F3B/BUTTERFLY Block Diagram BUTTERYFLY “Fb”
Model Type Described
42 Fixed Wing Models
The F3B/BUTTERFLY type is intended for F3B
competition models. It can be used, however, for
other similar models. Depending on the external
switches connected, functions can be switched on
and off.
Beside two aileron servos, it is intended that two
separate flap servos are used. This allows mixing
flap  elevator and/or elevator  flap. Also the
combi and differential functions plus flap  flaperon
and V-tail mixers with three further finished coupling
functions. It is possible to extend the flaps downward
and both ailerons upward (Butterfly) and adjust the
elevator to re-trim so that when driving the pitch trim
does not change from that of normal flight.
Additionally, an airbrake can be mixed with the
above.
Also, without separate flaps, the ailerons can still be
used as spoilers or as flaps (flaperons) and also in
connection with the spoiler  aileron and spoiler 
elevator mixes.
