The Sierra retracts have arrived, balsa and plywood should be arriving soon and the plans plus the cowl and canopy I already have. I'm putting my other build on a temporary hold. A couple other guys in our club are also build this plane so it looks like the German Luftwaffe will rule over our field for awhile.

I'm am planning on recreating the A8/R2 version.

I like to do the tail first. I'm using 4-6 lbs balsa to try and keep the tail light The rear spar on the stab is made of laminating 1/8 balsa between 1/32" plywood. This makes for a strong spar the holds it shape and doesn't warp.

I would recommend sheeting the entire tail with 1/16 balsa, and carve out as much balsa as you can for the back decking. This 113 inch FW is an end result of one I had built years age. I have the original gear from Darrell. The plane got so much attention, that people were asking for a FW this size, resulting in Roy re-doing the plans. Origianlly, Darrell was doing the cowl. The plane flew OK, but mine came out heavy. Mine weighed 56 pounds, and had 5 pounds of lead in the nose. Antoher suggestion is to beef up the outboard rib , foward side, that carries the gear rail. Any hard landing will tear the rib due to the small amount of material left on the thop side. I broke mine 4 times, even after I had doubled with with a 3/16 ply doubler....and I never really hit that hard in any landing. I would recommend bolting/bonding a piece of aluminum on that rib to help brace it. These are just my opinions. Best of luck.

Thanks for the comments Jeff. It's must appreciated.

I'm sheeting the stab with contest grade 3/32 balsa which is very light. I cut out the top elevator with an exacto knife[:@]from 1/16 ply but it still seems heavy so I'm planning on changing it to a center peice of balsa with ribs built up on top and bottom with a 1/32" cover.

At the moment I'm planing on building the A-8/r-2 "Black 8" flown by Willi Maximowitz.

I actually used 1/64 ply....a lot of work carving out that deatail

I did Heinz Baer's Red 13

I may do another one someday....heck I have the gear and Glennis wheels.....

I was thinking about using 1/64th but the hobby shop had a 12x24 inch sheet for 21 dollars. Thats just more then I want to pay for it.
Stab is build except for the tips. Wish I had a scale as it's very light.

Crap thats exactly the Fw 190 I was planning on doing with my Jack Devine kit. I have the fuse and wings all sheeted, but was waiting for retracts


I have a few war time pictures of it too.

Time to find another plane.

You can do the same one EM, I won't tell.

Evil, you sure have a lot of planes being built. Do you have any finished? Fokker DVII maybe?

Evil_Merlin

My Feedback: (13)

The Fokker is nearly done. Just need to cover the wings. Got some great printed fabric from Wildmann Graphix, in the early 4 colour style.

I also have a Pica T-28, and a few othe little birds completed.

Does anybody know of a source for a somewhat scale three bladed prop for this plane and engine combo?? I'm planning on using the RCS 250 radial .... I hope.... Looking into a 28 to 30 inch with about a 14 - 16 pitch thats looks like it belongs on the 190 with it's wide blades.

Dave

Aircraft International carries Biela Carbon propellers which are beautiful. The 250 radial should be able to swing a 32-14 3-blade and you can order the biela's in black with yellow tips.... They are really nice!

wingspar

My Feedback: (3)

Thanks for the tip reefer. They do look nice but I'm looking for, if any are around, scale looking Focke wolf prop blades. I think Solo made some for awhile but there gone now.

Port elevator is just about done. Just need to do the top and bottom cover. I've got 1/32 balsa for it but might crack down and do it in 1/64th plywood.

Control horn is made with 3/16'" music wire with a brass horn and wheel colar silver soldered to it.

Hi, i have a 100inch 190 that i converted to a TA 152 with the longer nose to overcome the balance problem, i also went with music wire and the brass horn with one servo, but changed it to 1 servo each side for redundancy. at the moment i am in the process of flight certification.
I am testing mine without any finish detail and with a 3W85 comes in at about 42 Pound.

dubs, is it a kit or a plan and which one? Post a picture if you can.

I know that ImpScale offers a big Ta 152 as well.

I have the Dave Andersen TA 152 plans and am waiting for PCK to list their pricing on the kit. Great looking plane.

Evil_Merlin

My Feedback: (13)

grimmace, looking in my email from last year, I was quoted 475.00 for the kit. I'm sure its a bit more now.

Ran into some problems[:@] First I installed the hinges at what I thought was the hinge line. To make the elevator have enough travel I have to cut alot out of the top and bottom and even with hinge covers installed on the stab there would be quite a gap. Then looking at the tip of the elevator it's just FAT compared to the real plane.

Thus I've deceided to throw it all away and start again. But this time I'm going to my ComuFoil program and redraw the stab ribs to reflect more of the original. I will be using 2410 at the root and 2408 at the tip. this should improved it alot.

Hi Dave., i bought it as a started project at a club sale evening but not from the original builder, what there was of it was very well built but there was no flight engineering in it. By the look of it it was built from a plan, and i have taken 18 months to get it to its maiden flight last Sunday, at 100 inch span it is a very big aircraft the fuselage is 7 feet 10 inches long and put together only fits in one place at home and is very difficult to move about without crashing into things.
I had to redesign the retracks and put in 2 complete retract air systems 1 for each side as the arms and wheels are so heavy a normal system could not cope.
my system runs from 120 pound down, thats another problem to get everything airtight at that pressure, i used 2 Robart veria valves fully opened as they give more air on opening then the normal valves, i lengthen the nose by about 4 inches (TA152) to get the balance it flies fine without any extra weight in the nose, i have built in a bomb release, parachute release and a smoke system,it has 12 servo's 3 batteries Smart-fly power system with Futaba 12 channel 2.4 gig.That was another problem to learn how to program the 12 channel radio, i have been flying Futaba for 32 years and the instruction book is a joke, it beat me,i managed to sought it out from the other guys in the club.(W.R.C.S) who had that radio.My main build problem was redesigning the retracks but i see you have bought a Serra system, that will solve a lot of problems.
The maiden flight was interesting! my take off was ok but i could not stop shaking trimming out was a few clicks to the right i did all the requirements for certification and at the end of the flight i thought i would give it the gun past the pits, from about 300 feet 45 degree dive the engine wound up to an amazing sound (terrifying) at about 20 feet high level with me and half way down the runaway going upwind with the prop a 27X10 screaming the engine stopped i had run out of fuel, just what i needed after 18 months work i had a 24 oz. tank in it, there was no room or height to turn so i carried on and landed in the bush.When i found it i could not believe my luck practically no damage even the prop was ok. At 42 LB when that hits it normally tears itself to bits with the momentum, the rudder hinges had broken and one wing tip was stuffed but a few hours work and its ready again for another try at certification. Oh yes i have now fitted a 32oz tank. Have a look at the club web site wrcs.org.au

dubs, thanks for sharing. It's looking great! How much washout if any do you have in the wings??

Have the new stab ribs drawn and imported into my CAD program. Ready to start on stab, version 2.0

Hi Dave the wings have 2 degrees and additionally the ailerons are both slightly in the up position.
