X-RES 2m

The X-RES is a built-up CNC cut balsa and ply kit designed for the new F3-RES high-start launched 2m Rudder-Elevator-Spoiler glider class popular in Germany and Austria.

The X-RES is the latest development of Alois Janowetz, the designer of the Minores, one of the top models of the 2015 season, with the many competition wins (including 3 victories in the Bavarian Open) in Austria and Germany. The new X-RES performs even better, with a documented sink rate of just 0.31 m/s (61 ft/min), which is exceptional for a 2m model.

The X-RES has pleasant flight characteristics and brilliant performance. The model is very agile and extremely easy to fly. The pre-production models enthused the test pilots and the flight performance was clear from the start. The sophisticated design and the brilliant use of weight-optimized materials allows a flying weight of 420g and thus a wing loading as low as 11 g/dm2 (3.7 oz/sq ft) out of the box, giving amazing performance.

The large 2-part spoilers allow almost vertical descents without an increase in speed. The wing separates into three panels and the tailplane is removable making the model very easy to transport.

The CNC cut kit has very simple and robust construction. With the exception of the 6 mm CFRP rods for the wing and the GRP rocker for the moving tailplane only selected and optimized balsa and plywood are used.

All components are bonded with easily available glue and the model’s construction is simple, considering the excellent performance potential. The fuselage is already prepared for a ballast tube, which can take weights up to 250g. The design allows the use of commercially available and easily obtainable components. The recommended battery is an Eneloop E-550 or 800mAh in cube form. Oralight covering is recommended. An adjustable tow hook is standard and is included in the kit.

The kit includes a colour plan. See below for a link to an English translation of the X-RES build manual. For more info about the X-RES see this and this RCGroups build threads.
