Hello dude...can explain,the different things about mode 1 & mode 2...cannot switch to each other mode?i mean the mode is permanent?
 NewToHobbyKing 16274 points
The Throttle which is on channel 3 (lever with no spring) on Mode 1 that lever is on the Right and Mode 2 that lever is on the Left!. Most RC Systems can be converted!

Will this work with a delta wing plain?
 NewToHobbyKing 16274 points
Dean No. It does not have mixing. (Just servo reverse ). You could use an external V tail mixer or such.

 NewToHobbyKing 16274 points
Jagmeet save me and you the pain and get a Turnigy9XV2 or a TGY. (I was under the though all 4 channel will do QUAD as long a you have a Flight Control FC but have been told this RC System is not this Rc System you want).

Multicopters are expensive, complex machines & require a better radio than this.

For those who are tired of bad english and poorly translated instructions. Here is how to bind the MODE 1 radio system.

1. Connect 8 AA batteries inside your transmitter and leave it turned OFF.
2. Connect your Motor to your ESC.
3. Connect your ESC to your Receiver on Channel 3.
4. Connect your Bind-Plug to the BAT channel.
5. If you want to test a Servo, connect a Servo to Channel 1,2, or 4.
6. Connect any good charged Battery to your ESC. You should here a beep from your ESC (some ESC's do not beep) and your Receiver's LED Light should start blinking. The LED is hidden under the sticker.
7. While Holding down the Bind-Range-Test Button, turn on your Transmitter. After about 3 or 10 seconds the LED will stop blinking and you should be able to control your motor and any extra servos you connected.
8. If not try it all again. I found that turning off my Transmitter and turning it on helped reset any errors.
9. Give me points if this helped. :D

Excellent Product. Binding was easy, following Trance123 instructions. One note, you have to have an ESC to do the binding, as the binding plug takes up where you would normally plug the battery in. Once bound, you can then power up as normal.

Hobby King 2.4Ghz 4Ch Tx & Rx

It is well made and works well!
I have flown it at a distance of 500 metres with the range check button down & no problems.
Very good value for money
Oh so cheap, BUT it has twin receivers! This is almost unheard of in the lower priced systems.

I believe twin Rx to be very important. Why? Firstly I worked in the video industry for 21 years and it is common knowledge there that twin Rx is far more reliable in getting the signal through. If one Rx can't receive the other will.

To someone who is first time to 2.4Ghz you would need to look up the "binding" process on another manufacturer's site as there is no manual.
I am using NiMh AA's successfully in the Tx and these can be charged thru the input jack from your usual charger
