F3B/F3F-model Crossfire

CROSSFIRE eVo ( F3B : single carbon )
TECHNICAL DATA :

This is the latest version of our successful F3B-WC-winning competition glider Crossfire :

New full carbon fuselage with longer tail boom and v-tail angle of 102 degrees.

new flap and aileron geometry with additional giga-flaps.
wing prepared for rds-systems ( available optional )we deliver also several servo frames...!

new design of carbon canopy for better handling when holding the model in front of wing.

available in standard f3b lay-up ( 80g carbon ) or double carbon ( 80g +68g carbon layers or 68&68 carbon for ultimate f3b performance )
all the proven features of CROSSFIRE combined with the latest experience from f3b-competition !

2009 update on famous CROSSFIRE f3b :
Model consists now of X-tail fuselage with new Crossfire eVo wings - called "CROSSFIRE classic" !
Available in "F3B"-Carbon construction or "exteme" double carbon construction !

Linkage of aileron and flaps is possible in standard linkage or rds-system !

Also available in well-know Crossfire design as shown below !

Demanded was a agile model with neutral flight qualitys for maximum results in speed- and distance flights.
Good natured handling and an airfoil also suitable for slow flights should allow mastering duration flights.

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.
