TX Abbreviation of the remote control unit. "Transmitter"

Thanks for responses, I'll give this a try and be patient. Since I'm a newbie to all this, I do have a question about what Tx stands for?

CJ, Welcome to the forum! Congrats on your purchases and we hope

you have years of fun. Hint: This will NOT be your last purchase!

The G in the model # means the heli is equipped with an on-board gyroscope

that provides you with a more stable flight by keeping the S107 balanced

in the air. Early models did not have this feature and were known simply as

"S107". The G was added back then to differentiate between the versions

with the gyroscope and those without. Now that the gyroscope is a standard

feature, the heli is now known as an "S107" again, it's given the

gyroscope is built-in. The older paint schemes don't have the G painted on

the hood, even though the gyroscope is there.

   As for binding goes, what you are experiencing is normal. I agree that

the owner's guide is aweful, Syma needs to fix that issue (Hello Syma,

we know you read this forum!) Best bet is to keep the Tx swith on "A"

all the time unless two people are flying at the same time. There is no

selector switch on the heli. Turn on the Tx, then the heli. The green light

may blink indicating the Tx is communicating (binding) to the heli.

SLOWLY left stick up on the Tx, possibly several times, until they

bind. Then the light will stay green. If you fly more than one heli with the same

remote, you have to do this each time, only takes a few seconds and some trial

and error. It's a learning curve thing. I say SLOWLY left stick up because if

you hit it too hard and the units are already bound, you'll send it through the


   Good luck, hope this helps and please post often!

I bought a S107G a few days ago, all went without a glitch, excellent bird. So I am no expert but I do know what it feels like to wait for an answer.

I just chose A on the AB switch on the controller and followed the instructions, had to wait a few seconds for the bind to be effective. I am sure you have already charged the flight battery and made sure the Tx batteries are ok.

Do not get discouraged, the G will give you plenty of entertainment. Best of luck.

What causes the blinking green light. The manual in box is of no help. It says to set the band selector on transmitter and helicopter but doesn't explain where or how to do that. This is my very first helicopter and have no clue how to trouble shoot. Is there a difference between the 107G and the 107, I bought one of each. I'm experiencing this problem on both. The one worked fine, then I turned off and tried to get the 107 to work and got blinking controller. Went back to 107G and now controller also blinks and won't work! Need help....}
