One of my favourites. A high aspect ratio wing using the HS522 wing section, thickened slightly. A lovely model in light conditions, cranks over and climbs beautifully in a thermal.
The downside is I didn't bother putting a spar in the wing, so as soon as the wing gets some speed on it does an impressive flutter.
I also tried to install flaps on this wing, but made them too long inboard so it's nigh on impossible to compensate for the pitch up on deployment. In the end I just coupled them with the elevons for roll only.
Next version will feature a meaty spar, re sized flaps and scope for ballast, all in an attempt to make the wing more versatile.
