Will this work with a delta wing plain?
 NewToHobbyKing 16158 points
Dean No. It does not have mixing. (Just servo reverse ). You could use an external V tail mixer or such.

i am new to hobby ....can i use it for quads??
 NewToHobbyKing 16158 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).

Hey experts, I am very green to the rc airplanes and the terminology used in this. I found a Brushless Pitts Special eRC I like in the PNF section but it requires a TX & RX. Is this control up above the RX and TX I need? Or if there is another product I have to get just please let me know. Thanks.
 NewToHobbyKing 16158 points
Grant if the Pit is "PRODUCT ID: AT-Pitts " with 4 Ailerons then the Rc System here, is able to do the job but it is just enough. (The Turnigy9XV2 would be a lot better and will move to your next plane far easier). Also the Pit is not a beginner plane, so if you have not flown much, please get a Trainer (Hi Wing).

I have 5 of these still going strong out of 7. Never had any issues with loss of signal. Great starter Tx-Rx. I have the TGi6 now, best on the marke fo the prprice. I have 7 Rx's bound and she has all the bells a whistles the much more expensive ones have.

Hi would this work for a slope soarer?it has a futuba pcm fm 40 my 8 channel receiver installed
 NewToHobbyKing 16158 points
Garth it can but you may or will need a external V-tail. (a Turnigy9XV2 or HK-T6AV2 with cable would be much better). You can get a V-Tail Mixer here! ( TURNIGY V-Tail Mixer. Ultra-small PRODUCT ID: TR-V-tail. Around four dollars)

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
