Hi you all Wattflyers!

I have built 2 months 1/4 scale spitfire plugs. fuse and tailplane plugs is almost woodready. so this will be full composite plane (wings too). i will hammer litho plate all over the plugs with all rivets and screws.
weight goal in this plane is 12-13kg so i will try some 'smart'laminating and put cloth only to places where its needed. 2-3kg lighter plane than gas version of 1/4 scale spitfire. so its extrem build. thin laminating and partially sandwiched.
motor will be AXI 5360 with Jeti 90+ or spin 99. propeller is 3-blade one from soloprops. landing gear option is still open. i'll maybe build those myself because there is not shorter mk1a type landingears on market.
same reason i have done with lathe also the spinner plug. backplate under process. so it will be done from carbon.
any comments is wellcome!!

Hi!
yes there have been some progress here.
fuse plug is ready for litho covering. tailplane is allready litho covered and ready for molding.
wing panels uppersides is already sheeted with balsa. so soon bottom side and glassing. and then those are also ready for litho plate.
i will soon take pics from those also.
here some pics from progress...

cheers

Very impressive lithoplate work. This will be a big plane at 12 to 13 kg (26.4 to 26.8 lbs). Do I understand that this is the plug that you are creating for molds?

19thsqn
01-23-2007, 02:44 AM
Yes, i will do molds from fuse, wings and tailplane.
laminates for plane will be 30% thinner than normally in gassers. lower vibrations allow lighter laminates.
i know its hard goal. going to use same kind of construction than some of composite hollow wing gliders. lots of carbon hybrid fabrics. stiff and strong.

19thsqn
01-23-2007, 07:10 AM
i have also worked with smaller gasser spitty.
and i just like the lithoplate material so much.
and i have noticed its a lot easier to do more accurate rivets and details in 1/4 scale. so i wait a lot from this project...

19thsqn
01-25-2007, 02:33 PM
wing panels are now sheeted. im happy how i got straight trailing edge to wing. it was a time when this was real issue to me.
when sheeting bottom surface, i placed 10mm x 10mm hard balsa to both sides and used many clamps to keep sheetings and balsa spars on place.
when i have glassed wing panels, i will cut ailerons away from wings. then i have ailerons with proper wash-out.
and of course there was jigs on both ends of panels to get that wash-out.

I received axi 5360 motor today!!
what can i say, its truly a giant.
my hand is not so thiny, the motor really is that big.
look the huge support bearing.
i will soon receive jeti spin99 controller.
there is few very good advantages in it.
like u can make throttle control a lot slowlier. from 0-to full speed 5-7 seconds. very cool thing when having giant 30inch solo prop.
and adjusting and reading inflight measurements(amps, volts, rpms)
from jeti box..

like a christmas....

19thsqn-- Coming along nicely. You are certainly a master modeler.

01-30-2007, 01:40 AM
Thanks from very kind words bros!
peak power will be with 10lipo around 3kw. watt/weight ratio will be about 90w/lbs or 200w/kg. should be enough for good performance.
specially coz it turns very effective huge prop.
here is pics from 1 huge plane with same motor.
aeronca champ
35lbs 168inch , 16kg 427cm span

so i believe its good choice for my very slim and a lot smaller spitty..:rolleyes:
(8lbs/4kg lighter,58inch/147cm narrower, and 1/2 thinner plane)

will run it with 10lipo first, but if i feel needing more rpm i will use 12lipo
, but i think it wont be needed.

cheers

i got today outer wing panels done...
and im soooooo happy. these are my 3rd spitfire wings builded, and finally im happy with those. identical wings with straight and sharp trailing edge. and correct shape leading edge. i just opened a beer...
and i had to test a how it fits with fuse... at least one wing... ;)
some filler is drying in pics...

now my surfboard is wood ready.
surfer (me) trying to reach the tip...
next i need to build mold from tail plane, after that installing the tailplane plug to fuse plug, and finally fin. then main plugs r ready for litho plate...
if working real hard this will fly at summer... :rolleyes:

Thanks from kind words!
i have ordered vacuum pump and all the suplyes for vacuuming. should be here at any day. i will build this spitty partially with foam sandwich construction. i will do some test laminates with tail plane... practise is always needed... ;)

19thsqn
02-22-2007, 05:49 PM
Ok!
i just wanted to put pcs together and look what kind of monster is coming...if some one thinks why fin is not glued on its place, i will make first mold from tailplane, 2nd laminate centerpart of tailplane and glued it on its place, then fin on it and lithoplate. it will fit perfectly then.
and in pics u see mick reeves scale tapes for fabric reinforcing. elevator is not ready yet, some litho and trim controls still missing in pics...
pics r better than my english.....
on floor my relaxing plane... american ace old timer..

03-02-2007, 03:10 AM
Jiihhaa..
just got my Jeti 99spin controller and programming box. now waiting batteries.
that jetibox gives all the information from flight too. and one most important is slowing the throttle from 0 to full, upp to 7 seconds.
very important thing when turning 30inch propeller. easing the torque. all the gear on 4inch balsa, just giving idea from dimensions.

03-04-2007, 07:30 PM
Hi,
I joined this forum some time ago but had not yet posted on here as i am still just tinkering with electric flight. But boy! this model has caught my attention big time! It is a truly stunning model and i will be watching with great interest as you progress. Well done with it so far.
All the best,

Hi Walts! wellcome to forum! im so jealous, you guys on the otherside channel have soooo many beautiful spittyes there. maybe need to visit there in duxford or bigginhill in airshows. i was ill almost two weeks, and now i start working again with spittye. meanwhile i almost finished my relaxing oldtimer... ;)

cheers

walts
03-05-2007, 09:22 PM
Hi 19thsqn,
I know what you mean about the spits, we kind of just take it for granted. I was at Duxford a few years back for a special celebration show, I think it may have been a battle of britain celebration, and there was 22 spitfires doing seperate slots. Then the commentator Made an announcement over the P.A. He said "This has never been allowed before but if you look behind yourselfs you will see ALL! 22 Spits approaching in formation for a low fly by over the crowd...............Absolutely amazing sight & sound, Glad i went to that show:)
Take care,
Walts

03-12-2007, 07:05 PM
well back on spitty..
i started hammering panels to wingplug. i annealed first the litho plate, then hammered the rivets with sharpened tube. then glued with contact glue.
the leading edge of spitty wing is one of hardest to shape. coz of the double curvature and v shape of wing.
here pics...

19thsqn
03-21-2007, 05:06 AM
here how i work with litho.
-anneling litho with low cost torch. colorside of lithoplate works as a indicator, when its lightly brown its ready.
-then cutting panel to shape
-drawning the rivetlines with pen
-shaping the blister cores from balsa. then forcing tha alloy over the core with hard balsa block. glue the core to panel.
-hammering the rivets and small screws to panel
-contact glue to panel and plug. waiting 15minutes, then rubbing the panel to plug with balsa block.
-after all scotch brightening patch is good for smoothening the surface and killing the sharp edges lightly. better releasing for mold.
in pic i read factory blueprints and drawning the rivetlines...
cheers

Hi 19Sq.
Nice project and a lot of work;) . Is it a one model project?

I would like to have some spare time for a D190 that has been awaiting in the building board for a long time.

Cheers.

03-23-2007, 09:43 AM
Truely amazing work :cool: I recently made the tail fairing front cover for my Hurricane from litho and it took a few attempts to get this little bit half decent! I don't think i would have the paitence to do what you have done, fantastic, keep at it mate.

Walts

19thsqn
03-24-2007, 07:40 AM
Hi!
realism is the goal!! so i think real alloy is the key.
in my smaller spitty it took 8 months to hammer those lithoplates. since then i have learned a lot, believing 3-4 months is truly realistic. trying to build all molds at summer.
so i know what kind of zen-buddhism is needed.. ;)

19thsqn
03-26-2007, 05:51 AM
Hi again.
i will do molds from all parts. and if it flyes well, maybe sell few planes to cover costs, like a limited serie. this is still a hobby for me...

