hetf16/1.jpg
01 - The F-16 as it arrives well packed from Markos at Warbirds-RC
hetf16/2.jpg
02 - The model is double boxed and all parts are wrapped for protection
hetf16/3.jpg
03 - The HET-RC F-16 Falcon ARF Minifan 480 Jet out of the box
hetf16/4.jpg
04 - The major components of the model. It is very similar to the HET-RC FA-18 in construction and covering
hetf16/5.jpg
05 - Front view of cockpit area. The glass work is very well done
hetf16/6.jpg
06 - Rear view showing pre-installed Fiberglass Intake and formers
hetf16/7.jpg
07 - Construction: Sand the wing saddle on the fuselage for good glue purchase
hetf16/8.jpg
08 - Five Minute Epoxy is applied in the wing spar hole using a cut down mixing stick to fit the slot
hetf16/9.jpg
09 - Next, insert a wing spar until it bottoms out in the slot
hetf16/10.jpg
10 - Spar shown installed
hetf16/11.jpg
11 - Clean up excess epoxy with some paper towels and denatured alcohol
hetf16/12.jpg
12 - Spar installation shown completed
hetf16/13.jpg
13 - There is a left and right wing. The side with less curve is the bottom, so mark them "left" and "right"
hetf16/14.jpg
14 - The wing is placed over the spar and adjusted so it is centered in the rear and the front of the fuselage. This will adjust the spar to the correct position. Carefully remove the wing and let the spar glue set
hetf16/15.jpg
15 - The wing shown installed and flush in the front of the fuselage shows a gap at the rear. This will be filled with Epoxy when the wing is mounted
hetf16/16.jpg
16 - A 1/8" drill bit is used to make some holes in the fuselage. This will allow the epoxy to create "rivots" inside the wing saddle for a stronger joint. Lightly sand after drilling to remove burrs
hetf16/17.jpg
17 - Fifteen minute Epoxy is applied to the wing root
hetf16/18.jpg
18 - Fifteen minute Epoxy is applied to the wing root.
hetf16/19.jpg
19 - The wing is set in place. If you fiberglassed your wing, masking tape is used to keep excess epoxy from adhering to the finished surface. Make sure the wing is centered and the bottom of the wing is flush with the root molding of the fuselage. Keeping the bottom of the wing flush with the bottom of the fuselage will insure correct incidence without any twist for the wing position.
hetf16/20.jpg
20 - Denatured alcohol is used to remove the excess epoxy
hetf16/21.jpg
21 - The front of the wing is centered and held in place with masking tape. The rear is centered and held in place with a clamp and left to set
hetf16/22.jpg
22 - The other wing saddle is sanded for better glue purchase. A small piece of 60 grit sandpaper makes quick work of it, but be careful not to oversand
hetf16/23.jpg
23 - Epoxy is applied to the spar slot with a cut back mixing stick
hetf16/24.jpg
24 - Epoxy is applied to the spar and the wing spar is installed until it bottoms out in the slot
hetf16/25.jpg
25 - Excess glue is cleaned up with denatured alcohol and a paper towel
hetf16/26.jpg
26 - Spar is installed
hetf16/27.jpg
27 - Wing is placed in position and centered in the front and back to correctly position the spar, then it is carefully removed before the epoxy sets, then the spar is drilled for rivot holes
hetf16/28.jpg
28 - Epoxy is applied to the wing root
hetf16/29.jpg
29 - Next epoxy is applied to the fuselage wing saddle and spar
hetf16/30.jpg
30 - The wing is installed on the saddle and centered. Excess epoxy is removed with denatured alcohol and a paper towel. Then tape is used to keep the front of the wing centered and the bottom of the wing flush to the fuselage root while a clamp keeps the rear centered until the epoxy sets
hetf16/31.jpg
31 - Epoxy is applied to the joint as a fillet. A toothpick is used to apply it and the tape was place on the surfaces to catch the overflow
hetf16/32.jpg
32 - The excess epoxy is wiped off and overflow lands on the tape
hetf16/33.jpg
33 - The tape is removed, revealing a clean joint. Repeat and do the same on the other side of the model
hetf16/34.jpg
34 - Wings are shown installed on the fuselage
hetf16/35.jpg
35 - Front view of wing installation shows wings with a couple of degrees on anhedral. This was due to the design of the fuselage
hetf16/36.jpg
36 - The vertical stabilizer area of the fuselage is taped off so sandpaper does not mar the finish
hetf16/37.jpg
37 - Sand the sides of the saddle with 80-100 grit sandpaper. Be very careful as to not oversand as you could cut through the glass
