Futaba's 6J Six-Channel 2.4 GHz S-FHSS Radio

Written by Jenni Oregbaugh As featured on page 67 in the December 2011 issue. Read an abridged summary and highlights from the article.


The Futaba 6J Radio System is an asset to any type of aircraft flown whether the pilot is a beginner or more advanced.





The trainer switch is on the left side of the transmitter. When the 6J is used as the instructor transmitter and the trainer switch is activated, the model is controlled with the signals from it, and will work with a Futaba FASST or FHSS transmitter.





The control sticks can be adjusted to make it comfortable for the modeler to hold and operate the transmitter. The stick tip can be turned counterclockwise, while holding the locking piece, to lengthen or shorten the stick.





Shown with the included R2006GS receiver and the switch harness, the Futaba 6J is an affordable radio system at less than $200 with high-end programming functions and modes.





The center knob on the transmitter controls flap trim and hovering pitch fine-tuning. Both functions are inhibited until turned on within the function menu. The knob can also operate a sixth channel.





Uncluttered, clean, and simple, the Futaba 6J faceplate is easy to navigate. Minimal buttons and a large LED screen make it easy for a beginning modeler to learn how to use a transmitter and fly.





The data input lever is used to change the values of various functions, including changing the model name, setting dual rates and exponential, and fine-tuning the trim. Below data input is the select key, which displays the submenus and values for the current function.





The trainer/buddy-box micro-type cord input is on the back of the transmitter box and easily accessible. The 6J can be used as either the instructor or student radio, with three modes available, depending on the student’s ability.





The large LCD screen is easy to read. The main screen shows the model name, type of model, battery voltage, model memory, and whether it is S-FHSS or FHSS mode. Programming functions and settings can also be viewed and changed.





The throttle-cut function is offered in two versions: NOR (Normal) is used for internal combustion engines, while ESC (Electronic Speed Control) is used for electric-powered models. The throttle-cut button is easily accessible, at the top left-hand side of the LCD screen.





The R2006GS S-FHSS receiver, shown connected to throttle, elevator, and rudder controls, is on a diversity antenna system, which maximizes the signal reception and allows the modeler to fly trouble-free. It also adapts to the transmission mode (S-FHSS or FHSS).
