RE: Electric 1/4 Spitfire MK1A full composite
Wow, Tetsa!!! you truly are lightning fast builder!! (i did know that) 
indeed #1 will be later in air than #2. i will work hard for your parts next two weeks. i promised to do some installions to wing for Tetsa. almost plug and play.
so we work together making maiden, if possible, before winter...
i almost finished elevator plugs today, only trim covers missing. tomorrow rudder plug.
.. release agents and mold making at end of week.
so this thread will be updated daily, i think....
cheers
Jukka
p.s. David! keep working hard!! hope the tf spitty flyes at next summer again...

RE: Electric 1/4 Spitfire MK1A full composite
Thanks, Jukka, the little Spit is on my bench with a new front end waiting for glue, as well as a new GRP cowl. It will certainly be in the air next summer, but I am hoping to see the 1/4 scale models up there first.

Wow Tetsa, you're introducing me into a whole new world cooling and any related problems.
I'm seriously looking forward to see (and sincerly hoping for the best) how the cooling (engine and can) tuns out.

RE: Electric 1/4 Spitfire MK1A full composite
Good morning.
coz weight of the plane will be around 20kg 40-44lbs, i will update the motor...
it will be hacker A200 + master spin 300 opto. 15000w =20hp.
my soloprop adapter fits perfectly on it. (dehavilland blades arrived to finland today,pics later)
and it turns easily 3 blade scale propeller...
cheers

Astonishing work indeed, my compliments!
How many Lipos or LiFE do you intend to use? Have you predicted the amperes involved?
Best regards
Pierluigi

RE: Electric 1/4 Spitfire MK1A full composite
Hi i have 10 and 12 cell lipos. mah 9000 to 9800. i have for axi 5360 jeti 99spin controller. its just about enough for scale like flying. but i think some extra would be good.
75amps/20second for axi.... some short periods can use extra amps. spins 3200rpm with 30x20 propeller in air propably more. but i believe ineed more power.. with axi only 150w/kg

Hi!
i got my scale blades from Carl! He did absolutely beautiful job!!! i love these blades!!!! THANK YOU, CARL!!! soloprops rule!
and i was testing my tires. rims are from glennis aircraft. i putted airfilled tires on it. littlebit soft but ok.
too bad spinner backplateplug wasnt at home... but for sure all is coming together slowly...
cheers
Jukka
p.s. sorry about the dust... im cleaning now... [&o]

RE: Electric 1/4 Spitfire MK1A full composite
Those blades look seriously good! I'm still waiting for my 26" blades (standard round tip) from Carl. Hopefully I'll get them next week.
Today I'm building the radioplate / canister support structure, and possibly the pushrod installation for the rudder and elevators. I'm using 8 mm carbon rod with 3mm ball links. For the radio plate I laminated some heavy glassfiber cloth on both sides of a balsa sheet. This should make a really tuff structure.
The fuse is so long that I'm going to have to make the pushrods in two parts, with a two sided horn in the middle. I really can't remember what that bit in the middle is called, but I'm sure you people know what I'm talking about... I'll post some pictures later.

RE: Electric 1/4 Spitfire MK1A full composite
Tetsa,
I think you mean a bell crank. The real spitfire had two in the tail in a vertical orientation from an axle that was fixed to a former just infront of the tail plane. The bellcrank actuated push rods that extened aft to the control surfaces, but was controlled by pull-pull cables running forward to the steering yoke. I hope to duplicate this structure in the 1/7 spitfire I'm working on. Any reason you wouldn't use a pull-pull system to save weight?
Guys are always talking about this but I wondered if with carbon pushrods it isn't a negligible savings. I certainly like the simplicity of a push rod if flex can be controlled and straight-line, uniform actuation achieved.

You're a sick man grumpy!
I can see how you're getting your kicks in bed you dirty little devil!
And that prop... Wicked!
This is turning into RC scale porno'
People all over the world are doing themselve over this thread.
When is it going to be banned?

RE: Electric 1/4 Spitfire MK1A full composite
Bla Bla, I think you have some small issues dude...
Anyway. Today I was supposed to do a little bit of this and that to the Spit, but I was so lazy that only managed to glue some rails in the fuse. The rails are for bolting other stuff to it. Like the tank-holding former I managed to cut from balsa and ply. Please note that the rails are merely tacked in place at this point.
That's about it for today.
Rick: Actually I don't think that the CF rods are that light. How ever, they are very stiff. And since thet are so stiff, I don't need to support them in any way! Your pull-pull idea is very good, but I don't see how the mechanics could be installed in the back of the fuse without cutting rather large holes.

