I bounce around way too much, still need to cover the Veco Brave, but recently I have been tasked with the job of creating an exact copy of the the Carl Goldberg 42” Shoestring Stunter. I know there is already a newer Shoestring type kit available, but I like original. Much like i did on the Veco Brave, I tried to stick with the creators originality. I hope to wind this project up next week with pictures for the forum. Then I can hop back onto the Brave and get it ready for flight in the spring.

cheers Y’all

Cut the Number 1 rib last night… was almost a perfect match




The original is in the cutout of the duplicate. Just need to narrow the tab behind the spar on the duplicate and we’re there.

next to tackle the rest of the ribs…

Original CG Shoestring Stunter Kit Resurrection Project Update: I have finished drawing all the original parts of the kit in CAD. Looks like I’ll be using two 3/16” and one 1/8” laminated SIG Balsa (have on hand) to get the 1/2” thick fuselage nice and straight. Should be strong enough with the glue. The original fuselage weighed in at 3.8 oz… this is 2.2 w/o glue.. might even slip 1/8” ply in middle vs balsa but will look at that after its glued up. The important thing for me is keeping with originality as much as possible.

I have completed this project. Exact replica of the parts (or as close as one can get with the CAD and things actually measuring and fitting together). The only changes i have made to the original kit parts are 1. Used 3/32 balsa for ribs vs. 5/64, 2. Used 1/8” ply for wing reinforcement vs. 3/32”, 3. Used 1/16 sheeting for top and bottom of center wings, 4. Made sure the wing tip parts actually mate together (original parts had gaps in the joints). Other than that, everyone else matched up fairly accurately.

I know others have created a newer version of this great Stunter… I wanted to do something different, and that was create a replica of the original.

I will be making short kits after Easter. PM me if you are interested. I have also re-scaled up the plans so the printed 48” x 36” plan has a wingspan of actually 42”.

I also will offer laser cut cardboard templates for you real scratch builders.

The Shoestring is the best non-flapped stunter that I have flown, I like it better than the Flite Streak. I would be interested in a short kit.

What engine are you going to use? I find that most of the old planes designed for the very light weight Fox 35 are a challenge to balance without gobs of tail weight when using modern engines, especially those with a muffler. I usually end up moving the wing a little bit forward if there is room and/or lengthening the tail. The Shoestring already has a shortish nose so a tail stretch might be a good idea.

Of course if you are using a Fox 35 you will be “golden” except you will then be subject to the old Fox “burp” when mounting on a profile ship. Sometimes a good .20 at about the same weight will fly the Shoestring well, but I haven’t tried it myself. I heard the old Veco/K&B .19 is a great performer as is an OS .25LA if you can find one but Fox 35s are easier to find.

Looks like you have drawn the ribs such that the building tabs are not included. The tabs help immensely to build a straight wing on a flat table without a jig. I suggest you consider adding the tabs to the ribs.

Hye Flyer:

Looks great! But don’t all of the ribs have to have the tabs?

I thought the same but since I used an unmolested original kit as my templates… and only the no. 1 and no. 8 ribs had the tabs.

I would be interested to hear how it works out. Please post your build pictures.
