There's a useful page with notes on the Mercury design and links to more info at ColinUsher's site:

Hi Mary, I have found the pictures of the Mercury IV, see attached [more pics 004-007]. There is one pic of the Mercury in flight as it was taking off, the others are in my back garden.

Hello, I have the plan and a laser cut kit of parts for this model but was wondering if you had by any chance any building instructions for the lovely model.

We have the original magazine article, but it doesn't contain any building info. Can anyone help Jim?
Mary - 19/02/2017
I have attached a brief document by Colin Usher with a few building instructions [see supplementary 'Construction' file] found some time ago at (this link seems to be dead now). I hope Jim finds it useful.

Many thanks alcalaino :) Colin Usher's site seems to have disappeared. I have noticed that all our links to his site are broken. Does anyone know what has happened?

Pleased to say that I have downloaded the Construction notes for the Mercury, thank you again. I was wondering if to go with the plans there was a material list required to build this model otherwise I will have to get pencil and paper and a rubber to work it all out. Many thanks again for all of your help.

* 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.
