The katana 120 is a acro 3d airplane from sebart.
the raccomended setup wak an hacker 10s motor and battery.
i ve been modified the set up and lot of part of the plane, ive reduced the weight from 7.5kg to 7kg, whith all pull pull servos etc.
whith this setup i can do hard 3d for lot of minutes, and lot of really precise pattern/f3a manuvers.
this setup is the best for me because is very light and very powrful.
