Introducing the SERA DS-X produced by Japanese manufacturer Cassiopeia.
The SERA DS-X like the SERA Sailing is a very light, well constructed, full house sailplane that flies as well as it looks! No, we're not kidding! This 60" ship tracks like it's on rails. The similarities between DS-X and the Sailing are numerous so I will only go into how the DS-X is different than the Sailing. Generally speaking it is the performance. The DS-X has a noticeably higher roll rate; it reaches higher top speeds than the Sailing given it's smaller wing planform. Our experience with the plane has yielded no bad habits. It really is easy to fly. Flying Aerobatics with it is easy peasy, enjoyable, and predictable.
Here's a build thread you can check out.
OK now that I've got the flattery out of the way let's talk shop.
The DS-X is a 1.5 meter sailplane that sports a lightweight balsa built up wing and fuselage construction. The plane can be built as an electric glider or as a pure glider. The wings are fully sheeted making the DS-X a little tougher than a typical film over open rib thermal ship. The DS-X sports ailerons, flaps and a V-Tail. The flaps and ailerons are controlled by independent servos allowing full featured mixing; full span ailerons, snap flaps, crow/butterfly etc. The servo pockets are precut and the control surface hinges are pre-installed.
The entire unit feels good in the hand, not too soft or flexy and light as a feather. Something to keep in mind is to keep this plane as light as possible when fitting it out. Lighter equals better performance and better crash survivability.
In the small bits department the kit comes with control horns, carbon tubes, and rods for joining and retaining the wing. The kit also provides servo trays (pre-installed) and velcro. An assembly manual (with decal set) is included. The manual is written in Japanese but has clear pictures that will guide all but the newest builders to a successful outcome.
