Hi,

I recieved my FW-190 "Short Kit" from Dave Platt yesterday.
I will be posting the progress of the project here and at a later stage I will be creating a website to publish onto.

I am still waiting for my wood to get delivered from the supplier, but when I start I will post the progress here , any suggestions on the building part of the project.

AIRPLANE SECS:
Scale = 1:5
Wingspan = 79.25 "
Engine = Super Tigre G20/23 - 23cc engine
Retracts = Dave Platt Competition Retracts - Pneumatic
Servos = still to be decided JR/Futaba


Dave Platt Scale Extras
Pilot
Weapons Rack
Gun Kit
Cockpit Kit

This Plane is going to be finnished as a FW-190 flown by a Major Hermann Graff of the Luftwaffe in 1945

for more info please ask me.

Howdy Werhop,
What would be your thoughts (as you seem set on glow) on using a ST3250 - just thinking the additional weight may help.

Wurger

Excellent flying airplane...enjoy

WerHop

wurger : I bought this plane through my model supplier and he chatted to dave about the engine, and he is the one that advised me on the Super Tigre G20/23 23cc engine. I don't know too much about these big engines though, so I took his advice, He gives me very good ones.


F4u5 : Thanks , cannot wait for it to fly now.

The big Super Tigre engine require special fuel to run correctly. My friend, John Cole, who has used a Super Tigre 3000 for several years, cuts a gallon of Byron fuel (10% nitro 20% oil) with an equal amount of alcohol. This effectively reduces the nitro to 5% and the oil content to 10%.

This fuel mixture works extremely well. I've seen his models fly in temperatures ranging from +40F to +100F with no problems.

werhop have you considered a gaser. With high glue fuel prices running a ST3000 can become very expensive fast. a price list would be great to us give some idea how much this project would cost.

WerHop

Here is a rough prices for the project, as I come from South Africa I will give the prices in ZAR and in () the $ price +-.

I started by getting only certain parts that will be necessary at the start and am planning on getting other stuff like retracts at a later stage.

As I say before, I got my items through my supplier, so if you get it from Dave directly some parts may be cheaper, but the wood etc will cost the same.

Already Purchased:
Dave Platt Short Kit + Wood + Accessories = R5000 / +-$500
includes: 1:5 scale Pilot figure (exelent quality)
Gun Kit for front guns
Weapons Race underneath plane
Scale Static Prop (3 Bladed)
Cockpit Kit
Fibreglass Coul + Gun Hood
Scale Flying Spinner

Super Tigre G2300 Engine = R2300 / +- $230

Still Needed:
Dave Platt Pneumatic Retracts = +- R4000 / This price is a lot less if i does not get shipped to south africa, dave platt's website says = $299

All the servos and push rods/ control horns, etc - these will not cost too much for the project, servos most expensive.

One will still need glues and so of for the construction.

To add the prices up : R5000
R2300
R4000
-------------
R 11 300
-------------
This will still need the servos and pushrods, etc

This is a highly detailed and exact model, the parts is just excellent. I will be posting some pictures of the parts of the Short Kit later today, when i get the time to make them.


Please check out http://www.daveplattmodels.com / short kits / FW-190 to get all the prices from him directly.

Hi, Here is some photos of the items that comes in the short Kit from Dave Platt.

Some photos are a bit blurred, sorry about that!

Wulfman : Thanks for the advise, our supplier also told something similar to us regarding the fuel.

Remember that the fuel recommendation above is only for the large ST's (3000 up). The 2300 you have uses regular 10% nitro and 18% oil fuel. Not the low oil blend used for the big ST's.

Wulfman

My Feedback: (5)

WerHop,

No problem on the ST info. I'll ask my friend about the distinction between the 2300 and the 3000, and if the 2300 requires the same fuel mix.

Be sure and keep this thread updated with your progress. The Platt 190A is one of the few 190's I don't have (yet). I am very interested in hearing how you like it's construction.

WerHop

Thanks,

I will keep this thread updated and post some pics once the wood has arrived.

about the engine, i am not going to start it soon so I will find out about the right fuel mixture.

Here's about as much info on the 2300 you can use.
http://www.rcfaq.com/answers/engines/st2300.htm#AMC.
Ann Marie cross added this: Third, the engine MUST be fed high quality high oil (18%+, at least partially castor) fuel. It will run on FAI fuel but prefers nitro in the 5-25% range.

