About this Plan
Algebra 2M. Two meter class soarer for 2 function RC.
Quote: "Having placed a 2 metre wing span restriction on a soaring design, a low aspect ratio layout is dicated in order to keep the wing loading within practical limits. A mean wing chord of 22cm (8.7in) was selected giving an aspect ratio of 9:1, also keeping the wing loading down to 26 g/dm2 (8.6 oz/ft) for a sturdy structure capable of withstanding the rigours of multi-task flying.
A thin 8% wing section based on Eppler 176 is used, in an endeavour to give an above average flying speed, and flat glide without the necessity of carrying large amounts of ballast. The fuselage is kept as small and as clean as possible, to minimise drag at the higher flying speeds. The structure is heavy because of many bad habits cultivated by building too many F3B models, but is nevertheless very strong. Construction is quick and simple, because I am impatient and prefer flying to building!
We all have our own particular construction techniques which are satisfactory on an individual basis. Many different construction styles can be used to assemble a particular structure, and they can all be considered successful, if the completed structure is as strong and true as the designer intended. The following instructions should therefore be considered perhaps as guidance notes...."

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.
