i want to make a flying wing so for servos which channels should i plug in
 NewToHobbyKing 15815 points
Vansh if you have this Rc System, already then you will need to buy a V-tail mixer to be able to use this Rc System in a flying wing. (If you do not have this RC System then get the HK-T6AV2 and cable.) On the Receiver you need to connect Ch1(Aileron) and Ch2 (Elevator). (This Rc System uses the same Receiver as the HK-T6AV2 Rc System). But the HK-T4AV2 needs a V-Tail Mixer ( TURNIGY V-Tail Mixer. Ultra-small PRODUCT ID: TR-V-tail. Around four dollars)

 NewToHobbyKing 15815 points
WTWUK I know this Tx use PPM but can I run servos from the Receiver as PPM or cPPM? I did not think so. Please let us all know if this Receiver will run servos in PPM mode. PLEASE!

Can this be used for multi copters?
 NewToHobbyKing 15815 points
Yes yes Ivan
 WTWUK 3851 points
This would be a lousy TX to use for multicopters. Not enough channel adjustment to enable the correct inputs. Once again NTHK, you are giving poor information due to lack of knowledge.
 NewToHobbyKing 15815 points
Yes I know what you are saying WTWUK. Yes I think the Turnigy9XV2 would be better or even the 6ch HK, In fact, if you bother to look, I say so below. BUT the question was " Can this be used for multi copters?" Not "Will this be a LOUSY Tx for a Multi. Sorry and I also say get a good FCB like the KK2.1.5 Please Ivan!

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.