Werhop, I built my Platt Focke Wulf 190 A-4 in 1988 with a Super Tigre S-2500 for power weighting 12.5#, and with Platt main gears. It flew on that engine for 60+ hours of air time. The first ten were before all the clubs in my area went to a sound cap of 98db, those were the best flights. Muffled, that engine was the most cantaorus beast I ever owned, it would run about 5 minutes before the feul level would cause the engine to go lean so I had to add three clicks of mixture every minute until the end of the flight after the initial five Five years ago I had my Fw clocked by the local police and out of a shallow dive I was able to get 65mph, with out the dive the level max was closer to 60mph. Last year I replaced the S-2500 with a Moki 1.8 and have had over heating problems. So last winter I installed a duct to the head and with the weather we have had here I've run it on the ground at full power for over 5 min. With no over heating but have not been able to get in the air yet.
It is the best flying plane I have! My other giant scales are a Zerroli Corsair and Dynaflight PT-19 so that is saying a lot. I have converted the platt plans to a D-9 which I have just started to collect the hardwear for. Be carefull of side loading the gear, they will take allot of punishment but that 13.5 in strut is almost 1.5X the standard strut for a similar scale of any other WWII plane.
Things I've noticed about the kit:
- Have replaced the wing LE dowl once, and the mating hole elongated.
- It builds tail heavy with out the scale retractable tail wheel with it this problem is worse.

thanks for the info, I was waiting to get some response from someone who actually knows the design and plane performance.

Do you have a picture of your plane, so i can see the final product.

So does the S.T. 2300 make a huge noise?

thanks

Werner, The S-2500 was rated at 2.8 hp the G2300 is ratedat 3.7hp (I think). I did moment equation prior to starting mine and was able to quantify the amount of balsa that would be needed or the weight that needed to be taken out of the tail. By leaving off the retracting tail wheel, and reducing the thickness of the bulkheads and sheeting aft of the wing TE. That worked out very well, no ballast was added. As for power I nave seen G2300 in action but never flown one, I've seen it at pattern competitions in planes made for the YS 1.2 and 1.4. That puts it in the same category with the S-2500, TO SMALL! Get a Moki 1.8 Or a ZDZ 40 those engines will allow much more freedom in flight envelope.

Got to run
Joe
fly'em all and let god sort'em out.

WerHop

paladin: thanks for the advice, I have already bought the engine, but will test it and if it needs a bigger one i will put it on.

I need to get the servos for the plane soon, doo you recommend any for me?

did you get those scans working on the Graf yellow plane yet?

Werhop, I had to make sure I still had your E-mail address, you slipped my mind. I'll put that out to you tonight. If memory servse mecorrectly the first one I sent camback because It was to big to deliver. I've made some lower DPI scans and one of them sould get through. I'll send them tonight.

I have added pictures of mine on the ground to the members forum here on R/C universe. My main concern for you with a G-2300 is ballencing, the G-2300 it is considerably lighter than the S-2500 about 10oz (if memory serves me). This is a list of what I did to ballence mine without adding ballist:
- All bulkheads where 1/16 thick with four 1/8 X 1/64 marine ply stips going crossgrain, two on each side of the bulkhead.
- Removed sheeting from hori stab..
- Sheeted forward of wing TE with hard 1/16 balsa.
- sheeted entire fuse with 1/16 competition grade Balsa. This gives 1/8 thick balsa forward of the wing TE and 1/16 aft of it.
- Mounted engine servo in engine compartment.
- Mounted mixture control servo in engine compartment.
- Mounted onboard glow in engine compartment, this includes batteries.
- Mounted fixed Tail wheel, did not do retractable.
This yeilded a 12.5# plane after ballencing. With all these changes I am about 6-8oz heavier in the nose than I need to be which would allow me to add the stab sheeting and retractable tail wheel back on the next one, this one was just a test bed (that has lasted 15 years). But the paint aft of the CG would have to be countered with ballist in the engine compartment. As time went on I rebuilt the wing, spacificly the landing gear supports, to better handle the side loads this model sees when landing using lift vectoring.

If I can get a good day soon I plan to get my first flight with the moki and cowl inplace, to this point all flights with the moki have been without the cowl, looks terable!

I've included all this info. For your benifit, use it as you wish. I figure you will need to add 16-24 oz. To the nose of a built to plans model with a G-2300 for power, now that can be put in with a scale gun kit, cooling fins behind the spinner, etc..

Fly'em all and let god sort'em out.
Joe

thanks for all the advice, the email came through.

I was also thinking about the onboard glow system, can one buy these or must one make it yourself, it will make the plane better bacause I will not need a glow hole in the cowl.

I am planning to put all the extras into the plane so maybe it will balance out once completed.

thanks for all the advice

I hope you have as much fun with your's as I've had with mine.

Good Luck!

Werner,

I've got the Super Tigre G23 in my Chiltern Models Sea Fury. It is a little bit smaller than your Fw190 (183 cm) but heavier (8 kg). My guess is that they have similar performance.

The engine will fly the Sea Fury at scale like speeds but it needs 2/3 throttle to maintain level flight. Loops are OK but could be larger. I'm using a Mejzlic 18x6 prop and get 7500 rpm on the ground with 80/20 fuel (no nitro).

So, the engine will probably fly the Fw like European scale judges like to see it but not like American pilots would like to fly it .

And yes, it makes wonderful noise at full bore on the deck!

How about the O.S. 160?

BiteTheDust :

Thanks for the engine advice, to fly the fw scale, is this easy with the engine, the real fw went quite fast !
