Don’t you want a handy slope model that's also "Flitschenfest"? Or a model with a mercilessly solid wooden construction, which you can also fly on the front or the backside of a slope? Then let the new Birdy DS convince you!

The most important changes from the Birdy-DS at a glance:
Wing profile (HN 871)
Cross-tail without underslung fin
Smaller ailerons to avoid flutter
Stiff control runs with cross-strengthening,
Very sturdy fuselage with continuous plywood reinforcement
Of course a Flitschenhaken!

If you want to leave your valuable crunchies (molded models) on the ground when flying new slopes, or want to fly at a new location without cares or worries then you will make the right choice with a Birdy-DS.

Birdy DS

Having completed the kit and taken it out on its test glide I'm really surprised at how well this little glider goes. I test flew it in 12mph winds which wasn't ideal but it's really manageable, has a surprisingly shallow glide angle and despite the dihedral was pretty much unaffected with side winds. I'm completely sold on it now and I'm looking forward to getting it onto the slopes! The build log's really useful but watch the siting of the elevator horn, I had to re-locate mine further outside of the "wedge" allowed for the rudder movement. I may even try a Spinnin' Birdy next!

I'm still building this kit so I'm some way from flying it but it's a cleverly constructed little glider and looks like it's going to be incredibly strong. I'll update with the maiden fright when I get there!

Birdy DS slope soaring in Stroud

Very pleased with my Birdy DS. The accuracy of the cut parts is superb. But this not a plane for the novice. For instance the push rods need to be cut and bent to length but they have no adjustment. You need to know how to manage this sort of tricky issue.
Once built the plane is a delight - floats and thermals with the best but also has a huge turn of speed. Robust construction. I lost power and the plane spiralled to the base of the hill. It had no right to survive that!

Excellent laser cutting. Clever design.

An interesting wee model to put together. Some considerable thought has gone into the design and construction. Well executed.

Service / customer service excellent delivery fast would recommend Hyperflight.
I'm very new to RC anything & from what I've learnt so far I can tell I've hardly touched the surface so I think my comments are probably best kept brief in relation to the build so far.
On receipt I would advise putting selotape on the strips of leading edge shapers & 4 rows of webbing as they need to kept in order, are very delicate & easily come loose.
The instructions could be updated, not least because of a comment relating to Andreas Decker who is no longer with us.
Within is included a web link to a German rc forum, I used this also for the colour photo's & found it a great help.
The central rib of the jig onto which the convex wings are built is too delicate, but this shouldn't put you off I managed it.
Take good note of the advisory comments.
The plywood that has hexagonal wholes to hold the wing nuts during build, failed & soon wore into circles, I would advise gluing nuts in (without affecting threads, obviously).
