About this Plan

Obelix. Radio control slope soarer for 2 channels.

Quote: "Pull-out plan for an exciting two function slope sports model ...The present design will fly inverted with very little change of trim and will perform any combinations of aerobatics involving rolls, inside and outside loops. Most maneouvers in the book are easily performed but this is a 'fun' model and I would expect it to be out-performed by a smoother larger model. Still, they cost more... I am currently using blue foam panels, the completed model being covered in lightweight tisue using wallpaper paste before the iron on film. You can however cut your panels from expanded polystyrene foam building the model as per, but cladding with obeche veneeer... a third alternative is the built-up construction as shown on the plan."

Hi Steve, Here is another Officeworks scan, the Obelix slope soarer... I have straightened and squared up some of the main construction lines, they were a bit messy and out of alignment. The fuselage 'airfoil' section measures 14 5/8" from LE to hinge line... Cheers,

Direct submission to Outerzone.

Update 31/05/2017: Added templates for optional foam wing, thanks to KraftyOne.

Hi Steve, Further info on the Obelix. I found this jpeg of the Obelix foam wing templates on one of my HDs, not sure when it was scanned in or at what resolution. I cleaned it up a bit, hope it is usable. Cheers,

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

I've built two powered versions of these. Most excellent with a huge wing area allowing flare to almost stationary for landings. Both ran with 2 ch and an Enya 09.
I built the outer wings with ribs perpendicular to the top spar, introducing a very minor dihedral.

Hi, I've just finished the updated Obelix, naturally named 'Obelex' by Chas Gardiner, as it's the electrocuted version [pics 003-006]. It flies every bit as well as the original - in fact better than I can! Huge fun, does things that would haul the wings of other 'normal' models - I love it! The flying site? Just a few miles from Leek, UK. Regards,

Does anyone know which aerofoil is used on the Obelix? I’m trying to get a friend to cut me some foam cores but he needs the aerofoil. Thanks,

I have a feeling it was a 'that looks about right,' aerofoil. The closest you might get might be the E374, with a little reflex added via the control surfaces.
Else trace the ones on the plan and make templates from them. Aerofoil accuracy is not that imoietant with the Obelix.

* 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.
