in until it is tight against the trailing edge of the wing. The maximum hinge gap should be no more than 1/32” and the tip of the aileron should be flush with the tip of the wing.
