About this Plan

Shoestring. Radio control scale model pylon racer.

Quote:- "Fred Reese's super-fast quarter midget racer can bring the hardware home for you.

The Shoestring design is based on the wing concept by Don Dombrowksi of using two fiberglass arrow shafts for both structural strength and as the wing builiding jig. As you know, building a lightweight, thin, tapered wing that is straight, can be difficult. Sheeted foam is not foolproof and is much heavier than our built-up wing. Don's experience with Formula I wing design gave us the symmetrical laminar wing root section but it took 3 wings to decide on the tip airfoil. After trying some thinner sections, the 2410 was selected for its high lift and low stall speed characteristics.

The result is a wing that will not snap out of a tight turn, yet has very little drag for top speed potential. Landings are not difficult as the plane can be slowed down without fear of stalling. Another advantage of this wing design is non-sensitive aileron control, especially around neutral. This means smoother flying and fewer course corrections and the resultant loss of speed.

The long nose and tail moments allow plenty of room for the fuel tank and the battery pack and result in less sensitive elevator control when combined wiith the forward CG location. In fact, the airplane takes a little time to get used to at first because it is less sensitive than most pattern ships, yet it flies much faster.

Construction goes very quicly once the basic parts are cut out, but some time and care must be taken to get the wing ribs and the shaft holes accurately aligned.

Begin by making 1/16 in plywood root and tip rib templates with the 1/4 in holes for the arrow shafts..."

    ScaleType: This (oz7122) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Condor_Shoestring
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
