We celebrate 20 years of AER-O-TEC with a new facelift Edition of our F3B-legend CROSSFIRE-1.
Alexander Omith Horn was testing the new version in F3G-competition and ended in 5th place overall
2023 in Contest Eurotour F3G !

the new details are making the model even more easy and precise to fly - a joy to use it in competitions or all day flying on the field or slope.

The chosen arrangement of the aileron- and flaplenghts in connection with giga flaps and the neutral hingeline results in a neutral steering with very good agility for perfect and firm distance- and speedturns.
The optimized hull-lenghts contributes to this as well!

Outstanding directional stability (distance flight) and circle-flight characteristics (thermal flight) are made possible by the incomplex adjusted X-tail.
Who ever flew the same model once with a X-tail then with a V-tail knows what we are taking about!

Last but not least the elementary wing airfoil with 1,7% camber that already works at low wing loadings.
The included 800g brass ballast ( ballast-space in wing ) is usually enough even in heavy wind !

The moderate profile thickness of 8,3% allows harmonic handling and a wide trim-area.

• simple V-shape
• 2-piece wing
• crosstail

Nevertheless or maybe therefore a racy appearance.

.

Especially well done is the design of the fuselage which together with the X-tail is a distinctive identification characteristic.

This is supportet by the chosen ing:

In F3B team performance is a critical factor.
Therefore we wanted to improve our own performances by sharing a common model.

Naturally the use of a common model also simplifies the infrastructure and logistics within the team.
Besides using the same ropes and winch diameter, the direct experience exchange while testing setups and ballast-experimentation improves.
This results in benefits in competition-flights!

A careful optimized concept adjusted to actual requirements of F3B was designed.

The F3B-model: Crossfire!

• Central attribute of the Crossfire is the wing airfoil M1783 by:
  Max Steidle.
• Design and aerodynamic concept by:
  Stefan Eder.
• Realisation of the concept for a CNC-moulding cutter by:
  CAD-CAM OFFICE.

The airfoils by Max Steidle proved themselves at F3J, F3K and F5B-models for the last years.
Among other things this profile is in use by top-pilots of F3J and F5B at World- and Euopean championships.

A global spread of these M-profiles took place by the ESCAPE of Jaro M?ller (EUROMODELL) at which also Stefan Eder made the design and Max Steidle made the airfoil!

In fact, the Crossfire should have already been deployed at the end of 2003.
But the search for a suitable producer was pretty tough.

After the model-revision a on the F3B-area experienced producer which exclusively fabricates this model in the desired quality could finally be found.
