The Brodak kits are VERY close copies of the Goldberg kits. The box art is the same and the plans are the same blue line art drawings.
I actually bought one at a hobby shop that I knew had a lot of old stock items thinking that it was an original CG kit. It wasn't until I got it home that I realized it was the brodak kit, which was fine. Unlike my 3 other Brodak kits, the Bean didn't say Brodak on the outside.

One thing I intend to change though is the firwall mount. The kit uses a plastic mount but mine will have the balsa fairing blocks and the landing gear placement as on the original. It's just not a Li'l Jumpin' Bean without it.

It's almost silly to say it, but Ibought my first "Bean" because of those balsa cheek blocks. Ithought it made the plane look som much more "cool" than the Baby Ringmaster with the clunky metal bolted mounts.

In a way it does sound silly but truth be told the box art really did do a lot towards selling the product.

When I compared those two features, my consideration was how universal that hadware was and while not nearly as good looking, it was reusable so that I could nore easily build another model from scratch and not have to buy as much hardware to get into the air!
Also not looking quite as cool but more practical was the Wizard's firewall with the break a way feature which to my mind was more durable if not kind of hokey looking with the rubber bands.

So for me it was practical, for you it was aesthetic. for someone else who knows what but the box art is/was very important if you picked out the kit yourself.

It's true I have more of an aesthetic view. Also one of the reasons I loved the semi-scale stunters and planes that looked like their real or "possible" counterparts. Ido admit to having more than a few batches of practical hardware on hand for engineering and try to to blend the engineering with the look; the difference between a Tupolev ANT-6 heavy bomber and a B-17 for example.

I bought a Bradak kit of the Goldberg Lil Wizard a few weeks ago. The nose has been redesigned to accomodate beam mount engines like a TD or Norvel. No plastic engine mount here. The engine bearers are good solid hardwood. The wasp .061 engine, which is a beam mount engine, is currently enjoying a bit of popularity among 1/2a controlline flyers. Also, both versions of the Brodak .049 as well as the Brodak .061 are beam mount engines.

Here is a Carl Goldberg "Lil Wizaed" my grandson built & is learning to fly C/L on. He built the plane & painted it, I helped put the trim colors on. He is 10 years old & is learning how to build, so we started with something simple. Brodak dope....Gene

That plane was designed for an engine within the power range of a Babe Bee. Assuming your Wasp or NORVEL are the RC versions, I would suggest you run them with the throttle partly closed to get the power down.

IMHO both the TD and NORVEL (CL version) are too powerful. I do not yet have the Brodak engines you mention so I can not comment on them.

Good luck with it.

If you want plans, there's a version of the Stuntman 23 called the "Stunt Chimp". The link to the free plans is here:

Default RE: Carl Goldberg's 1/2A C/L's

I built several of the goldberg c/l kits as a kid.

The first was a lil' jumpin' bean (LJB) that I did a crappy job on. I later built another and it was probably the best job I ever did on a c/l model. Crashed it to splinters when I failed to pull out of a wingover flying of blacktop.

In a fit of nostalga I bought a brodak kit. I haven't built it yet (just came in mail last night) but opened the box and looked it over. It is not really the same kit at all, some ways better, some ways a little dissapointing:

-The laser cutting is NICE. I have been out of the hobby for a decade or so, and this is my first laser cut kit. WOW! I don't miss the half-way and still crushed die cutting at all. Downside is it looks like a couple of parts fell out of one sheet before they got into the box. Reinforcement for the center of LE and TE I think...they are simple and there is plenty enough scrap to cut new ones from.

-TheoriginalLJB used self jigging ribs. The ribs had tabs that supported them that you broke off after the wing was built. The Brodak kit comes with four jig blocks to support the leading and trailing edges. The Brodak way probably works better with laser cutting, as the old way depended on you being able to leave the jig tabs attached to ribs even though they were die cut.

-Theoriginalhad a plastic canopy, and a little balsa half pilot (with a yellow shirt and red baseball cap IIRC) you put decals on. The Brodak kit has a canopy shaped hump on the balsa fuse...this is probably the biggest issue I have with the kit....I think it changes the character of the model a lot, but since I haven't built it yet, maybe I will be fine with it.

-The origional had a plywood firewall with balsa blocking support. The brodak kit is beam mounts by default, but it includes a plastic T bracket for tank mount engines. The origional had the firewall pretty much on the LE, but you'd have to cut wing clearance in the T bracket to do that. If you know how the origional was, it wouldn't be hard to cut a plywood firewall and blocking to get back to that.

