Been thinking about getting one of these for awhile now. How long did it take between placing your order and receiving the kit? Did you order everything directly from CARF-Models?

I received mine in about 1 week. Ray Labonte is my selected Rep, and he keeps you informed on the status. I may have been lucky because there was a shipment on the way when I ordered. I ordered the plane, main gear, and spinner. Lazy Eight may have a better plan for the spinner and additional needed items. I will let him fill you in on the details. Lazy Eight, how long did you wait for your plane?

I can not tell you how good this plane looks. Photos do not do it justice. Even the size of the plane is not captured, nor is the extreme detail. Along with all the hardware, it also has scale lap seams molded into it.

Hello gents, I have had one in line for about 10 months now and have promised myself not to start it until my current project is complete.....which it is. I have the following accessories, carbon spinner, exhaust stacks and tailwheel all comp ARF genuine. 3W-85 xi for power and shindin retracts. I will run Hitec 5645mg Digital servos all round and J.R 2.4gz to control. I will be looking forward to others ideas and techniques to finish this baby. Im unsure of what scheme to copy but something with Invasion Stripes, gotta love Invasion Stripes. Cheers Trent.

So whats the deal with those raised head 'rivets' on the cowl/nose?? you would reckon they could get the dzus fastners looking a bit more accurate, otherwise on the money...

Warbirdrcer,

I too love the American Spitfire color schemes. Currently have Pica 88" with Moki 2.10 painted up as HL*K Fargo Express.

A must reference book is "American Spitfire- Camouflage and Markings. part 1." by Paul Ludwig and Malcolm Laird.
- Small picture of HL*HH on page 45 next to a P-51B with caption about Castel Volturno, March 1944

However, for a 1/2 page shot of same picture, HL*HH, see page 35 : "Fighter Command- American Fighters in Original WWII color by Jeffrey Ethell and Robert T Sand.
Best all around book I've bought in years. It has orig color pics of P-47, P-51, P-38, P-63, B-17, Focke-Wolfs, Me 262, lots of great nose art close-ups and many other acft/pilots in European theater. the back flap said Bob Sand took his Camera and Kodachrome film when he shipped out in 1943. He was in the propeller shop and later a P-51 crew member. Awesome photos.

my CMP Spitfire is waiting for more funds. I have the Sierra gear and they are beautiful. I'm waiting until I can fund the 3w-85 Competition engine (red head with two spark plugs) before I start mine. Maybe 2012.

Concure on the raised rivet heads. I like the dremel idea.
I'll be watching your progress with envy!!

Mike P.

That looks better, damn shame though they could not have taken the time to mould in the correct size/scale dzus fasteners, it's not rocket science to get them looking right when producing such a detailed plug/mould. Theres a bit of work getting them to look right though for us modellers.... That being said Iam so close to placing an order for one.

For my 1/5 scale Pica cowl (plastic) i made Dzus fasteners look ok with following:

1. I heated up with a butane lighter (for the fireplace) a small washer while holding it on the edges between the needle nose pliers.
2. once hot, and black from the soot, I placed where a Dzus fastener should go. This did a shallow burn into the plastic and look conving enough.
3. I had planned to go back and add the horizontal slot with a heated up flat blade screwdriver, but never did.


I will try to find my pics of a real Spitfire Mk-IX here in VA Beach.

Tobbe,

The raised heads removed on your ship look good. Could you post a few close-up shots of individual fastener that have modified? Also it appears you sanded the fuselage bond-lines smooth. How did this work for you, I was thinking of the same thing.

Firebee,

Thanks for the museum link. The Spitfire photos in hanger 2 will be helpful in the future.

Dang this thread is taking off! My DA 85 should be here this week then I can start the engine fit up. I like the idea of sanding down the cowl fasteners. They are way to big. Thanks for pointing out a simple way to make it look better. Over all it is a great looking plane right out of the box. I'm still on the fencewith the exhaust. The can setup looks like it could be trouble down the road with heat build up. I have run them on my Big Aerobats but looking scale was not a big deal so large air holes on the bottom is normal fare in that game but not here. I think a1.5" prop spacer and the tight fit pitts muffler may be the way to go. Any help here is welcome.

