Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

    ScaleType: This (oz1857) 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.

    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Westland_Lysander
    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.

I have just built the Lysander and I was having trouble tensioning the motor. On the plan file it says 16 strands of 24” of 1/4” which = 32’ rubber in total. The original plan with the supplement says 8 strands of 36” of 1/4”which = 24’ total. I just thought you’d like to know. Kind Regards, P.S. any tips on tensioning the motor to fit the model would be appreciated.

For rubber models with large motor length and number of strands the motor is usually braided. the propeller assembly will have a stop that captures the prop shaft preventing it from turning while retaining enough winds on the motor to keep some tension on it and prevent bunching or sagging while still allowing the prop to freewheel.

* 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.


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.
