First glance at the box
After seeing the Canopy and Aft Fuselage... you can see it's BIG!
The obligatory *slap together*
Size against a .60 sized Mustang!
I am feeling Blue
If you look close, you can see the Spar stick out a little on the left and the dark part of the wing is the Spar. Goes all the way into the wing tip tank
Spar on the Horizontal tail
Mandatory parts layout
You can see part of the spar in the Wheel Well
Wood parts and hard Ware included in the kit
Wing with four wood spars (two double spars)
Bottom of the forward fuselage.
Same but different view just in case you missed it on the first Pic :)
Intakes themselves are large enough
Cut out the rudder and Filled in the stab tip before I cut out the elevator.
Here is what I mean by filling in the Tip
Cut out the elevator
i am gluing the landing gear mounts together, you have to make 6 of the double wood parts
Main gear with four landing gear mounts.
the two forward fuselage formers and one set of landing gear mounts
There are only two formers required in the nose before you can glue it together but for visual, I included one landing gear mount and also note the former at the right of the picture
I wanted both elevator servos facing the same direction to avoid using another channel or a servo reverser
New servo pocket cut out and partiallied filled in the old one
servo wires route the middle of the Horizontal stab and go up to the tail to a tunnel
Both elevetaor wires routed to the tunnel
Here is the other side where the Vertical stab will glue in and the lower part of that tunnel will serve as a route for the servos wires
Rudder hinged and tunnel cut out for the servo wire. I will later fill this in with spacke and the wire should not be visible.
Two main wing spar joiners, Glue two pieces together to make two spars out of the four pieces. I also glued to Rocket Pod Launcher while I had the Glue at hand.
parts needed to make the wing one piece
three pieces go in the top of the wing. the Two wing spars and the forward wing hold down. One of the spars from this picture has been changed, Please see the last Picture
Fitted flush as they should be glue
The bottom part of the wing gets the two wing mounting screw supports.
Servo packet/tunnel between the Vertical and horizontal stab
Notice how the front spar is like a U shaped. This is the correct forward spar for this wing.
Formers/wood pieces needed for the rear Fuselage
Vuew of them in the fuselage
There are pockets / guides on the fuselage where all the pieces go, elminating any guess work or measuring.
parts needed for the wing landing gear mounts
Glue to brackets on each side
place the metal retainer on top of the brackets
Screw in your landing gear.
Light set from RC lander, I ordered another set from EJF because I need a landing light on each Tip Tank. Spackle to fill in where needed
Testing the lights first
Everything is now glued in.
Spackle to hide the holes/tunnels made
Splitter Plate, I sanded the forward edge so that it would be a little sharp you can see the dark area in the front.
Splitter plate now glued on intake wall.
I filled in where the old servo pocket used to be at
Some more filling, I filled in the pockets where the control horn protudes in the tail of the plane. You can also see the Flap cut off from the wing.
Hard to see, but you you look close to the Light Controller, on the right hand side wires, I peeled the wires back and here I am testing the Two landing lights. They light up, no problem.
See the big stump? About the size of a U.S. Quarter (.25C) Coin
Typical Fly-Fly and now Hobby Top Gun panel lines. Don't take me wrong, I like them but they are a little on the larger side.
If you look at the vertical stab, you can see clearly where it was glued to the fuselage and not filled in, BIG panel/joint line.
Filler drying on the rear fuse (top) Forward fuse has already been sanded.
If you look at the fuse glue joint in where the vertical would go, that's how the seam would look all the way around the plane. In the forward part, it is filled and drying.
You can see where the seam used to be (darker area) and where the panel lines where on the nose.
All done with the Fuse and tail.
Water based Poly Urethane
you can see it applied here, it made the stab look yellow, like if I would have used epoxy. Anyway, One coat, then tomorrow sand with 220 then add second coat. then paint.
Only tools I used, Allen driver and exacto
Puncha a hole in the center of the tank at least two inches deep
Then punch a second hole at an agle. I am routing the wire to the side intentionally in case of a gear up landing or if the tank scrapes, the wire does not risk getting cut
Pull the wire through
It sticsk out like a soar thumb.
I used the exacto to cut a pocket for the light to fit into
One Landing light all done
with the Landing light done, we can now move on the the other light
again I used the TLAR method to figure out where the light should go. About half way looks about right
I punch the hole with a pushrod this time
Pull the cable through. (I removed the end Receiver connector to only hava a small hole)
with all tha work done, did I pull the wires or make the lights not work? Nope all is well, you want to try them out before you seal the wires in.
Rule to show Usable space.
XPS 3S1P 4000 X2 laying on top of each other
XPS 3S1P 4000 standing up
Blue Lipo 4S 4000 Standing up
4S1P one standing one laying on side.
Fly Fly twin 90mm MiG-29 Fully glassed, weave filled with microballoon/WBPU paste, sanded, sealed with WBPU, painted then top-coated with WBPU.
