Can you please tell me exactly which receiver is compatible with this transmitter? I'm confused!! Thanks
 NewToHobbyKing 14081 points
Eduardo I do under stand. This is a 4 Channel Rc System but comes with a 6 Channel Receiver. It is cools in one way. So the receiver it comes with is :: " Hobby King 2.4Ghz Receiver 6Ch V2 (SKU: HK-T6A-V2) . That said it also works with HobbyKing®* ™* GT-2 2.4Ghz Receiver 3Ch (SKU: HK-GT2_RX) and Turnigy 9X 2.4GHz 8Ch Receiver (V2) SKU: RX-9X8Cv2). Also FlySky Receivers. I hope this helps!

How do you bind tx/rx hobbyking radios?
 NewToHobbyKing 14081 points
Rob the bind is very easy but takes many works. (This Rc System comes pre bound so try it first). You tubes has a great video on how to bind so please have a look there too!

1. Install the batteries in the transmitter. 2. Insert the jumper to the Bat port of the receiver. 3. Connect the receiver battery to any one of the channel- ports. Note: LED’*s flashing meaning the receivers are going into bind status. 4. Press and hold the Bind button on the transmitter, and then switch on the transmitter. 5. Observe the LED on the receiver. When the LED stops flashing, the bind was successful. (This process about 10 seconds) 6. Release the Bind button on the transmitter and remove the jumper and receiver battery. 7. Install a servo and receiver battery and then test. 8. If the tests fail, please repeat steps 1-7.

Great product, easy to bind and great range/response.

just because some people were having trouble,

1. connect the Rx to a Battery notice the blinking led
2. hold down the bind button on the bottom of the controller
3. turn on the controller while holding down the bind button and watch the led
4. when it stops blinking you are done (less than 5 secs for me).

1. Batteries in transmitter, switch off.
2. Connect one side of the bind plug to the BAT slot on the receiver.
3. Connect an ESC (with battery attached) to one of the channels. Black line (-) goes to the far right. You will see a red LED blinking.
4. Push and hold down the bind button on the transmitter while switching on. Keep the bind button held down until the red LED stops blinking. You are now ready to enjoy your wonderful new 2.4GHz TX.

After a range test the club members were impressed by its performance. Hand signals to confirm its function were hardly seen on the end of the test so we stopped it. No servo-vibrations were noticed during this test so the signal stayed clear overall. The 3 test flights afterwards only confirmed the first experiment. Five stars for doing its job but what a pity no instructions are available.
Very pleased with this purchase.

Awesome price! I love this radio and I also got 2 extra receivers. I am flying indoor and the receiver case can be easily removed to save weight. I also have another 6ch USB computer radio that binds to these recievers and workd with all 6 channels. Hobby City needs 6ch mixing version.
