I spoke with the owners today abut bringing back the Bucker Jungmann and they were interested. If others call them we just might get something going. I am planning on scratch building another one for a back-up.

I spoke with the owners today and maybe if enough callers call in for the kits they might start making them available again.

FXD -> RE: Goldberg Bucker Jungmann (11/10/2006 2:34:59 PM)

If any one is interested i have one completed, never been flown,. done up like box cover. on scale of one to 10. it is a ten. will sell for 4$400 dollars. thanks fxd



Jim Clausen -> RE: Goldberg Bucker Jungmann (11/16/2006 12:15:52 AM)

After visiting GOldbergs facility, it is obvious that the Bunker Jungmann by Goldberg is gone forever. The are going into the ARF business because no one wants to build anymore.

I completed one of these last year with a 160FX and it is an excelllent power to weight combination, I did not have to add any weight at all and mounted the battery behind the lower wing trailing edge in the fuselage, I fly it with a Biela 18x8 and it has unlimited vertical, it will probably 3D but I did not build it for this reason, it weighed out right at 12lbs, not bad. With the extra power from the OS I will probably add smoke at a later time, it's a show stopper.



Flyrite -> RE: Goldberg Bucker Jungmann (12/20/2006 2:31:17 AM)

If anyone is interested I have one of these new in the box for sale, I won't give it away...... I will take the first $250.00 for it. You can call me at 214-649-0239. Joe Matussak

I Personally Think They Look Good And Love The Scale Color Scheme That Was On The Box Lid. I Have 1 I Am Recovering And 1 NIB. I Also Took The Plans To Work And Used Our Printer To Enlarge Them To 110" Wing Span. I Am Currently Enlarging A Cermark Pitts To 75" Span. Hope To Fly It With A 50cc But It May Take Up To A 75 To 80cc. Have TO Wait Till Spring To See. Love Those Bipes !!!!!

Do not expect the plans to be to scale as related to the kit parts. If you were to trace the plans you would not have parts that will assemble without some difficulty, but that is what modeling is about to some of us. I found this out when making this latest Bucker which required making a fuselage from scratch.
As you can see, I used the color scheme from the box but used yellow and insignia blue instead. I did this becasue I do not see white too well in the sky at times. I also used matching colors of PPG paints for the cowling and wheel pants.

bacplus -> RE: Goldberg Bucker Jungmann (2/22/2007 5:55:31 AM)

I have just acquired a set of plans for it , and through ignorance I was hoping for the REAL Bucker.....has anyone tried redrawing it to look lie the original inline Bucker? The Goldberg plans are nice but........I like the original version. Looks like a heck of a re-draw.

Aware Of That But Luckily I Have A NIB Kit That I Can Get Exact Templates From And Add Or Change Where It Needs It. Just Messing Around Actually When I Was Enlarging The Plans But Then It Seemed Like A Good Idea. I'll Have To See How The Enlarged Cermark Pitts Files First.



LuvBipes -> RE: Goldberg Bucker Jungmann (6/20/2008 6:01:27 PM)

I'm recovering and renovating my old CG Bucker. I'm going to swap the saito 150 instal (sold engine) for the newer OS 120AX.

I no longer have the plans or the manual. Can someone tell me what the recommended CG point is? Thx.



Azcat59 -> RE: Goldberg Bucker Jungmann (6/21/2008 1:24:46 AM)

Re: the Goldberg Bucker CG, it would take me a looooonnnng time to dig out the plans, and today is 113 in Phoenix, with my shop not too far behind. However.....I remember making a balance beam from a popsicle stick, which attached to the bottom of the front and rear aluminum wing struts, and I had a notch in it about 3/4" ahead of the rear strut bolt. One on each side of the fuselage, stick your fingers on the notch, and there she was, per the plans. Good place to start, and you could move it back a little bit if you think that is too nose heavy.

Why not just balance it off the top wing? I got bit by that procedure many years ago, and I have a theory that the further you are above the mid-fuselage CG, the more you get a pendulum effect, with any out of balance condition dampened. Engineers may argue with this concept and if so, they are probably right, but I will continue to wallow in my happy ignorance if so :-)

LuvBipes -> RE: Goldberg Bucker Jungmann (6/22/2008 9:24:59 AM)

3/4" ahead of rear strut bolt it is then. Thanks Clair.



mikesan152 -> RE: Goldberg Bucker Jungmann (9/23/2008 6:11:05 PM)

Greetings.

I have just received a Goldberg Jungmann kit. Do any of you happen to know of Bucker Jungmann building threads on this or another forum or group?



spike01249 -> RE: Goldberg Bucker Jungmann (12/30/2008 8:47:03 PM)

hi all more info can be got from here eg: CofG http://www.carlgoldbergproducts.com/discontinued/bucker.html

i hope this is helpful



Raysun -> RE: Goldberg Bucker Jungmann (1/4/2009 7:28:30 PM)

I have just aquired a Jungmann, fully built rtf less engine.

Will a 90 2s work out or do I need more motor? Any flying tips? I have bipe experience..Astro Hog, and am IMAC level (basic).

Thanks very much,

Ray

That depends on the weight of the model. Personally, I'd go with a minimum of a 1.20 4S. I still have mine (the finish is worn out and needs to be redone, it's 14 years old), and it's powered with a Saito 1.50. Mine is finished in fabric and paint and came out at 11.5 lbs. A little on the heavy side, but it flew outstanding and floated in on landings. Follow the setup guidelines from the link above as a starting point and then adjust to suit your flying style. It's an outstanding model, too bad Goldberg doesn't kit it any longer.

I bought one from a club member that has a .91 OS four stroke in it. From watching him fly it, your .91 two stroke should be just fine if you are just into sport flying as I am.

Azcat59 -> RE: Goldberg Bucker Jungmann (1/4/2009 11:29:46 PM)

Mine is about 14 years old now, and still flies well. I have a Webra 120 two cycle in it and the vertical is virtually unlimited. I used Monokote, and the plane is in the ten pound range (too lazy to go out into the shop and look it up in my log book). If you just want to tool around and not do anything too demanding, a 90 two cycle would fly it ok. I'd still go with at least a 108 or preferably a 120. They fly well with a 120 four stroke too. It is a great airplane, and a shame that kits are not still available.

Clair



Raysun -> RE: Goldberg Bucker Jungmann (1/5/2009 3:35:13 PM)

Thanks to everyone for replys! I think I'll go with a 1.20 2s as I do want unlimited vertical...I fly my old astro hog bipe with a .90 STigre and its a complete hoot to announce on the flight line ...."taking off from the left and going vertical"...showstopper every time. Something about a biplane...

Can't wait to fly the Jungmann, but mine is built so nicely I might just hang it up as artwork over the basement fireplace...