Sorry for the late reply WARBIRDRCER. I started kicking the tires around Dec. Then jumped on it right after X-mas so about three weeks after I placed the order. Ray is my rep as well I think me and WARBIRDRCER had our planes in the same shipment because we got them the same week. I,m getting my landing gear and wheelsfrom Sierra. I,m going to run a TruTurn spinner they have one for the 100" Ziroli spit they are the same Dia. 5.5" Ziroli also has some cool inner gear door covers and trim tab acuators and fairings plus the Mark 5 three stackexhuast kit. I'm still looking for more stuff and will post as I find it. Ray said that Dynamic Balsa is making a cockpit kit for it. I'm just finishing my Top Flight P-47 built from the kit. So this weekend I will be starting the Spit.

I have had a few Spitty's also Mustangs, Hurri's over the years and have a few useful tips for those interested. The issue's thats worth evaluating for any size Spitty are engine options and suggested cooling methods. First of all the Spit is tail heavy by design due to the short nose moment.... So a heavy/large engine is worth considering to save on dead weight which is going to be inevitable anyway. Fitting it all inside the cowl is the ideal plan as well. Some of the inline twin cylinder engines would ideally be my solution so as to lower head hight thus keeping engine inside the cowl. Ive noticed some new larger 4 stroke engines recently starting to crop up and cost aside would be one way to go. Cooling well thats always fun on the Spitty but not an issue really with some planning. Engine cooling - My rule of thumb should be 3/1 three times the hot air exit area to cooling air entry, also I use close ducting to direct airflow closely around cylinder heads. Use the open exhaust outlets to assist with dissipating hot air plus non scale holes in rear base of cowl. As long as you get the hot air out and avoid its build up you are right. Sounds pretty obvious but so many people come to grief when engine cooling is not done correctly.

These new 4 strokes engines have me intrigued and might be the selling point for me to do another Spitty like this one...

I love the Comp ARF planes, doing a Mustang at the moment, and the Spit has of course caught my eye.
I will be interested in seeing your engine set up. DA 85 seems to be the way to go, with a slimline pitts muffler, thats what I am thinking anyway.
Look forward to following your thread

Well after talking with Derrall at Sierra he has the two different Spitfire spinners one may need for you Spit. There made from Aluminum and weight around 14oz. One is the short nose for the Mark 5 and below and then he has the long pointed one for the mark 9 and above. Plus he has the wheels for3 spoke 4 spoke and the hart shaped 5 spoke. I should have eveything here by Friday and will post pictuers of the gear. Hope this weekend I can start the build. I picked my Pilot and colors. I'm doing the Pisanos US Spitfire.

Ok Here is the start of my Spit. I got my engine today but my gear has not showed up yet. I started to fit the engine to the fuse. I will be using a 1.5" prop extension to get it all in there. I have found the stock Slimline pitts muffler is to bulky and would require the cutting of the cowl. So I'm looking at a Jtec compact muffler instead. Here are some pics of what I have done this afternoon. Not much but its a start. I will be glueing togather two 1/4" plywood plates for the fire wall and glueing them behind the fiberglass firewall. This will add weight and mass to soke up the 85's vibrations. I found a good DA 85 Template on the web at Hobbico. http://manuals.hobbico.com/gpm/gpma1286-manual.pdf its on the next to last page.

Revised after improper photo posted 1-29-2011. Thanks Brad.

Lazy Eight,
Great work on the DA-85 mounting endeavor. Looks as if you have the answer I have been seeking, and now I can purchase the Powerplant I was hoping could be used on this airframe. Also keep me informed on the exhaust situation too.

Since I purchased my main gear through CARF, and do not have my Powerplant, I decided to start with the wing assemblies. I wish I could report progress, however I am held up with what could be an improperly designed main gear or main gear mounts in the wing. Whatever the cause, there is a geometry issue here. I have a few thoughts on this matter, but will need to regroup and see what idea will work best before continuing on. Maybe someone has already come up with a fix, and if so I am all ears.

Lazy Eight, do you know if there is a difference between the Sierra and CARF Spitfire main retracts? If so, it will be interesting to see if your Sierra gear fits and functions without fouling in the wells and strut cutout edges. Please see photo.

Okay,

The 1st photo shows the gear placed in the stock position: As you can see, it would require you to trim the FWD corner of the wheel well opening, and make adjustments to the outboard main gear mount assembly. This still however leaves the axel out of proper alignment. The wheel and tire shown is a 5 ½” Byron for testing only.

The 2nd photo is a close-up of the wheel in the well. Photo 3 shows the wheel and tire aligned with the axel location.

Photo 4 shows the upper portion of the strut pulled down 070” out of the strut mount from the retract mechanism. Doing this centered the axel and allowed a slit twisting of the lower strut assembly to allow for proper extension. Photo 5 is pointing out the relocation of the strut at it’s attach point.

