OUTERZONE - Model Engine Plans

edholly · Apr 13, 2022

Steve at OUTERZONE has now created a category and loaded an initial batch of 36 plans. If you have any that aren’t on the site or have some that are your own that you have made an engine from, then Steve would be happy to load them. They need not be on CAD, so long as they are legible and correct with an engine made from them. If they are your own, then it would help if you could compose a story about the engine, and maybe a link to a build thread. Of course, a few photos of the finished engine would enhance the listing. If the engine plans are not yours, then please identify the designer and approximate era the design was made.

I would like to thank Steve and Outerzone for creating a new section for our passion and having the engine plans in an easy to access inventory.

Also, as I wrote previously, as a kid I used to often spend my pocket-money to buy MAP plans at the Sydney Hobby Shop named HOBBYCO – and here we are as adults having them available to us free of charge. There is a donate button at the bottom of the main page of OUTERZONE – so if you do avail yourself of a plan or two, please consider contributing – we are very lucky to have this site.

Additionally - if you do download and build an engine from the Outerzone site - why not mention it here - keep this thread going and we can see what plans are the most popular.

I’ve added a Humbug, Vega 30, and maybe a Little Dragon to my “Need to Build” list.
Thanks for your efforts!