I will mold ailerons with wings. then i have proper wash out in ailerons too. left on is done and right one half away (upper skins)
mick reeves scale tape used on ribs... and reading blueprints all the time...

19thsqn
03-29-2007, 12:04 PM
..i was helping my friend with composites and on side laminated spinner mold.
it was extrem tight on spinner plug. but finally i got it off. mold is 8mm thick. so i think it lasts forever...
when im bored about hammering.. i will make carbon spinner. after that i working with backplate plug...

19thsqn
04-10-2007, 01:39 AM
..More panels.. on wing tips is less rivets. so panels are now kinda easy to do at this point.
2-3 more days and upper surface is ready...

walts
04-10-2007, 09:20 PM
This is looking really good, one of the best scale models I've seen for detail. Keep at it, I'm looking forward to seeing it finished, Top stuff!!

Walts

19thsqn
04-13-2007, 02:01 AM
Thanks Walts! i cant wait either!! ;)
Time for a beer!!
upper surface is hammered. later i will smoothen the surface littlebit with scotch brightening pad. makes panels edges softer (you cant see with eye it, but can feel it by hand) makes mold release much easier.
i started cutting bottom panels....

drksyd
04-15-2007, 08:49 AM
Outstanding job! I doubt I could afford one but I'm sure you'd be able to sell a good amout of your Spits. Keep up the great work.

19thsqn
04-15-2007, 03:54 PM
Thanks!
i have ordered centering pins, inserts, bolts and special gelcoat resin for molds. so if the plane flyes nicely, those molds will last many pull outs as possible. and easy to use vacuum bags because its easy to take pins away from mold. hoping to start making tailplane molds in any day.. just because its nice change for hammering... ;)

will show that later....

19thsqn
04-16-2007, 05:36 PM
hello!
i started hammering bottom side of wing panels.
i think one of most diffucult part in spitfire wing is leading edge panels. and how to get those fit together.. this time im happy with result... it wasnt easy...
sorry about dirt... smoothening and cleaning undone... scotch brightening needed... ;)

Thanks for kind words!! those keeps me going! ;)
it was a time for break... about hammering.
i laminated spinner from carbonhybrid cloth. its very stiff. stiffer than any alloy spinner.
now backplate under process...

19thsqn
04-18-2007, 01:43 PM
just put spinner on scale... and weight is 106grams. slotted the spinner while i was hammering panels.....
soloblades in picture are too small, i need to order 30inch blades soon..

04-23-2007, 06:16 PM
working now on bottom side of wing... very easy panels only.. all the difficult panels is done. and making some drawnings before cutting panels. spinner backplate plug is under waxing...
when backplate is laminated i will smoothen it in lathe and cut huge lightening holes in it. and balancing too ofcourse.

19thsqn
04-25-2007, 02:40 PM
center part of wing hammered on bottom side. now gulwing is clearly seen here. id light.
just tell me if there is too many hammering pictures... ;)

there is much less details on early mk1 spitfire wing, because it was designed as defender. later mark planes was attackers with external tank, bombs, rockets etc.

i got landing gear from Sierra Giant!! http://www.sierragiant.com/index.htm (http://www.sierragiant.com/index.htm)
these truly are pcs of art!!! perfect scale and feels very strong! i believe those will last life time. and one thing i like too, these are very light!!
now just need to try my best with spitfire and make justice for these retracts!
thank you Darrel!!

I just did some painting last weekend (house, not planes:D) for an 84 year old club member who is working on an 80" Spitfire. He has the fuse and wing fully built up. Looking at the fuse, being all built up sheeted construction, was just incredible. No way of telling that it wasn't glass. He plans to add all the rivets, like this build here.

