About this Plan

Wittman V Racer. Peanut scale rubber model racer.

Direct submission to Outerzone.

Note this here is the plan as printed in Aeromodeller, July 1983. The same design appeared in MB, July 1974.

Quote: "Peanut Wittman VW Racer, by Walt Mooney.

Racing pilot/designer/builder Steve Wittman must have had modelers in mind whenever he dreamed up one of his famous racers. The lines are always clean, simple, and easy to reproduce.

To anyone who has even the slightest interest in aviation, Steve Wittman needs no introduction. This racing pilot from Oshkosh, Wisconsin, has been building winning racers for more than forty years, and is still piloting them in races wherever a race is promoted. His designs are famous for being light, simple, and fast. They are also famous because they have not followed the 'French curve' smoothness approach to aerodynamic efficiency. Thus, his airplanes have not always looked fast, but they have always been fast.

This VW powered racer is in the best tradition. It is a boxy, angular airplane. Nevertheless, looked at carefully it is streamlined in all the right places, has been simply built, and is obviously light in weight. One design approach Steve has used for years is the wire-braced wing. By using wire bracing, the wing can be made much lighter and thinner. Keeping a racer as light as possible is important, because a considerable portion of the drag of any airplane is induced by the amount of lift developed to hold the airplane up and the lower the weight the more quickly the airplane will accelerate, both on the initial takeoff, and after each pylon turn.

There are two intentional deviations from scale in the model; the area of the horizontal tail has been increased slightly, and the dihedral has been increased from nothing to an eighth of an inch. The wing has been designed to use wire bracing just like the real thing. Note that the top longerons are spread wider apart than the bottom longerons..."

ScaleType:
  • Wittman_V-Witt | help
    see Wikipedia | search Outerzone


    ScaleType: This (oz13425) 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/Wittman_V-Witt
    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.

User comments

I built the V-Witt racer oz13425 [main pic, 006] and pics were included in the June 2020 issue of Aeromodeller with the re-published plan.

Built mine along with PB Guy in a group build. Enjoyable build ... still have to fly it!

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.
