MENTOR 7 Light – Hybrid 2.5-liner
The MENTOR 7 Light is characterised by its completely new design as a "hybrid 2.5-liner" and carries the genes of the XENON. Thanks to the drastically increased performance, its cross-country potential sets new standards in the EN B class. With its intelligent lightweight design, we are meeting the great demand for light, durable XC gliders.
The best possible combination
This performance optimised 2.5-liner flies more comfortably than many 3-liners. How come? Philipp Medicus, Head of R&D at NOVA explains: “The difference in design between the MENTOR 6 and 7 is greater than between the 2 and the 6. Absolutely everything is new. Only the pilot group and its potential as an XC machine are the same.” This means the MENTOR 7 Light will appeal to all cross-country pilots who would like to achieve their distances within the B class and who want a state-of-the-art “teacher” at their side.
Intelligent lightweight construction
Among other things, the MENTOR 7 Light owes its outstanding performance to the 66 cells and its complex inner construction. In order to live up to the name "Light", the wing features high-quality, durable lightweight materials. Ideal for ambitious cross-country flights and every conceivable hike & fly adventure.
Optimised XC potential
The strength of the MENTOR 7 Light lies in its “actually usable performance”. Fully accelerated, it cuts solidly through unstable air masses, and the C-steering can be used to efficiently mitigate turbulence. Performance, smooth flying and safety are the hallmarks of a genuine MENTOR. The MENTOR 7 Light also impresses with its manageable extreme flight behaviour. For example, accelerated collapses are even more gentle than on the previous model. All NOVA test pilots confirm that this wing, with its moderate aspect ratio of 5.5, is very pleasant to fly and additionally has even more top speed than the MENTOR 6. The ideal prerequisites for breaking personal records.
Perfect pitch (control). The MENTOR 7 Light has Height Adjustable C-Handles (known as HAC handles) on the risers, that allow pitch control in accelerated flight, which was previously limited to two-liners such as the XENON. This means it is easy to compensate for turbulence and flying XC is far more efficient. Those with no previous experience of C-steering can take a relaxed approach to learning this new flight technology with the MENTOR 7 Light and gain a real performance advantage for themselves. Please note: how this C-steering works is explained below.
Like our XENON, its "little brother", the MENTOR 7 Light does not work without rods. Therefore, we say goodbye to our "Easy Packing" principle in favour of a clear performance advantage. This basically just means that we recommend you don't stuff the MENTOR 7 Light into the pack sack crumpled up, but rather folded up and packed with the help of the enclosed pack roll. A little effort is worth it, as this means the rods remain in shape, the lines are tidier and it saves time during the preparation before the next flight. Please note: when buying the MENTOR 7 Light, you can decide between the Concertina Bag Light or a rucksack.
The most prominent feature on the MENTOR 7 Light’s new Speedbrake Riser 2.0 are the HAC-Handles. Another striking feature is the "Baby-B" line, which acts as a moveable pulley on the B3 line. This means the riser is a little more complex, but it is still clearly laid out and easy to handle even when launching. Good to know when ground handling: you can kill the MENTOR 7 Light very effectively using the C-lines. As there is no C3 line, what does not work so well are asymmetric corrections via the C-lines. For lateral directional corrections we therefore recommend using the brake.
Pilot target group
The MENTOR 7 Light (EN/LTF B) is a state-of-the-art "teacher" in the tradition of the MENTOR series (performance, smooth in flight, safety), which does not tend to overshoot during inflation and impresses with an extreme flight behaviour that is manageable for its class. As a hybrid 2.5-liner, it is suitable for cross-country pilots who are experienced in handling EN B gliders, or who want to get the maximum out of a flight using the speed-bar and HAC handles. So if you want to familiarise yourself with pitch control similar to the flying feeling of a two-liner, this is the wing to fly. It is important to understand that the hybrid construction partly influences ground handling and means, for example, that the use of the B3 stall is more effective than classic big ears.
Hybrid design as a 2.5-liner
On the outer wing the MENTOR 7 Light is a two-liner, in the center a three-liner. This means this “2.5-liner” does not have a C3 line. The smart redistribution of the attachment points and a profile optimised for accelerated flying make the MENTOR 7 Light a comfortable and potentially record-breaking fast cross-country glider. At the same time, the safety and smoothness in flight remains typical of the MENTOR and accordingly the certification also resulted in EN B certification.
Speedbrake Riser 2.0 incl. HAC Handles
The MENTOR 7 Light has HAC handles (Height Adjustable C-Handles) on the newly revised riser. With these, pitch movements in accelerated flight can be compensated for in the best possible way. This means that on cross-country flights you to get from A to B even more efficiently - i.e. faster and with less sink. In addition, the C-steering is very comfortable and requires little effort.
Aerodynamics optimised for speed
The design of the MENTOR 7 Light focused on speed. The profile ensures a high degree of pitch stability even at low angles of attack. In numerous simulations, the ballooning as well as the stress distribution was refined to minimise the deformation of the glider when accelerated. The cell openings are designed so that the internal pressure remains ideal even in accelerated flight. The result is excellent glide performance with an exceptional level of stability.
