F3B/F3F-model Crossfire-1

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.
