Api/Bee

Apis/Bee is a single-seat middle-wing ultralight self-launching glider with T-shaped tail. Featuring the same wing- and tail section aerodynamics as the Sinus and Taurus, you can be positive in Apis-Bee stellar gliding performance. In fact, Apis-Bee holds several World Records!

Construction

ll plastic parts are made in AFK, GFK and CFK technology while all main parts are LN certified. The plane itself is made of armored plastic in combination of epoxy resin enforced with honeycomb, glass, carbon and kevlar fibers.
Wings are made in sandwich construction. Top and lower surfaces are made first then all additional elements (main spare, basic ribs, air-brake enclosure, ….) are glued into top half. Air-brakes expand from top half of the wing only. Rudder is built the same way from two halves wit built-in control connections and hinges.
Fuselage is built in combined AFK and CFK manner as a combination of shell and sandwich construction. Two halves are are built so that most of the elements are glued into one of them and then both are put together. Carbon and kevlar are used from nose to wing section, while the rest is made in sandwich construction. Cockpit is covered with single piece Plexyglass cover opening in forward direction. Pitot tube and air vent (for airing cockpit) are built into nose. Static pressure is measured on the side of the fuselage. Radio antenna is built in to aft vertical stabilizer. Tow tie is mounted on the lower front part of the fuselage. Rudder pedals are adjustable.

Tail section: Horizontal stabilizer and rudder is made the same way as wings: in sandwich construction.

Controls

The Apis/Bee handles with ease and elegance like all the Pipistrel aircraft! Vertical rudders, air-brakes and ailerons use rigid connections (tubes and bearings) while vertical rudder is connected with steel cable.
All controls hook up automaticaly, so you will have no problem assembling and disasembling the aircraft for the storage in a trailer.
Landing gear is a non-retractable wheel with disk brake under the cockpit and a small one on the tail. The wheel brake is accessible by air-brake handle.

Frequently Asked Questions

What is new with the new generation Apis/Bee?

The current model of the Apis/Bee by Pipistrel is the second generation of Apis. This section will provide an insight of the major improvements over the previous version.

1 Retractable gear, steerable tailwheel
Immediately noticable from the outsite, the tailwheel is recessed and steerable through the rudder pedals. This makes taxiing like a dream! Further, the main landing gear is retractable (optional equipment) by manual mechanical installation. The force on the handle is super-low, even lower than on the Taurus and the reliability is much better than electrically retractable landing gear with other designs. Both these improvements of course improve gliding and climb performance!

2 Ballistic rescue system
The Apis/Bee can now be equipped with a ballistic total rescue system (option)). It is no longer necessary to wear a backpack parachute, which is great benefit for the larger pilots. With the ballistic rescue system, the safety is always with you. The activation handle is a pull type and located at the right hand side of the main instrument column.

3 Much larger cockpit
The new seat shape and back allow much more room now. Further, thanks to the ballistic rescue system option and different system of cushions, there cockpit room has been improved by a considerable margin. Of course, the pedals remain adjustable in-flight as standard. The headrest is now standard, it is an addition with a simmilar fully adjustable design from the Taurus.

4 Lighter engine, redesigned performance propeller
The engine selected for the Apis/Bee – the Hirth F33BS is renowned for reliability and excellent power-to-weight ratio. We have designed an all new propeller and the result is a 15% performance in both take-off and climb segments. Apis/Bee now climbs in excess of 3 m/s (600 fpm), which is more than most self-launching gliders and more than a glider tow.

5 Less vibration, better cooling
Now used are double shock absorbers sets on the engine attachment points to reduce the overall vibration. The engine cylinder head is a different, new model which improves the cooling.

6 Larger 20 litre fuel tank now standard in the wing
For safety and convenience reasons, the fuel tank has been moved from the fuselage into the wing. This allows for a much bigger fuel tank (20 litres instead of 8 litres) and of course much more autonomy and freedom of flight. Having all the fuel in the wing is a great safety improvement as well! When assembling the Apis/Bee, you connect the fuel using the fast-click-on connector, and you are ready to go.

7 New instrument column
The instrument column is now lower and wider at the top row, while providing more legroom. Now, the instrument panel can also fit the modern gliding computers, such as the color-screen LX8000! Because of the lower profile of the instrument panel, forward visibility is improved during take-off and landing.

8 New ergonomics of cockpit controls
The cockpit handles and their positioning has been updated for better ergonomics for both small and large pilots. The handles resemble the positioning in the Taurus, for easier type training.

9 Engine management system from Taurus
Our praised (Klaus Ohlmann says it is the best!) engine management system Ibis II from the Taurus is now standard in the Apis/Bee too. The pilot must only select the position of the engine (up/down) and the system will take care of the rest. Also, you can use the Taurus to train Apis/Bee pilots for a reduced learning curve and no problems with transitioning to the single seater.

10 Rebalanced and lighter control feel
Primary flight controls (ailerons, elevator and rudder) have been harmonised to give the best possible pilot-feel even at all speeds. The ailerons is no longer hard and the Apis/Bee now handles as lightly as the Taurus. The Rudder pedals and wire ropes have been redesigned for smoother travel as well. All control sufraces now feature different high performance leak-free gaskets, which also contribute to a more direct and lighter control feel, while at the same time improving the overall performance.

11 Optional 5.00×5 wheel
As an option, it is possible to have the bigger 5.00 x 5 wheel/tyre. Standard is the 4.00 x 6. The bigger 5.00 x 5 wheel can be installed both as fixed and retractable! Very suitable for grass and rugged terrain.

12 Leather interior
People often ask – is the leather upholstery offered as optional equipment truly leather? Yes, we use 100% genuine NAPA leather with Bovine texture in choice of colors which are published on our website (see Gallery). The customer can choose the color of the seats and surrounding upholstery in a single color.

13 Solar Panels
Solar panels can be installed as an option, they cover for all electrical consuption during gliding. They will recharge the battery on ground as well.

14 An engine unit which can be removed in minutes
The complete engine unit is now modular, including all of the connections (fuel, electricity, sensors, etc.) which are now done with connectors. For maintenence, you can not dismount the whole engine unit in minutes!

15 Much faster engine extension/retraction
The engine extension/retraction (engine up/down movement) now only takes 6 seconds. This is much quicker than before and improves both performance and safety.

16 Better cockpit ventilation and plexy defogging
Now more fresh air will be entering the cockpit then ever before. It is also strategically distributed over the canopy to prevent fogging when flying below the cloudbase.

17 Safety Firewall
A major addition is also the safety firewall between the cockpit and the engine compartment. It improves safety and cancels a lot of the engine noise which would otherwise be entering the cockpit.

and 116 other little improvements!
Which contribute to a lighter, safer structure, easier operation and better performance.
