Brand new Challenger Sport 2E with its beautiful X-tail and elegant, tapered leading edge wings is simply breath-taking to watch as it thermals almost out of sight at your favorite field. This plane is an incredibly well rounded, stable and predictable flyer, suitable for experienced beginners as well as advanced pilots. With its fiberglass fuselage and its fiberglass reinforced, balsa sheeted foam core wings this model can handle most moderate aerobatics. The careful use of composites with competition balsa, creates a good light structure that will hold its shape for a long time. The synergy of low weight and strong structure is very unusual in a production sailplane and can only be achieved with careful attention to design and construction. This model is considered one of the best values on the market today. Each part is carefully hand-crafted with meticulous attention to detail. Two meter Challenger is considered one of the best values on the market today.

Virtually perfect, very well made and extremely clean electric 2m sailplane.

Special Features:
- Control Surfaces: Ailerons, Elevator, Rudder and Flaps

I bought this model as my first glider. It went together quite easily and is almost complete now. My observations are: did not like the idea of glueing in the wing servos so used the mounts from esprit. Internal fuselage linkages are very tight and I would recommend moving the servo tray forward from the position shown as it is very difficult to access the linkage adjusters at the servo end. ai replaced the very flexible rudder linkage with a carbon tube and music wire - it is almost impossible to access the insode of the fuse to epoxy the flex tube in place inside. The tube and wire only needs to be glued at the exit. Wing hold downs hard to install - I replaced them with 6-32 T nuts and added a small backing plate. Drilling holes for the wing mounts is a very precise operation any mistake on the angle will result in not being able to start the bolts in the threads. Lastly I found it impossible to balance with the recommended 3S battery @ 180 grams - I needed a 5000 at 360 grams to balance level at 70mm from the leading edge. AND lastly this box for inputing a review is ridiculously small!
