Title: Brodak Remake of the Goldberg Shoestring
Post by: Bill Little on December 20, 2011, 10:22:18 AM: Hi All,

A very simple request that many will know the answer for! I also put this in the Classic section, but more will see it here

I have a Brodak Profile Shoestring (Goldberg remake) and I want to recreate my original one. This means I need to know the mixing formula for the "Chartreuse" found on the old Goldberg plans. Brother Marvin Denny told me but I forgot and lost the paper I wrote it on.

I *think* it is 8 parts Cub Yellow and 1 part Cessna Green. Verify, or correct it, please!

THANKS!

I have an original ( well second issue I guess?) Shoestring at home, if no one answers before then I can look at the plans and see what I find for you,
email me though or I might forget?

Thanks a ton, Mark. Believe it or not, I do have the #16 decal that was on the wing of my original! Just a tiny bit of the original Chartreuse shows.

Thanks, Wynn, but I don't think I will need the Goldberg plans.

I built one of these back in 1968 with a Fox 25 & 9x5 Rev-Up, it was a good flyer on 52' .012 lines. Yours will probably fly great. :)

Thanks, Dan! Mine was first built in 1964 and actually was powered the first time with a Red Head McCoy .19. ;D

What a blast that was for those three summers!
