| tandem · the tandem for the most demanding professional |
The Ru-Bi 3 is the logical evolution of our biplace saga with undeniable success throughout the world and desired by professionals who want to get the most out of their flights with passengers. A new profile optimized for all flight situations allows for an even easier launch in zero wind conditions while being easy to control in gusty inflations or crosswinds. Much lighter than the previous versions and with evolved risers with more trim travel, it is certified in sizes 39 and 41 ENB. The new fabric not only manages to have a lighter wing, which helps inflation, but also guarantees better porosity on the long run. The chosen profile is much more stable and makes it easier to enter the thermal while being able to bite and centre it in an easy and intuitive way. This profile is slightly thinner than previous models and helps to have a wider speed range. The risers are nicely finished with markings for take-off position or slow thermal flight, at the same time, the higher marks allow you to choose a higher speed and a better glide ratio for long transitions in cross-country flights. The shark nose on the leading edge helps to position the wing on take-off and it makes it easier, making it unnecessary to pre-inflate to place the glider in position. The Ru-Bi 3 tandem is, without a doubt, the best option for professional and recreational use that has the latest technology and materials, being a great increase in comfort, durability and ease of use, especially in difficult take-offs. |

> EN-B approval in both sizes. > D20 and D 30 fabric with proven durability. > A very light and durable construction with optimized diagonal and secondary ribs to maintain perfect shape specially throughout the high speed range. > Tense and clean top surface with 3D on the leading edge to achieve the best internal pressure. > Crossed nylon rods forming a shark nose in the leading edge to improve inflation and guarantee extra pressure when flying at maximum speed. > Smooth and precise brake setup which, with the help of the slow trim position, prevents pilot fatigue even when centering broken and marginal thermals. |

| This glider comes in Two Standard Colours: |
| red | blue |

Custom Colours It is possible to have your Windtech glider made in custom colours but keeping the original design (pattern) of the wing. The colours are limited to those available for the glider material. |
 |
Logo Service We provide a full service to have logos put on your new Windtech glider (eg. company or sponsor logos, artwork, etc). The cost for this would depend on the size and complexity of the logo. |
 |
Fly-man glider transfer Add some unique style to your new Windtech glider with this great looking 4m wide transfer of the Flyman, Windtech’s flying mascot. You can tell us where you want it, or put it on yourself. |
| All orders with non-standard options or flyman transfer have an extra cost and a longer delivery time, depending on how long it takes to get in materials and production. If you are interested in any of these opciones please consult your dealer about your requirements. |
|
| We recommend that your first flight on your new glider be on a gentle slope in calm conditions before making any further higher flights, just to check the glider completely and for you to get used to flying it. You should use the same class of harness, and restrict the width of the chest strap, according to the glider’s certification as advised by the certification body. |
