I'm thinking of getting the Brodak Goldberg shoestring . Would a OS 25 LA CL engine work in this model . Or would the evolution 36 be a better choice ?

Thanks JIM

The 25 will work fine....

Geoff Goodworth · « **Reply #2 on:** May 01, 2015, 08:22:24 PM »

LA 25 will be fine. I fly mine with FP 20s.

Between those two options the .25 is by far the better choice.

Jim!! Go 'fer da' gusto!! Mount y'erself a good 'ol Fox 35 'wit a 3 oz tank and have a ball!!

Go with the LA 25 and you will be happy you did. Get EVO 36 for a built up plane.

Thanks guys I already have the EVO. Just ordered the OS 25

NOT the Shoestring, but i have the Brodak Goldberg Buster and I got an OS 35S on the front of mine and love it.

JIM Nordin · « **Reply #9 on:** May 03, 2015, 01:04:45 PM »

What length lines are you guys useing for the shoestring with the OS 25 ??

Thanks JIM

I would start with 60 or 61 feet eyelet to eyelet. You can easily shorten them from there if need be. They haven't invented a line stretcher yet! If you haven't flown a model with an LA.25 yet, it will surprise you with what it can pull. I don't quite go as far as the claim "same as a Fox .35" because they runs so differently and make a different kind of power. I have a SIG Twister that I fly now and then with an LA.25 on it. The Shoestring is smaller, a bit lighter and I think a cleaner design, so you don't want to make the lines shorter than you have to. Before I re-engined my P-Force, I flew it with LA and FP .25's and I was at least 60 feet eyelet to eyelet. Use a APC 10-4 prop, about 10,500 take off RPM, 10 or 15% nitro fuel, and have at least a 4 ounce tank on it to do the pattern in cooler weather. That is pretty much the settings for anything I have flown with the .25 engines, including a Top Flite Flight Streak ARF, which is about the same size and weight as the Shoestring.

Hey, that's right, you are in the area here aren't you? Have you hooked up with the Lafayette Esquadrille yet? You're on the other side of the river aren't you? I just changed jobs and work days shift now after 19 years of second shift and will be getting out a lot more often and make club meetings now. Hope to meet you in person soon.

I'm right next to the Columbia bottoms wildlife area about 4 miles from the 270 and river Veiw dri. I talked to Sparky a few times

Geoff Goodworth · « **Reply #14 on:** May 03, 2015, 08:14:13 PM »

Further to Dan's comments, I have flown my Shoestrings on 60 ft lines in still weather and 58s if it's a bit windy. But then, I also use FP 20 engines—I don't know whether that makes a difference. Also, mine have each weighed a bit under 29 oz.

Heck, we're practically neighbors. I'm just up 270 from you in Florissant. We'll get together sometime soon.

One of my favorite all time models was a Brodak Buster powered by a Tower 40, tongue muffler, needled to a screech. Handled well and went fast. I don't know what an Evo 36 weighs. If heavier might be fast but sluggish at the handle.

If you had to choose between the Shoestring and the Flite Streak to learn the pattern which will it be?

Dave Hull · « **Reply #18 on:** February 24, 2021, 06:37:11 PM »

Chewstring.

I have also seen guys play around with the Flite Streak. The popular mod seemed to be to enlarge the tail to current (ridiculous?) proportions. The upside of doing that, beyond making it less like a combat plane and more like a stunt plane, is that you can stretch the nose a bit and give yourself more room for a fuel tank.

Either way, you can learn a lot of flying with one of these two.

It's been a long time since I've flown a Shoestring, but have a lot of time on my Flite Streak ARF so I'll have to give the nod to that. A Streak bult from a kit may end up a bit heavier but not a big deal. Balance point heeds to be a bit further forward on the ARF Streaks than the instruction say. Mine is getting alittlke long in the tooth and needs some freshening up and a recover job.

I have a Shoestring and fly it once or twice a year at some of the vintage events we have had here in NC. Mine has a Mc coy .35 on it and i fly it on .015 X 60 ft lines. I can fly the beginner pattern with it, but would run short on fuel for more than that. Not alot of room up there for a much larger tank ..Gene

I have both and there's really nothing to choose between the two as far as learning the patterns. Just pick the one you like. I will say they are both rather squirly and you'd be better off building a Sig Banshee or Twister. Just a side note if you ever want to go foxberg racing you can do that with the Shoestring.

A "square-wedge" tank of similar dimensions will get about an ounce more fuel. You can also cut the leading edge back about half an inch for a longer tank. Mods for a larger tank are needed for the Flite Streak, Shoestring, and Buster.

DON'T leave off the flaps or tips. They are really necessary to do a decent stunt patter with the F-Streak. The Shoestring, Buster, and Cosmic Wind all are good stunt trainers(as long as you don't hit the ground too hard! Lines can be anywhere from 60ft. on down to 54-55ft. Shorter lines give all these planes more line tension during maneuvers.

Hello
I have built a few Shoestrings but reworked them as semi scale models but my wife did build hers stock with a Fox 35 . I prefer the model reworked as a Kawasaki Hein with Magnum GP25 for power to my OS 25 and Fox 36 versions . If using steel lines 60ft works well but if flying Spectra I can go to 64ft and they feel nice and light.