RE: Electric 1/4 Spitfire MK1A full composite
[X(] you're on to me.... its not a crime... 
good progress Tetsa!! indeed its not lot of room for pull pull system. but there is scale places for pushrods.
i started working with last molds!!!! partingboard made and release agents applied!!
tomorrow laminating those! when both sides is laminated i will separate those 3 molds with band saw.
so... i''ll be back!
cheers

RE: Electric 1/4 Spitfire MK1A full composite
Well... i did find the urge to carry on. So now my radioplate is ready. The canister seems to be quite close to the servos in the picture, but there's actually plenty of room, since the can is well above (or below, really) the plate. The next thing is to make a clamp to hold the canister to the radioplate. I'll cut/bend the clamp from 0.8mm aluminium. Also I have some really nice M3 isolation bolts to reduce vibration from the can to the plate. So that's tomorrows job along with the pushrods.
Oh! About the servos... My order of Hitec servos from Al's shop is taking longer than expected, so I went through my drawers and found pretty good substitutes. The two after most servos are Futaba 9151 digi's, these are for elevator halfs. The single servo with the large horn is for rudder, a Hitec 5625MG. The two "bundled" servos are for throttle (Futaba 9255) and choke (Futaba 3001). Incidently, the 3001 is the only analog servo on the plane.
The 9255 might seem a bit over the top for the throttle, but I've found that you really benefit from an accurate servo for that application.

RE: Electric 1/4 Spitfire MK1A full composite
Well, It turned out that I really should read my mails from start to finish... So some time ago, shortly after my servo order, I received a mail from Al's Hobbies that said the servos are out of stock and it's going to take a few days before they can be shipped to me. This is where i stopped reading... The next bit was about me contacting Al's hobbies staff if I still want to continue with the order... So me being without these servos is totally my own fault. Well... Lesson learned: Read those mails from start to finish.
I do apologize for making this a public matter in my previous post, and I must thank Ali again for his effort and for being a true gentleman about all this. Thank you!
Tero
PS: I started working on those bellcranks and engine baffling. I'll post pictures when I have something to show.

Hi!
Elevator and rudders molds opened and those are perfect! plugs took off from mold very easily. and i have cutted wood parts for Teros #2 wing. today i will make horns for it. and cleaning edges from control molds and applying release agents on those.
so all the main molds is done.... [sm=52_52.gif] some silicone molds need to be done for scale details. but these are very relaxing to build. take only minutes to build molds for those.
cheers

Hi Skypilot1!
all you need is patience... and reading users manuals. no special skills or machines..
it did happened.... im out of epoxy... i have ordered big can of epoxy, its already in harbour. so next week more progress.
while waiting, i'll work with details. well those details need to be done, but winter is coming, and 1 week delay is not a good thing...
brrrr it starts to be cold here....
more spirits keeps my blood running...
cheers

RE: Electric 1/4 Spitfire MK1A full composite
Patience, talent, skill and if married, a saint for a spouse.
I can hardly wait to hear how it flys. If it is set up like a Reeves it should fly great from what I have read. A video of this bad daddy flying should get bla bla to cream buckets. Me too!If you can get a top scale pilot to do the maiden I'm sure you would get enough orders to require buying a few hundred gallons of epoxy.
I think you wrote it before but how many gallons of epoxy goes into one complete spitfire? How much cloth? The materials for the layup alone must really add up not to mention the quantity in the moulds plus all the time you have in this project. I really commend you for your efforts. You could probably charge $4000.00 each for these but it would be out of reach for all but the elite. I could see these in airports and museums with a 1/4 scale ME-109 in it's sites.
The only negative might be that in some areas of the annealed lithoplate texture detail on the fuselage looks a little too much (post 190 last photo) but I have never seen a full scale Spitfire up close so I could be totally wrong and I oplogize for saying it. Do you think it will be toned down after it's painted? I went back and looked at the photos again and it looks so good but at the same time it looks maybe a little more textured than scale. Do the think it is just thephotos?

RE: Electric 1/4 Spitfire MK1A full composite
No problem!
the war time spitfires was very wrinkled. nowadays those spitfires which are flying are too smooth and too much taken care compare to warplanes. and if you are talking about rivets, i believe those will look perfect after paint, dirt and weathering.
if some one wants smoother rivets, primer will do the work. i wont use any primers. i want to simulate very chipped paint alloy showing in edges, rivets and some other details. and rivets are scale size...
i have high quality pictures form mk1a spitfire from imperial museum. but im not going to publish these coz i dont have copyright to these pictures... sorry about that.
i have 3000 pictures from spitfire....
cheers

RE: Electric 1/4 Spitfire MK1A full composite
and about material cost and pricing...
i have used only high quality epoxy in molds and parts. at his poin 100kg (35€/kg) limit in epoxy is broken. 400meters different kind of cloth spend. 100pair of aligning pins. 100pair of inserts. 300rubber gloves. 5liters frekote release agent. almost 4 cans of wax.
20-30liters of chopped fibers. 40-50brush. 15liters thixotrophic. 30liters acetone. plus many other.... and about 1000hours.
material cost for one plane for one plane is 700-800€+ taxes. and this not include all above... for one plane i need to work 2 weeks all my free time. so for one plane 2500€ is very low price.... take your calculator... i promise i wont sell any planes under that. i rather
enjoy my spitty with Tero. im not mad, not going to work free.... [

20-30liters of chopped fibers. 40-50brush. 15liters thixotrophic. 30liters acetone. plus many other.... and about 1000hours.
material cost for one plane for one plane is 700-800€+ taxes. and this not include all above... for one plane i need to work 2 weeks all my free time. so for one plane 2500€ is very low price.... take your calculator... i promise i wont sell any planes under that. i rather
enjoy my spitty with Tero. im not mad, not going to work free.... [