Starmax 90mm F-18 Not glassed, Just filled, sanded, sealed with WBPU, painted and top-coated with WBPU.
Phase 3 F-16 Same method as F-18
Fly Fly 90mm F4 No fill. Just painted and top-coated with WBPU. Not as good looking up close, but still OK.
Intake with the Forward Fuselage removed
Left intake with Forward fuselage on.
Distance from intake to Fan is about 14.5 inches.
Big Nose gear door open
Wheels almost all the way up.
Hobby Top Gun next to Fly Fly Products F-100, F-4, Hawk and MB-339 for size comparison
Well it looks like it's bigger than all but the F-100
L-39 next to F-100
First things first. I joined the wing and glued the vertical to the plane. Notice the front Spar/Former is now different.
all connections ready and tested.
The AAAHHHHH moment, First time I put it together
then I start to Fill, Sand again
Heck I even Filled where the Wing Bolts will be mounted, I will redrill the holes from the other side of the wing, where they are still exposed.
It was a weekend of Sanding, I also worked on a Top Gun F-15 and then another plane. Can you identify that canopy?
You can see a couple of small spots where I filled in again
It's hard to see, but there are four parts where I had to fill yet again
One side of the wing is nice and smooth, the other I have yet to sand down. I added extra filling just so that it would show up for the picture, YEEAAYY, now more to sand :(
.14 sec, 21.0oz.in at 4.8v, 8.0g
You can see the Fuselage is shiny from the intakes back but not the tail. The shiny parts are final sanded and ready for paint.
Same as before just different angle
In the intake, you can see the parts that have been coated with WBPU and inside the intake is the bear foam.
from a side shot you see it nice and shiny, ready for paint.
front a head on shot, you can see the honeycomb like pattern of the foam. It is more visible because the WBPU filled in all the small crevices leaving a smooth surface
same shot as before, different angle.
New package waiting
EMS finally came through
Double boxed, Everything survived perfectly
New Fan 6 Blade Fan and motor, This shot was after I ran the motor and I bolted it out of round. This demands a J-39 sacrify since I need another Fan Housing now.
ALL check out the new struts and Way better wheels. If you notice the Mains are now Rubber like say a Dubro Wheel while the nose still foam. Thicker struts rivited old style was screws.
bottom of Fan where it rubbed
I think this one will show better where the housing started to get soft / melt
Compare Retract with stock gear. The stock gear block, has an extra screw to hold it in place.
I drilled them out with a .21 size drill bit.
servo and light wires now covered / filled at least half way
new retract plate. I just added this to have more of a glue joint to the foam
new strut and tire
same but in the up position
No this was just to show a small piece of the WBPU that I removed. It adds a small skin like to covering to the foam. Not dent resistant, but it does make the foam a little stronger.
Bug in the fuselage
I just sanded over it and covered it UP
Wing construction is done minus the hinges for Flaps. Nice and smooth
I started feeling a little blue already
First coat was left light to make sure I didn't get any runs
Second round with Rattle Can, I still have light panel lines showing, but those look MUCH better now, most disappear in the paint.
letting it dry
Flap installed and hinged at the bottom at a 45 angle to the flap and wing.
Model Master Paint
Model Masters Bright Yellow
just covered it up with Blue masking tape.
First coat of Yellow
Looks nice, but I pulled the tape too hard in some spots and now I need to re-apint some touch up's :(
Motor contact patches and mount indents.
N# Seven on the Left hand side tape out
Tape out the Yellow where I pulled the tape too hard
Now I just have to worrry about the blue
Fan trial fitted in
Nose gear all ready to go, Notice the space / gap between frame and steering arm
parts needed to complete Mains minus Strut and wheel
Space between steering arm and frame
Items needed for Nose gear, notice the mains are ready to go
Waiting for paint to dry on rims and struts.
The paint on the landing gear still felt a little sticky so I put it out on the sun.
Bottom of the wing is not painted.
canopy frame now painted along with the wing
Now she looks like a plane
Trying to et a good shot while the Wing Tip light is on
Decals I am ordering
Mu retract was not going in all the way, notice the small gap between the strut and the retract frame.
One retract strarted to unscrew at the base.
All cleaned up and retracted on it's own power
"All aboard" PK wrong theme, but at least I got pilots, one of them was even the right color
You have to forgive me if I have no desire to go out and fly right now. Yesterday was HOTTER.
Rear decal with the protective plastic not removed yet. The Shiny piece at the front is a Paper Towel piece to help remove the plastic
Same with the Blue Angels, you can see where I stuck a piece of paper towel in the corners to make it easier to lift it back out.
Over All view
Plastic removed from Nose
New pilots are too tall. the seat will have to be removed and the pilot trimmed
Here they are before the chopping begins
Ahhh, I fell like such a bad boy for cutting them up LOL.
another view. Seat removed and pilots cut down a bit