-TheoriginalLE had a groove down the backside that locked it to the ribs vertically, no need with the brodak jig blocks and CA, but maybe a little heavier. Also, the old way could make the ribs stand proud of LE on one side or the other because the die cut ribs didn't have the locating tab in exactly the right place, and the afformentiond groove could be a little off center. Fixing this before gluing the LE on was one thing that made my second LJB much better. Overall, win for Brodak.

-The origional had eliptical wingtips that were laminated from two layers of 1/16" balsa, with non-overlapping joints. This allowed the grain to follow the curve. The brodak tips are one piece of 1/8", so the area near the LE has the grain running chordwise instead of span wise. It looks to be good wood, but I think ol' CG had a better idea.

-Origional had you use scrap from the canopy as leadout eyes, Brodak supplies wire and grommets, win brodak.


-The CG kit had a tailwheel, the Brodak uses a skid.

-Brodak kit has real plans plotted from CAD and an instruction book. Origional had plan only for wing build (no rib patterns even) and hand drawn isometric instructions on the same sheet. The brodak plans are nice, but I kind of miss the vintage instructions, flying tips etc.



Stuff that is the same as I recall:
-Except for the afformentioned canopy and firewall issues, it is recognizably the same airplane with the same nice lines. I think starting out with the LJB is part of the reason I like the lines of a Globe Swift so much, but maybe not, because I know of no pilot that finds the GS ugly.


-Preformed LG, with rubber band holding it forward...the Brodak kit is a LITTLE bit different, but maybe better.

-Cloth hinge material. included.

-The Brodak kit still includes tissue covering, but maybe a little better grade than the old kits came with...that would be good, because the old stuff was pretty delicate. I think I will use mica-film regardless.

-Brodak kit includes decals that are exactly as I recall from the origional. I don't have the kit here, and I didn't notice if the pilot decal was there.




So those are my impressions. What is the state of the art in fuel proof paint/dope for 1/2A models these days?

CajunAce,

Can't really tell by the pic, did the firewall delaminate or come loose?

First thought was, forgot to double-cement. Second thought was, lite-ply?

Nice looking Lil' Satan!

I built a number of those little Goldberg kits when I was a kid but can't remember which ones. That was 53 - 54 years ago. I loved those things. They were simple to build, flew great and were tough as nails. I have no idea what happened to any of them. I don't remember crashing any of them but I had a few very hard landings.

Yeah, I miss these things as well. Not the same as the one I had in the late 60's. I am however modifying mine so it will have the ply firewall and blocking support. Oh, and the old style landing gear mounting.

They must have changed it since I bought mine last summer. Mine has the old combined plan/build instructions/tips. The picture on the box and the plan both depict the way the old LJB looked, including the plastic canopy, firewall arangement and laminated wingtips, even though the kit isn't like that. Maybe there was a copyright infringement. I also fly rockets and Semroc (and some others) make reproductions of several of the old designs, and they require you to go to a site that has info on them and download the instructions because they don't want to have to deal with copyright hassles, even though Estes doesn't produce the kits anymore.

I need to get back to mine. I have the wing framed up and the tail feathers assembled, just need to finish it off. I don't remember how the old one flew, hopefully the new one flies good. I also have a Brodak Baby Flite Streak that I haven't started and I'm currently flying a Brodak P-51 and a Brodak Original Flite Streak with a Fox .35 Stunt. Having a blast with that one!

I think we've all done that at one time or another. CA can also make a field repair very temporary if nitro methane gets on it.

George seems hard to contact lately and someone said he is rebuilding houses from Katrina.
If you leave him a message He should call back.

Nice guy that never defected to R/C like most of us.

Just picked up vintage NIB Goldberg kit for the lil' Jumpin' Bean on that auction site  for less than I gave for the Brodak reproduction.  

Think I will build them both, and build the Brodak kit with the beam mounting, and either a tee-dee or an AP 061. 

The vintage 'Bean will get the same Black Widow that flew my last one 30+ years ago.  

fizzwater2: The origional came with more of an instruction sheet than plans.  There was a plan view to build the wing over, but no rib or other patterns at all...just isometric step by step drawings showing what to do with all the die cut parts.  The Brodak kit comes with complete plans, but I'm not sure it would match the origional close enough to use for repair after a crash.