Hi Bill! rivets indeed make the difference. if you have pictures, please send it here! ;) i have made flap, aileron plugs ready today. now there is only flat plates left on wing.. i will take pictures tomorrow. not many days and wing plug is 100% done.
.... then start fuselage.

i have made some sirious shopping again. in plane will be Benedini 50v/50w soundsystem with 130mm/5inch visaton speaker.
fuse will be partially sealed as a sound box. giving best possible sound. sound system weight with speaker is 568g/1,25lbs.
power will be taken from driving battery so there is no extra battery. sound system will give out 102db pressure.
thanks for information Tor Arne!!
and Carl Peter from Soloprops will build havilland type blades for spitty. i cant wait those!!! http://image.rcuniverse.com/forum/image/s2.gif
so all the hard wear is ordered for this project.

rivet detail from fuse. many people is miss leaded to think spitfire have all rivets rised behind cockpit. thats false.

as u see its not big! and speaker will be in cowl were normally is firewall. so it doesnt add much weight! just working like living ballast. fuel tank area will work like soundbox for speaker.

Hi Rumen!
minimum is 4 pcs! but i believe in the end it will 7 or 8. depends what i decide... not ready with my mind yet! but i will tell that when i know.
how its going with bigger me-109? or is there too hot?
its been too hot to work here few days. but molds will be hard for sure! heat is good for those.

FUSE MOLD LAMINATED!!!!! IM SOOO TIRED... last 2 weeks been waxing and laminated almost every day... yes i still have my full day job. long days. tomorrow i will clean the edges and after that few days waiting. let the mold cure in peace. its not easy to wait the results..... http://image.rcuniverse.com/forum/image/s2.gif
no im not going to rest... i will cut the wing ribs and spars... and apply frekote to wing molds...
at this point 80kg epoxy is used and 20liters chopped fibers, hundreds meters of glass, 2boxes of nitrile gloves, 3 cans of wax, 2 liters of frekote, list goes on........
just let you know what it takes to build mold for 1/4 scale bird.....
soon pics!!

Congratulations on some truly inspiring work!!

I'm about to start my 3rd all electric 101" B-25 Mitchell and would love to try your building method. My previous ones have been around 35 -36lb AUW. Do you have any idea or guesses as to what weight savings might be possible using your construction over traditional balsa/ply construction?

Thanks
Richard

Hi Richard!
1st let you know fuse mold is opened and its good! ;)
my home internet connection wasnt working yesterday, when its working pics! #1 fuse will be laminated at monday!!
Richard, if you want build lighter than traditional build, its really need to be sandwiched. if building full glass plane with out sandwich materials, it will be littlebit heavier but can take much more hits coz it will flex littlebit more and bounce. example comp-arf 2,6meter planes using 80g/m2 glass on both side of 2mm herex. and those planes really are light!

Hi Fokke!
i think 2x160g behind balance point is perfect and frontside of BP it should be good with 3x160g. then it will be light. small stripe styrofoam or airex between clothsin back fuse adds a lot stiffness. or just make 2-3 light formers.
hope this helps.

Jukka,

I have been reading through your posts with awe! I to am wanting to cover a model with lithoplate, but don't really have any idea where to start. Are you able to please explain the lithoplate forming and application processes in a little more detail, perhaps with some photos too? What tools do you use? Do you actually "hammer" the metal, or do you rub it and stretch it into shape with a wooden tool? Any tips and/or info would be much appreciated.

Regards,

James.

Hi James!
in early page is some pictures from tools too.
at first i cut the panel to shape. then i heated the lithoplate from clear side (with butane/propane torch) so the colorside of used lithoplate turns lightly brown. colour works as a indicator. heating takes only few seconds per area. then let it cool down, it stays soft after that. then hammer the rivet lines with correct size sharpened tube. rub the ready made panel with balsa wood block on plug. then apply contact glue for both sides, wait for 10-20mins. then put the panel on plug to correct place, stays permanently right away. if it goes wrong use torch and heat the panel and pull it off. rised rivets was hammered first from backside of panel with dremel small ballend tool then flip the panel and hammer down with sharpened tube those rised rivets.
hope this helps!

cheers

Jukka

09-25-2007, 02:36 AM
Jukka,

Yes, I did see that, thanks. However, how do you do the complex compound curves, such as the leading edge and cowl? Do you have to keep re-annealing the panel because of it work hardening? Do you rub it to shape with the balsa block onto the plug before you apply the glue? If so, how do you hold it in place while shaping it?

