Dropped by Hans yesterday and took in the new T33 build, otherwise known as the Shooting Star…and now for some history. One of the very first of the USAF and Navy jet planes. To quote the world wide interweb…. The Lockheed T-33 Shooting Star (or T-Bird) is an American jet trainer aircraft. It was produced
I have decided to build a T33 for my PSS (powered scale soaring) entry for this years event. Here are some of the dimensions and my progress so far. Size: 1/3.8 Length: 3m Span: 3.2m (with wing tanks). Colour scheme: Miss America / Thunderbirds. Wing section: SD6060 airfoil Fuselage is styrofoam, cut in sections. The
July 2012 PSS project Graham Dorsell/Traplet plan and wood pack Wingspan 68″ Length 65″ All up Weight 5Kg(As a slope soarer the wieght will be less) This was the beginning of the scratch build.My wife alloud me into the spare bedroom as my hobby
So the PSS festival was a blast and for the 6 individuals who then went back up the hill
it turned into a great day. After hiding under trees for an hour the rain finally let up and
we were able to send out the big birds. Steve first with the Bearcat, in at 6 kilo’s
then myself with the Connie in at 5 kilos and then Mally’s large and very impressive Dakota in at 9 kilo’s
Boy what fun, nerves all a jangle, adrenaline through the roof
and three very happy slopers. Thanks to Jeff for getting all three launches more or less correct
Let the pics talk for themselves…
Connie completed, for this year at least and for the maiden flight.
350hrs+ in the making and about 16 months of Saturdays and Sundays
as I tend not to work during the week, except during summer when the daylight hours allow it.
To keep the surprise element in place, should you wish to see Connie live,
and hopefully airborne… please join us at the Black Eagle PSS Festival
on the 23rd June at a slope near us –
hopefully Chapmans Peak, but a venue will be posted 24 hours prior
See you there!
Connie under wraps till event day
no, there will be no maiden till then either
so could be a fun day all round:-)
Finally, I get to the decal stage of the project,
and to be honest the part I enjoy the most
Would love to paint pretty planes all day long…
if somebody else would just build the bleeding things.
First set of decals I did at work were off our stock standard high end printer.
Ran home, decalled an entire side of the fuselage and then went to put it in the shed…
and that when a rain drop hit it and the decals smeared in an “oh so not pleasant” sort of a way.
So back inside to take them all off and go to plan B…Find a professional printer
that has solvent based digital printer and get them done there.
In the end a nice thin film, hard as nails print and nice and easy to apply.
So watch that the prints you get done are in fact solvent based on the clear film
or you could have a bit ob a bleed on the go.
Decals being applied. Both sides of the plane are different in window placement
door placement etc, things that could quite easily trip you up
in the details stakes, so a lot of staring at pics took place
making sure that left was left and right…
The wing completed and decals applied to and bottom
with the odd air grid etc in place
The tail surface gets a lick of decals
again paying attention to the left right issue
and checking all the streepies line up
and onto the tip tanks.Carved out of foam, and then glassed,
I was very particular about their shape. Most of the models
I have seen make them round, and the plans called for that,
but the more I studies the real plane the more the tip tanks
took on a differing slightly gold fish sort of look and feel.
So after a bout a week of working the glass out the final
product looks pretty close to the real thing.
Getting a neat fit to the wing with epoxy/ micro balloons mix
Decals set in place and so to the screw that will keep them on long enough to fly
and the inside of the other one completed
Now time to sort out the CG and put the completed beast together
Ok, so basically Connie structure is complete, all surfaces are in and working
All electrics are inboard and all looms in place, battery pack etc all there.
So a few final little bits and pieces to do….
The spinners were driving me nuts as there are a specific shape
so I eventually found some that were of the correct proportion.
Slightly longer than normal, I had to backfill all the prop openings and spray to aluminum finish…x4.
Then I had to create the sleeve that the spinners come out of, that covers the motors,
luckily found a molded bit of plastic from servo trays and backfilled with balsa.
Then borrow Andy’s drill press, fit with a toothed circle cutter,
and try like hell to center the hole in said plastic bits x 4…
A few whiskeys later and this was a cinch.
Boy did this take time, but in the end came out all right me thinks.
Thank you Andy – drill press now on the shopping list
First test spinner in place – 3 more to do
Beginning to look more like the real thing
Black leading edge boots in place – de-icers actually on the real thing
Air intakes with some shape and colour
and finally 4 spinners in place….
OK, so where were we…
Fuselage covered, tail covered and onto the wing covering
This understandably took some time with all the complex curves
around the nacelle mounts etc, so I did those first
and then came back to covering the rest of the wing surfaces.
This meant I could overlap the film onto the covered nacelles
and so get the best possible seamless joints.
Unfortunately the grey of the covering was too light so
I would have to spray over the orocover. A 1000 grit paper
given a light dust over the cover resulted in a good bind for
the grey base coat, followed by the colour coat.
Ailerons getting covered, with the tools of the trade, orocover,
special iron ( available at a hobby shop near you), ruler, scissors and a sharp knife
Servo hatches get the same colour
as do the nacelle mounts
and then to cover the basic wing area
and after some work, one half covered.
and onto side two, note the flaps are cyno hinged as well as using orocover
to cover the base hinge line
Getting the cover over the tips and as before, heated and re-heated till all wrinkles vanish
Robart hinges about to be given a smattering of Vaseline to protect the joints
it seems as if they even smell epoxy they tend to get sticky, and noisy
so grease the joints well, add epoxy and you will escape the sticky joint issue..
Hinges at 60 degrees to ensure that they are all straight as a dime
and lined up to stop any binding
Wing gets a grey primer and then the colour coat
Playing chase the string as I set up the loom. First went in with string attached to plastic tube,
then attached the servo leads to the string, pulled the string through
and had the servo leads out the other side
and metal gear sevos firmly in place, for this I used the trusted gws 8mbb servos
and adding the plugs back on the other side
Control horns in place and push rods set through the wing
all the plumbing for this was done way ahead of the covering
Basic wing completed and functional with ailerons in place
and a full crow system operational
Right. Now to add some sticky bits with colour – decals.
New tail made.
Hinges and wipers are installed.
Servos in the wing are mounted from the hinge gap, so no hatches e.t.c.
Canopy get’s a scale interior.
Spraying of the model soon.
