Hi , i am using hk-t4a for a long time. After a winter break, i ve taken my quad from the garage. But there is a problem: I cannot arm my quad. When i get the stick to bottom left position nothing happens. I made receiver test, everything is OK, calibration is OK... What may be the problem? Any idea?..

The throttle isn't spring loaded but otherwise it would be good.

Vin yes 8 x AAs Side by Side (Either one use or Rechargeable ). Turnigy AA Ni-ZN 1500mAh High Voltage (ready to use) (SKU: 91690000030 are great. Or you can go LIPO: Turnigy 1450mAh 3S 11.1v Transmitter Lipoly Pack (SKU: T1450-TX-3) will FIT!

I've been using this transmitter for all sorts of projects over the last few years. Most recently along with the Turnigy v-tail mixer for my small 30" wing

JC that is the answer. Use her on only one model and then I would never of worn out my programing socket on the back. THANKS nice video!

OOPs but if you were using a 6 ch that would work too!

The 4 channel has no programming socket. As you said, the 6 channel does. You could use this one on multiple models by using the switches on the front to reverse channels where necessary. I have a 9x for most of my models and a 9xr I use for my FPV, but it's nice to have this one that I can throw in the car or lend to a buddy.

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.
