AS 25 2600 (oz13040)
About this Plan
AS-25 2600. Radio control sailplane model. Wingspan 2600 mm.
The original 1942 designed AS 25 (oz13031) was a 74 inch free flight model. This here is modern redrawn version, enlarged for RC.
Direct submission to Outerzone.
Quote: "Hi, As promised, here are the plans for the 2.6 m (102 in) wingspan AS-25 RC. RC 4-way, ailerons, elevator, drift and tow hook. There are some photos, plans in PDF and DXF format. Cordially, Laurent"
Update 19/05/2021: Replaced the CAD zipfile with a revised version, thanks to Laurent.
This plan is available for download in CAD format.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsLaurent. Super thanks for sharing so my enlarged AS14 CAD Design is not alone here ;-). You build a beautifull plane also one of my favorites. Cheers,

I concur. Looking at the drawings I see sensible and meticulous design, surely a large number of hours to design the immense variety of components. Looking at the photos what I see is the painstaking assembly of those complex and individually fragile components into a very elegant ensemble. Each engineered part was machined into a sculpture; of course there is much to thank CNC for all this, but the thought behind the machine is what really counts :-)
The only negative thing I can say is that the designer decided to forget the original outboard leading edge slats which would be another challenge. This is a chicken-like thing to do, but really I don't know if they would be of any benefit :-))

Thank you Matitzo and Miguel for your feedback. The parts were not cut at the CNC, but indeed by hand. For the RC version, I did not make the leading edge slats because I think they are useless.
Matitzo, your AS14 is really great too.
Laurent - 19/05/2021
No CNC, all by hand? I appreciate your skills already, now this piece of information propels my admiration even higher! May your blades never become blunt :-)

Do you have any CAD files for the movable rudder?

Just a quick question , a lot of the former's are specified as CTP is that light ply or regular Birch plywood?
Henry - 12/06/2021
Henry, CTP is closer to Baltic Birch. I have some 1/8", 1/4" and 1/2" Baltic and the outer layers are wood with the inner some sort of wood product, possibly sawdust and glue. The stuff is heavy, the 1/2" is seven layers with two of the inner ones seemingly wood, and the 1/8" and 1/4" are three layers.

CTP is simply the abbreviation for the french "contreplaqué" meaning plywood. It does not say what plywood...

Any info on how the fuselage was stained? I'd like to duplicate that.

Lewis, I have made a 'tea' from a teabag in the thinner then mixed that into the dope. Should work with anything similar to get the older antique look. Also have a can of 10 year old nitrate dope that has oxidized to a light tan color so I get the same effect regardless.
See (oz1429) photos 03 and 04 for my Roaring 20s done this way.

Thanks Bill. A good idea. I was thinking of shaping a foam plug for each panel section then covered with a thin veneer. I also thought of printing wood grain to tissue and applying to the plug. Your idea is a lot easier.

* 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.