Thanks,

James.

19thsqn
09-25-2007, 02:55 AM
in long panels example leading edge i start rubbing from centre of panel. and keeping the panel on place with painters tape. and adding more tape all the time with progress. the glue comes after the rivets are done and panel shaped to curves. in cowl area i hammered those panels almost to shape (on solid balsa block with round hammer) and then rubbed it on plug. then rivets, and rubbed again. then at last glue.

Nice project. One of my club members, a WWII vet who served in Britain, is building a large Spitfire. I think Ziroli. Your project just reminded me that I need to stop over there and see the progress. When I last saw it, he had the fuse fully sheeted and was sanding coats of primer.

These large Spit fuses are just beautiful to look at. The pics don't do them justice. You really gotta see them in person to get the real effect.

the method i used was:
gelcoat by brush. let it gelled. it doesnt stick to your finger but you can push your finger print on it, then 50g glass. let it gelled again so its lightly sticky. rub the dry coremat xi on it! then saturated it with epoxy by rubber gloves. rubbing for while to shape. with paper take away excessive resin. apply inner glass 50g. then carbon spars and reinforcings. when gelled well cutting edges.

oh, just- WOW. this is incredible! You should either be locked in a mental institution or given a Nobel Prize. Maybe both?
looks brilliant- I love the lines of the spitfire. Maybe it had to do with growing up living under one: my father built a 1/5 scale spit from a kit by Pica years and years ago. He's never flown it, which seems a tragedy. The work is beautiful... if i'm not mistaken, he even cast his own functioning manifolds from alumnium so that the exhaust (glow engine) would 'look right'.

And to think i used to believe he was crazy for putting that level of work into something.
keep up the work, this is astonishing! :D

Hi Jukka.
Have to agree with all the others: an absolutely awsome build!!! Want one of these too!!

What power/battery set-up are you going to use with that motor? Got one myself to drive a 4-bladed 24" scale airscrew for my TF GS Mustang. Using a JETI SPIN 200 and 4x6S, 5000mAh LiPo's two paralell and two in series for a total of 10.000 mAh and 44,4V.

Don't know yet what kind of flight time this will give but bench tests have been very positive so far. Sure is that it will be a very powerful machine...

What power/battery set-up are you going to use with that motor? Got one myself to drive a 4-bladed 24" scale airscrew for my TF GS Mustang. Using a JETI SPIN 200 and 4x6S, 5000mAh LiPo's two paralell and two in series for a total of 10.000 mAh and 44,4V.

Don't know yet what kind of flight time this will give but bench tests have been very positive so far. Sure is that it will be a very powerful machine...

Hi Benny! your mustang will be like bullet!! lots of power!!!
electric kilowatts is claimed to be 30 % stronger than gasoline versions.
so depending what motor u will be using, u will have endless vertical power. i will try first with jeti 99 spin same kind of battery sett than u have! jeti spin 99 gives 110amp bursts and designed 90amps continous.
4000watt continous power, 4900watt bursts... if this is not enought i change the controller to spin 200. but it should be enough! for scale like flying.. more amps shortens the flight time... will see how it goes!
let us know hou your mustang works!!

cheers

Jukka

Didn't the builder/designer develop an allergy to epoxy,and sell the moulds to fighteraces.com?
Ali Machinchy I believe,has one up and running made by Phil Clark in the UK, with a big Hacker and sound system-assuming the model is the same one?

Is that correct?

Edit: Just read back a page, yes it is the same one.
I've seen pics in a UK mag,and it is darned beautiful!

Jukka's last visit was 11/7/08. I doubt we're going to get any more updates on this thread. A shame too, I was looking forward to seeing the final product!

Although I think I may have found a video of one. I belive this is Ali Machinchy flying one with a Wren turboprop:
