Futaba's FASST (Futaba Advanced Spread Spectrum Technology) shifts very quickly virtually eliminating signal conficts and interruptions unlike other 2.4GHz systems that only stay on one or two frequencies. Dual antenna diversity enables FASST system to automatically and seamlessly select the best reception between the two antennas built into the receiver ensuring that the aircraft stays under constant control of transmitter regardless of altitude. Newly designed Dial-N-Key jog dial with joy stick button allows cursor movement in four directions for very user friendly navigating through menus and programming.
Modeler can change from the default mode (mode 2 in USA) by holding the Mode and End keys and then turning transmitter On to access the STK feature, changing mode and turning transmitter Off and then On again. It is recommended to send transmitter to the Futaba Service Center to change switch operation.
