About this Plan

Orcrist - Control line combat model for 2.5cc engines.

Quote: "Top notch combat design. Winner of the 1971 British Nationals... ORCRIST was not really designed - it just sort of happened in late 1969! I was greatly impressed by the handling qualities of the Ruteress (oz2602) design but was less enthusiastic about its strength; accordingly I merely grafted a tailplane onto a normal Liquidator (oz9761) type wing and produced the prototype Orcrist. This model is still in existence and was used to win the finals at Cranfield and the Nationals. Since this time various wing sections, ranging from 7/8in flat to 1-1/4in 'full stunt' have been tried but the original has not been improved in any way! But why the name Orcrist (pronounced as orc-rist with short 'o' and 'i')? Readers of The Hobbit by JRR Tolkein will recognise this as the name of the Elven sword used by Thorin Oakenshield, the dwarf, in an important contest (the battle of the Five Armies) to overcome his enemies - the Warlords! Rather appropriate don't you think? Actually, although Orcrist had some magical properties, it was never claimed to fly - and its final fate was to be buried under the soil, so do not get too carried away with your fantasies!
As for construction, care must be exercised in selecting wood in order to produce a light, strong model. The grades indicated on the plan will produce a model weight of 15-16 oz. which I consider to be the best compromise. If you really want the performance you can use lighter grades but don't blame me if it falls apart! The construction is conventional combat practice and will be familiar to many. PVA glue should be used for leading and trailing edge laminations, and epoxy for the engine pod..."

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

* 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.
