SBXC Assembly Manual

The venerable SBXC and Super-XC are popular gliders for cross-country soaring.

This downloadable PDF document describes the step-by-step assembly with many photos and detailed descriptions.

Minimizing Slop in Control Surfaces

The popular cross-country gliders SBXC and MXC are molded performance planes. Slop is a problem, especially in high-performance gliders.
At best, slop makes flying more difficult; and at worst, it can lead to flutter which in turn may cause air frame failure.

SBXC and MXC Sailplanes

The SBXC and MXC are commercially available all-molded gliders designed specifically for cross-country competition. Their design yields high performance while also providing the stability needed to pilot them from a moving car.

Testing RNR’s SBXC Performance

John Ellias and Dan Edwards have tested actual flight performance of the popular SBXC cross-country glider. John used an on-board GPS unit to arrive at a sink polar for the glider. Dan expanded on John's data using an auto pilot.
