Brodak/Goldberg 1/2A kits
« on: November 22, 2010, 11:28:04 AM »
 Are all of the Brodak/Goldberg 1/2A kits laser cut? I keep thinking about a 'Lil Jumpin Bean. Had one with a Tee Dee .051 when I was a kid and remember having a lot of fun with that one. y1

Tee dee sounds like a lot of power for the bean.

Lazer cut, yes...but the engine mount is is a lame piece of plastic. The canopy is wood, unlike the original plastic vacu formed piece.  I cut a ply firewall and nose block pieces to replicate the original as shown on the box art.  It is a decent kit, but would be nicer if it had the original design engine mount and plastic canopy.

That "lame piece of plastic" happens to be tough as nails.  I have one on a Plastic Fantastic 24 that has been crashed, literally, dozens of times.  No cracks, nothing.

The "lame piece of plastic" will also allow the builder to block the left side of nose with balsa and cover the protrusions on the right side to make a nice flat spot for a wedge tank. I would modify the new edition though to include a longer nose to allow modeller to do beam mounts with a ply sandwich over two slivers of maple or radial mounted tankless engines. Golden Bee users could just saw it off to original design length.

A 115%-120% scale up of this model would be nice for hotter .049s-.061s

Hi Victor,

I do believe that you could splice the beam mount nose onto the kit fuselage without much problem.  With the ply doublers extending back over the wing root, all the splices would be covered by the ply, and with modern epoxy, it would be pretty strong and not much added weight at all.  Since the original Goldberg was for firewall mounted .049s, I doubt they even considered it when Brodak did the "new" kit.  I would like a clear canopy too, myself. y1

I had one in 1964, and my son had one years ago.  it still lives in the basement!

The picture on the Brodak website shows that the Jumpin Bean is now beam mount. I have an original Golgberg Bean with a Cox Blackwidow on it. I flew it last summer along with my Sig Skray on one of the rare non windy days, I forgot how much fun the 1/2A's are and how twitchy the Jumpin' Bean is. Iwant to get another one and mount my TeeDee .049 or the Brodak MK II .049 and have some more fun.
