Thomas Fischer /GER uses ORCA at European Championship F3J( 1st place team, Place 9 individual ! )

Our new F3J-model ORCA was competing successfully at the international Nuthe-Cup in Ludwigsfelde near Berlin ( CONTEST F3J EUROTOUR )...

...preliminary rounds: Stefan Eder in second place and Andreas Kunz in 4th position...Final result after Fly-Offs: A.Kunz 4th, S.Eder 9th !

The legendary predecessors of the Orca in the late 90th were the ESCAPE ( construction: Stefan Eder - airfoil: Max Steidle ) by Jaro Müller, distributed by Euromodell and the private project PACEMAKER 3 ( 4m-F3J-model ).

From the experience with these designs several projects were born ( over the years ) which constantly got tweaked and customized for special demands by the development in F3J-sports.

To best suit all weather conditions in contests and alldays flying the new model was equipped with 2-piece wings similar to the F3B-model CROSSFIRE and exchangeable tips !

This makes it possible to adjust the model to different demands with just little techn. and financial effort !
To minimize flight weight the model was designed with a V-tail and the measurements were optimized accordingly.

Further versions with special electro-fuselage and one with X-tail will follow in medium-term.

The chosen airfoil with average 8,5% thickness and 2,3% camber is optimized for custumization of proper wing depth and distinguishes itself by a particularly low coefficient of moment, good nature and good gliding performance.
In additon just small flap movements are necessary for speed, thermal lift etc.
The ORCA airfoil is based on the section of the brand new F3B-design TOOL F3B-Modell TOOL .
The new flying experience will be started when launching our new ORCA F3J-glider : Perfect launching performance and a kicking zoom thanks to optimized airfoils , high aspect ratio and f3b-like carbon spar !

Thermalling is great and you will be surprise about the good rudder response ! With 3,39m you have some kind of big f3b-model with very good glide angle ( also with low wing loading ) and very forgiving flight characteristics. With 3,63m span you will compete with those special F3J-Floater but you still have the advantage of superior glide angle. Coming down from great altitude is no problem and can be made in F3B-style as well ( full carbon technology ).

Due to large flaps and special design fuselage shape you will love to come to another landing !


The construction of the fuselage is full carbon . The wings are made of carbon as well with wingtips in glas construction with carbon spar !
The V-tail is made of 2 pluggable pieces and controlled by special covered bowden wires.
As known from the CROSSFIRE the ORCA will be delivered with all necessary accessory as well.

• exchangeable tips included in shipment !
• 2 wing construction variations(full-CFK 65g or 80g carbon fabric ) available !
• 2-piece wings and tails
• complete accessory including ballast and extensive CD !

Available colours:

As active competition pilots (F3B, F3F, F3J) with WC and EC-experience we constantly searched for suitable models.

But either they didn`t fit all our requirements or they weren?t available at the required time.
Since different models were needed for the above named classes our time quota for self-construction was depleted after starting a F3J-model project in teamwork.

Due to the fact that multiple model-concepts Modellkonzepte were still in development we needed another way to make these real.

Our concept includes the introduction of competition models of the classes F3B, F3F and F3J as well as suitable accessory for competition and dedicated spare time pilots.
In doing so our goal is to keep low delivery times!


This can be archived, among other things, by a mostly similar colour-design which enables us to keep most models available in stock.
Another positive side-effekt thats not just for competition pilots ist the fact that accessory can be delivered fast and at low costs.

After cooperation in design and aerodynamic layout on privat made F5B, F3J and F3K-models - the F3B-model Crossfire is the first result of our work among the new structure of AER-O-TEC !

2007 a new innovative F3J-modell arrives, the ORCA !
2008 all improved version of WC winning f3b model : Crossfire eVo !
