I just got an FS-GT3B. So far so good, it looks and acts like a real radio. Very cool!
The manual is full of typos, though. I couldn't get my servos to reverse direction, and finally figurd out what the correct procedure was.
If they would put out a decent manual, this might be a terrific radio.
If you have one, you've probably found that the manual is full of typos, and the procedure for reversing servos (Page 16) doesn't work.
After a lot of fiddling, I figured out the correct procedure. At least, it works for me on my FS-GT3B.
-----------------------------------------
1.) Turn on the transmitter.
2.) Press the large, round ENTER button. The MODEL text will highlight.
3.) Turn the large, round ENTER button until REV highlights.
4.) Press the large, round ENTER button. The channel number will begin flashing.
5.) Turn the large, round ENTER button to select the channel number you want.
6.) Press the END button. The NOR (or REV) indication will start flashing.
7.) Turn the large, round ENTER button to select REV (reverse) or NOR (normal).
8.) Press the large, round ENTER button to save the setting for this channel. The transmitter will make a slight BEEP sound.
9.) This channel has now been changed and saved. If you want to change another channel, go back to step 4.
10.) When you have changed the direction of all the channels you wanted to change, press the BACK button to return to the opening screen.
11.) Now either turn off the transmitter, or keep it on and start your car to go racing.

Hope this helps!
