on the hobbyking 4 channel radio have a racheting throttle
XRinger  1 points - 10/8/2015
Does the throttle (ch-3 on the mode-2) have a limited range, compared to the other channels? People using the throttle for sail boats reported less servo movement range on channel 3. Post #294 ***********rcgroups****/forums/showthread.php?t=1051

said, it was built into the xmitter firmware, so that WOT would be less.. I'm wondering if this problem still exist on the newest (2015) V2 transmitters?

I am new to the rc world, bought a 250 racing kit with CC3D Flight Controller. Would like to know if I can bind this to the CC3D without hassle. Another question: the radio is 4 ch, but the receiver is 6 ch. Does this mean I can use the receiver with another radio?

MEG I can help with your second question. The answer is YES. The receiver is very handy. It works with the 6 ch ver of the above Tx and the Turnigy9XV2 and TGY-i10 (i6).

is this radio bind and play for a 4ch plane or i have to do some pc configuration?

Dario Yes it is Bind and Play. No PC need. This is a very simple Rc System. All you can do is reverse Servo (Switches on the front). (No Mixing at all).

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.
