Flier 1987 I wish but sadly NO! If you wish that then the Orange Rang Hobby King sell is DSM 2 / X compatible. The is compatible to what you wont.

What would I need to purchase to connect two of these together for training? And would it be compatible with a JR transmitter? Thanks
 NewToHobbyKing 13936 points
Grant if you want it to work and be simple then go Wireless Buddy Box System 4CH (Dual RX Controller) (SKU: DUAL-RX4-01). This saves any DIY and it will all work with your JR.
 NewToHobbyKing 13936 points
Grant this Rc System is not compatible with a JR but may be able to be buddied with your JR. I like the option above because you are not joined to your student!

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.
