The new MastR sail is a direct development of the Z8 sail, created by adding a central hole for
the kingpost and reducing the number of battens in order to improve glider manoeuvrability.

In terms of performance, manoeuvrability and simplicity of flying, the new MastR is an excellent
kingpost hang-glider.

Here some important changes that have been made on the Z8 sail with respect to the old Zero-7
model.

These changes have also been incorporated into the MastR: the leading edge is not interrupted
on the nose by the mylar pockets. This allows perfect, uniform tension distribution. The new sail
plan design has eliminated all small imperfections, at all VG positions. The double surface sail has
been re-designed for perfect tension distribution. New reinforcement design has enabled a re-
duction in weight. The size Large has one extra batten with respect to the size Medium in order to
reduce deformation of the wing profile at high speeds.
The lower batten pockets have been re-designed to simplify the insertion of battens and to prevent
them from emerging from the batten sleeve, when the hang-glider remains open for an extended
period at the launch site with a strong wind from behind.
We decided to use a single pitch cable to obtain a better ratio between performance and handling.

The standard version is supplied with a dacron sail, called “Square”.
The frame has profiled down-tubes with rubber on trailing edge, type aerosafe + round speedbar.

This hang-glider is recommended for experienced pilots who do not want to fly a kingpostless glider.
The MastR is ideal for all pilots who wish to fly cross-country, with the intention of increasing their
experience, but without sacrificing simplicity of flying and landing.
