Re: Scientific "Zipper" Build...The Zipper Gets Some Thursday Attention
A good number of Walt's Scientific plans and photos show an OK Cub, either the Model "A" or "B" drawn installed or in a photo in the plans or box. I think there may be one or more showing the Wen Mac plumbed for the separate tank. That was the nice thing about Walt's designs, he made sure they could accommodate just about any engine in that power class. Even an A.C. Gilbert .074 Thunderhead would work with the appropriate modifications and be period correct.ticomareado wrote:The general layout of this model is just begging for a reconfiguration to a Beechcraft Bonanza. With a good specimen of a Wen Mac MK II or Mk III for power.
Thanks Kim for providing a photo of the plan. I have found that by simply reprinting the pdf or jpeg using a tiling program to 4 times will enlarge the true 1/4 scale top view to proper size. I never built the Zipper, but always liked the looks of it when browsing hobby stores and Scientific ads in the 1960's and 1970's.
I was sad to hear of Walt's passing, but time has allowed many to pass on that I grew up with their plans, kits and magazine articles.

Re: Scientific "Zipper" Build...The Zipper Gets Some Thursday Attention
While Walt did keep the average modeller in mind in terms of providing kits for engines that most had, truth be told the OK flew the planes better.Having the tank on the cg was key and building them light. Putting a Cox engine on them was too heavy and placed the engine out too far. That being said, I saw a Fox .049 in a Golden Hawk fly extremely well.

I thought it looked like a tiny Taurus RC Pattern ship. As a little kid the Scientific ads were ones I could stare at for a long time!
