Hi, New to RC - building a boat and this system seems ideal for what I need, The motor is a stock standard 6V DC motor. I know I will need a servo for the rudder but do I need anything else to regulate power to the motor if I get this kit (not sure if there is a requirement for something else between the RX and the motor). Also do you have a recommendation for a servo - Regards Darren
 NewToHobbyKing 14311 points
Darren to control the motor you will need a ESC (Electric Speed Control) of some sort. If the Boat cam with a motor it may have a ESC. Servo depends on size of boat?

Hi Im planing to build a bait boat for fishing and I wonder if this radio going to do the work.I need a range of at least 150m and for propulsion am going to use 2 water pumps and I need them to work independent so..Im going to need 2 esc for that,and any advice for my build???
 NewToHobbyKing 14311 points
Jovan I have proven 300m (in air / line of sight ). You will need to remove one spring to have 2 throttles. (left and right). Throttle in (on a mode 1) on the right. You may have issues getting reverse as well! I do think it is all doable.

Hi consideration given! But the Turnigy9XR looks like a great controller with some nice features. How does it compare to the 9XV2 for my application?
 NewToHobbyKing 14311 points
K Town if you have this RC System and a Laptop (Better still a Surface Pro 3) then they are as good as the Turnigy9XV2. If you have flown you will know that you will always need to make changes to your setup. The Turnigy9XV2 is easy to adjust anywhere (at home or at the field). The Hobby King 6channel is easy to adjust at home!
 NewToHobbyKing 14311 points
So sorry this is the 4 channel. It is a BASIC Rc System. You cannot mix. It has simple reverse only. The Turnigy9XV2 is much better. Sorry for above I was comparing it to the 6 channel.

Hi I am totally new to this. Is this remote suitable if I am wanting to build an RC hovercraft? I am wanting a versatile remote to build various things with, and will start with the hovercraft. Any other remote in this price range could work better for my needs?? Thanks folks!

K Town Guy the 6 ch is better (but you need the cable). Better still is the Turnigy9XV2. Please consider!

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
