Hi pencon, realy great result with this MiG 21 !!!

About the exhaust, we must to talk :) when I finish the projekt will talk :)

Thanks man !

Cheers

Thanks coming from you that is a complement . I've subscribed to your awesome FW build , and if anything it looks even more amazing sofar than your BF109 ..

The Bf-109 projekt is a great , here you can see my video

<span style="color: rgb(0, 36, 74); font-family: Verdana, Arial, Helvetica, sans-serif;"> https://www.youtube.com/watch?v=Cnb_LGbyq78 I LOVE THIS AIRPLANE :)



I wander does anyone know what is the difference between FW-A8 -9 and FW-190 D wing ???? I cant find any information about differencees ( if have ) And other , the differences between Horisontal stab of A8 version and D9 ???

PS: I have some ideas . ;)

Thanks in advance

Ceehs

I don't believe there was any difference in the wing. Have to double check my books to be sure. But actually, I think Kurt was going for the whole enchilada with the Ta152, however because the extended wing wasn't ready yet and the modified fuselage/new engine was, the high brass pressed him into going with what he had as an interim solution. They desperately needed fighters (and pilots)!

No difference in the wings and H. Stab between the A/F and the D model 190's. The changes came about with the TA152C and H

The Dora and Ta152 fuselage mods are both different from each other due to different engine configurations and the wing on the Ta152's being moved forward on the fuselage.

Great to see you at it again!!!

Thanks guys, yes I know the differences between versions after D ( Dora)
I wanted to know about A version but I find all information, Have differences in engine( nose) section, vertical stab ( D is longer) several details around cockpit , the longer fuse , several details in the wings , especially around guns, some hoods, and little different canopy

Hi guys , here some progress of short fuse of A8 :

Rumen, if you are producing exhaust stacks for the D9, I am most interested in buying a pair.

http://www.rcuniverse.com/forum/atta...mentid=2015824

And, if you are making the blown canopy, I am interested, too!

Yes I will make exhaust stacks for sure , about the blown canopy I don't know , baybe first I will make the latest version and then I will see, I have so much work ....

Regards

Okay Rumen ! Jose says he can make the blown canopy for me now. So it is the exhaust stacks then.

Remember it is the Jumo stacks, not Mercedes Benz. As you can see from the picture, they are quite wide and prominent.

I am using the Sist D9 without stacks now, and it is a bit embarrasing ; You can see straight through the plane !! :D

Jose have the blown canopy ( if I don't make mistake) for his Ta

D-9 and D-11 , D 13 are with Jumo , so I will make it

The Ta-152 have DB 603 G engine ( and Jumo 213 A-C) , but his sticks are to different

Hi all , here some progress on A8

http://imagizer.imageshack.us/v2/800...911/F5Dir0.jpg

I was just wondering how this one is going. Last I looked, you wasn't quite done with the Dora.

Hi perttime ,sorry for the delayed response !

I want to finish with the A8 fuselage and then I will start with the wings wich are the same with the Dora's

Here is my progress with the A8 fuse and ribs

http://imagizer.imageshack.us/v2/800...661/e7GYKG.jpg

Hi , I have a big progress with the A8 fuselage but I'll post only two pictures, when I finish all work I will post more

I wonder what skale to cut for the first time, I make wto variants of plan in 1/5 and 1/4 scale ?

Hi guys , I am allmost ready with the A8 fuselage :)

http://imagizer.imageshack.us/v2/800...661/vxgjR0.jpg


http://imagizer.imageshack.us/v2/800...538/IzbNpz.jpg

I want one...

No problem , what scale you want , maybe 1/4 ?

Now I will make the wngs ( the work is faster) then I will cut the model for me , for tests in 1/4 scale. Then I will make cowl , gun canopy , and I wonder how to make the cockpit canopy , maybe from wood , I don't know yet .

Looks great fokke!!

It would be very impressive in 1/4 scale!

thanks

dave

1/4 scale.

Thanks Dave !

I made the airfoils of original wings in the root NACA 23015 and NACA 23009 in the tip of wing
So the wing will have the original foil , What you think about this my decision ?

When I made a wing for a smaller 1/7 FW 190 I considered the Selig airfoil and added a slight washout to improve slow speed handling. Using Compufoil you can see the aoa and estimated stall speed. So by overlapping the aoa range between the root foil and the tip foil I was able to add very little washout while prolonging the stall.

Since your thinking of using the actual scale airfoil be sure the retract mechanics fit the airfoil because usually the model wings are slightly thicker than scale. Maybe at 1/4 scale this isnt a problem, I dont know, just something to consider.

Ni Chris , the original airfoil is enough "fat"for landing ger , so I do not see problem to use it for my projekt:)

Thanks for your post

I made 11 wing ribs from NACA 23015 to the tip in NACA 23009 and putthe angle 2 degrees . My program can't make different angle between root rib and tip rib.....


This is the result:

And ribs in the wing

http://imagizer.imageshack.us/v2/800...674/Bm7TTi.jpg

Look up Compufoil. It will create the ribs for you then you can proceed from there.

http://www.compufoil.com/index.shtml

My concern for your wing is the AOA of the tip foil and the stall character of the plane. Look up the stall info of the tip foil your using to see what the neutral range is and what the stall angle is. A very small washout adjustment within the neutral range will help the stall performance without making the wing look funny.

Thank you very much Chris, I can't understand all your post but I made the correction and now the root is +2 degree and the tip foil is zero dergrees as the original :)

I will check Compufoil thank you !!!

I made the all ribs with the correct angles. Now I can start to build the wing :)

http://imagizer.imageshack.us/v2/800...633/QIkNCO.jpg

Good work Mr fokke.

What Chris is saying is to just make sure you build a little bit of 'washout' into the wing tip for better low speed (higher angle of attack) flying so the tip does not stall before the rest of the wing.

Great model and workmanship mate.

Brad

The full size has 3 deg washout anyway so why not just copy that? I'm guessing they knew what they were doing, and it wouldn't be 'scale' with anything different...
Evan, WB #12

Hi guys,
Brad ,that's is what I made . I made the 'washout" , in the root is +2 degrees , then in the tip is zero. This modification is not only for better low speed , this I made and for better work of ailerons in up position, because if we don't have washout in this area the aileron will work good only in down position!

Evan , on the original the angle in the root is +2 degree , I use factory drawings and germany documents about this , my information is this :)

I put the drawing of Sierra landing gear it to the plans, so I made position . I choose Sierra because that are strong and are 1/5 and 1/4 scale gears

http://imagizer.imageshack.us/v2/800...746/ukPIB5.jpg

yes, good choice. Sierras are very strong gear. Can't go wrong with them so long as you can get your hands on Darryl to order them!

thanks

dave

All good mate, just making sure our language barriers are being bridged haha :cool:

Brad

Guys , can you help me with two dimensions of FW-190 Sierra gears in 1/5 and 1/4 . I need to know the lenght and the height of the main plate of gear ?

Thanks in advance

Some progrss with the gear

HI
I start to make the wing ribs of the wing, I use for more reality the real plans of the A5 . Off course I have more work on the ribs and make stringer holes .