Photos 6 & 7 show landing gear extended with strut in the modified position. This is without the machined extension/adapter.

Okay, it is off to the machine shop for an adapter to be fabricated to see if extending the strut will allow proper location and extension without modifying the scale outline of this fine aircraft.

Warbirdrcer, just one little note before you go too far and start cutting anything to get clearance for your gear, make sure you have the scissors of the gear legs pointing forwards. In your picture the one you show is backwards.

Good luck with your build.

Brad your right the Scissors go forward. I have heard there is a little offset from the gear to the wheel well. COMP ARF knows about this but has done nothing to fix it. Talk to Ray before going any further. I think its somthing we will have to live with but it may take a little tweeking at the mount rails. Read the other build thread I think they talk about this in that build. As far as I know the Gear that COMP ARF is selling is Sierra Gear. The tail gear Comp Arf has is there own and is plastic,but the mains are Sierra gear. Well I have been hacking away at my Slimline muffler and have come to the realazation that its a no go without cutting a hole in the cowl. I cut the muffler to make clearance but it still is to thick at the header. It's 1.250" And that's a 1/4" to much. I could buzz the header down then weld all the ends back on but after paying my welder I can buy the Jtec that is 1" at the header and should do the trick. I know some of you guys might say why did I cut up the muffler well why not try and see if I could make it work. I still can weld the ends back on and maybe it will work on a P-51? Anyway here is the pics of what I'm working on. I have cut out the fire wall and notched it for a 2" muffer that will coming this week, the "Jtec pitts". I used 1/4" ply on everything. Overkill yes but much needed weight up front. I doubled the firewall so its 1/2 thick. The wood that came in the kit is way to light for me with a DA 85. These engines shake more that the 50 cc engines so more lumber it is. I will be tristocking the notch line then using West epoxy thickened up too make fillets all around everything then glass cloth ontop of that to stiffin the hole thing up. More pics to come after all the gluing. "Built like a tank you say"

Great photos of gear misalinment. I asked Ray about this before I bought my kit and he said the gear is set in the rails for scale stance. They did not change the wheel well opening and leftit up to us I guess. Bunch of crap. But it can be over come. I still would call him Ray that is. Let me know what he tells you. Time to mix up some epoxy!!

WOW if it works I'll buy a set too!! Please let me know. I will call Sierra in the morning and talk to them about this he may have a solution or can make one! I think 1" would be even better it would center the gear on the mounts too. I wonder if it will mess up the stance much??

Revised after improper photo posted 1-29-2011. Thanks Brad.

Lazy Eight,
Great work on the DA-85 mounting endeavor. Looks as if you have the answer I have been seeking, and now I can purchase the Powerplant I was hoping could be used on this airframe. Also keep me informed on the exhaust situation too.

Since I purchased my main gear through CARF, and do not have my Powerplant, I decided to start with the wing assemblies. I wish I could report progress, however I am held up with what could be an improperly designed main gear or main gear mounts in the wing. Whatever the cause, there is a geometry issue here. I have a few thoughts on this matter, but will need to regroup and see what idea will work best before continuing on. Maybe someone has already come up with a fix, and if so I am all ears.

Lazy Eight, do you know if there is a difference between the Sierra and CARF Spitfire main retracts? If so, it will be interesting to see if your Sierra gear fits and functions without fouling in the wells and strut cutout edges. Please see photo.

Okay,

The 1st photo shows the gear placed in the stock position: As you can see, it would require you to trim the FWD corner of the wheel well opening, and make adjustments to the outboard main gear mount assembly. This still however leaves the axel out of proper alignment. The wheel and tire shown is a 5 ½” Byron for testing only.

The 2nd photo is a close-up of the wheel in the well. Photo 3 shows the wheel and tire aligned with the axel location.

Photo 4 shows the upper portion of the strut pulled down 070” out of the strut mount from the retract mechanism. Doing this centered the axel and allowed a slit twisting of the lower strut assembly to allow for proper extension. Photo 5 is pointing out the relocation of the strut at it’s attach point.

Photos 6 & 7 show landing gear extended with strut in the modified position. This is without the machined extension/adapter.

Okay, it is off to the machine shop for an adapter to be fabricated to see if extending the strut will allow proper location and extension without modifying the scale outline of this fine aircraft.

Just sent E-mail to Darrell at Sierra maybe we can have somthing made up to fix this little problem. Maybe 1/4 scale gear legs is the way to go?