hetf16/38.jpg
38 - Side view shows edges sanded and ready for epoxy
hetf16/39.jpg
39 - The top outside edges were sanded so any excess glue would adhere well and form an internal fillet. While it is not necessary, the entire top of the saddle area was sanded in the pic
hetf16/40.jpg
40 - Stab area sanded. Be careful to not oversand...if you do, simply apply a coat of epoxy on the inside area of the fuselage to strengthen
hetf16/41.jpg
41 - Marks were made in order to cut two 1 1/2" long slots in the vertical stab area that are used for both cooling and the receiver antenna
hetf16/42.jpg
42 - A Dremel with a stone cutting wheel was used to open the slots
hetf16/43.jpg
43 - A hobby knife is used to clean the corners and remove large burrs
hetf16/44.jpg
44 - Some 400 grit sandpaper is used to smooth the edges inside and out
hetf16/45.jpg
45 - The two slots are shown finished. This completes the Vertical Stab pre-assembly
hetf16/46.jpg
46 - The wood pieces that are needed for Taileron assembly. Make sure you make two opposite/mirrored trays, one for the left and one for the right. The side plates are labeled S for Short and L for Long with the long side facing the front of the fuselage when installed
hetf16/47.jpg
47 - The two ends of both servo trays were lightly beveled with 400 grit so they could fit in the slots of the side plates
hetf16/48.jpg
48 - Use a ruler to mark center on the servo tray
hetf16/49.jpg
49 - Mark both trays with a center line for your servos
hetf16/50.jpg
50 - The HS65 servos are a perfect fit and were inserted in their tray to mark for drilling. The was some play in the tray, so the servo was pushed flush against the left side, then holes were drawn on both ends. It was then pushed flush to the right side and marks were made again
hetf16/51.jpg
51 - You can see the two marks made at each end. Draw a line between them for a perfect center
hetf16/52.jpg
52 - Use a punch to mark where the holes need to be made
hetf16/53.jpg
53 - Use thin CA to coat each mounting hole area on both sides of the tray. This will prevent cracking and splintering when drilled
hetf16/54.jpg
54 - The tray is lightly sanded to smooth out the CA glue area
hetf16/55.jpg
55 - You need a hobby drill smaller than the standard US 1/16" because the servo mounting screws are so small, so I found that a medium hobby push pin would work. Use a hammer and carefully drive it through the tray like a nail, being careful to keep it straight. Remove the pin and insert it in the back side of the tray to open the hole a bit
hetf16/56.jpg
56 - Photo shows the pin driven through the plate
hetf16/57.jpg
57 - Servo mounting screws are installed to "cut" threads in the wood
hetf16/58.jpg
58 - Temporarily install the servo...the screws should match up with the holes and the servo should be centered in the tray
hetf16/59.jpg
59 - Insert a tray into a side plate. Note that the thin side of the tray faces upward toward the angled side of the plate. Do not push in all the way
hetf16/60.jpg
60 - Install the other end of a tray into a plate, with the angled side of the plate facing the thin side of the tray. Be sure to use a short plate on one end and a long plate on the other end
hetf16/61.jpg
61 - Mix some 5 minute epoxy and use a toothpick to roll it into the joint at both ends
hetf16/62.jpg
62 - Squeeze the plates in place and flush
hetf16/63.jpg
63 - Remove the excess epoxy that could prevent the servos from sitting flush
hetf16/64.jpg
64 - Removing the eopxy leaves a very fine fillet
hetf16/65.jpg
65 - Square up the tray before the epoxy sets
hetf16/66.jpg
66 - Build the other tray and make sure you make two opposite "mirrored" trays
hetf16/67.jpg
67 - Once both trays are completed, add a fillet of epoxy to the rear for added strength
hetf16/68.jpg
68 - Remove the excess epoxy so a nice fillet is made
hetf16/69.jpg
69 - Servo Tray construction completed and showing fillets at rear side
hetf16/70.jpg
70 - From the top of the fuselage- The stab block and servo tray are shown near the positions where they will be installed in the fuselage. Note that the block tapers rearward and that the tray has the "Shorter" side to the rear with the thin part of the tray pointing to the top side of the fuselage
hetf16/71.jpg
71 - The position for the Horizontal Stab rods is 62mm from the rear
hetf16/72.jpg
