|JR XF421EX Radio System|
|Computer radios offer many advantages over
their non-computer analog counterparts. But there are
still those who are reluctant to give computer radios a
try, mainly because of the complexity involved in
programming them and their higher cost.
Now JR is offering a computer radio that's simple to program at a price that rivals many four channel analog systems the XF421EX.
As easy as 1, 2, 3
JR's XF421EX makes setting up an airplane as easy as 1, 2, 3. It features an accessible two button input located at the top right and left of the transmitter. That's right, only two buttons are used /needed for programming. Your thumbs naturally fall into position on the buttons, which can be moved up or down. The left button is used to select the function (up) and to select the channel (down) while the right button increases or decreases to the value. Both buttons are clearly marked as to their function.
Reverse - Press both access keys up to enter the
programming. Now press the left access key up to select
the servo reverse screen. Pressing the left key down will
select each channel while the right key will reverse that
Guess what? You're all done programming, and you're ready to go fly! It's that simple!
This whole programming process takes about five minutes. That's less time than it would take to adjust the linkages of an airplane using a non-computer radio. And being able to make precise, minute adjustments (even at the field) at the touch of a button (or in this case two buttons) makes fine tuning the flight performance of your airplane a big advantage.
