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.

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).