72 - When first installed inside the fuselage, the blocks were set too far back and not centered over the mark
hetf16/73.jpg
73 - A piece of 1/32" ply was cut as a shim to make the block thicker
hetf16/74.jpg
74 - The shim is epoxied to the bottom of the block
hetf16/75.jpg
75 - With the addition of the shim, the block is inserted and the photo shows where it now would sit inside the fuselage
hetf16/76.jpg
76 - The second block shim is added using 5 minute epoxy
hetf16/77.jpg
77 - Lightly sand the edges to even out the shim with the block sides
hetf16/78.jpg
78 - A Warning...the manufacturing process left some strands of fiberglass that were sharp as needles and located where the pencil is pointing. If you have these, carefully break them off inside so you do not get cut
hetf16/79.jpg
79 - A mark is made on the outside of the fuselage at 62mm
hetf16/80.jpg
80 - A second horizontal mark is made at the center of the fuselage
hetf16/81.jpg
81 - A 1/8" Drill is used to open the holes at the crosshairs. You may want to use a small bit to make a starter hole first
hetf16/82.jpg
82 - Masking tape is used to wrap around the block so it can be removed easily later
hetf16/83.jpg
83 - The block is temporarily installed in the fuselage
hetf16/84.jpg
84 - Keeping the drill square, make a small mark on the ply inside but do not drill through
hetf16/85.jpg
85 - The drill mark is shown centered in the block
hetf16/86.jpg
86 - The other block is installed and marked the same way. Use the masking tape tab to easily remove the block once it is marked
hetf16/87.jpg
87 - A drill press is used to drill through the block and keep the hole square
hetf16/88.jpg
88 - A Hinge drilling jig can also be used to drill a square hole
hetf16/89.jpg
89 - If you do not have a drill press or hinge jig, the the hole can be carefully drilled by hand. Do a little at a time making sure the bit stays square both horizontally and vertically
hetf16/90.jpg
90 - Trial fit the Elevon Rod and use the drill to open the hole if necessary so the rod moves in and with little effort
hetf16/91.jpg
91 - Install the block in the fuselage with the angled side toward the top. Do not glue the block in place yet
hetf16/92.jpg

hetf16/93.jpg
93 - Temorarily install a Elevon rod to check the angle
hetf16/94.jpg
94 - Rod shown in correct position, perpendicular to the fuselage where it exits. Note that the fuselage is molded to include a downward angle on the rod when compared to the wing...this is normal
hetf16/95.jpg
95 - Two 1/8" wheel collars are required to retain the horizontal stabs. You may have to purchase a set as they were not in the kit
hetf16/96.jpg
96 - Apply some blue Loktite on the setscrew for the wheel collar
hetf16/97.jpg

225 - Tape is placed around the vertical stab area to keep it clean from epoxy
hetf16/226.jpg
226 - Epoxy is applied to the vertical stab inside and the fuselage area. Use only 5 minute epoxy!
hetf16/227.jpg
227 - This is the difficult part. You need to hold the fin in place while the epoxy sets...this is why you need to use 5 minute epoxy. Keep plenty of paper towels and denatured alcohol available, install the fin, squeeze in the sides, then use an alcohol soaked paper towel to clean up the excess and hold in place. Make sure the fin remains vertical. As stated, there is a lot to do, so be sure you know the steps and have it all planned ahead of time
hetf16/228.jpg
228 - Once the epoxy sets but is still soft, remove the masking tape
hetf16/229.jpg
229 - A ruler is used to scrape away any excess soft epoxy
hetf16/230.jpg
230 - If you plan on painting your model, you can use fine sandpaper to lightly sand the fin area. Skip this step if yours is pre-painted
hetf16/231.jpg

hetf16/282.jpg
282 - Work the fan past the servos
hetf16/283.jpg
283 - Insert the fan into the forward intake duct. It may seem a bit difficult at first to get it to engage the intake duct. Keeping the bottom of the exhaust duct low enabled it to slide in better
hetf16/284.jpg
284 - Pic shows duct fully seated in the intake. It will need to be trimmed to length
hetf16/285.jpg
285 - Keep the Tailcone centered and measure the difference between the mounting holes on the fuselage and the tailcone. This is how far you will need to trim the exhaust duct
hetf16/286.jpg
286 - A 1" wide strip of paper is wrapped around the exhaust tube and a mark is made at a distance from the end that you measured in the previous step
hetf16/287.jpg
