I have buy this TX, it works well ! But I have some questions : -Can we use the TRAINING port for simulator ? Use this cable : http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idproduct=9043 ? -Where can I find the cable to bind 2 radios for beginners ? Can we make this cable ? Thank you for response.

rcdragon (-75%)
no that cable will not work u need a cable which says input signal PPM.since it outs PPM signal at it trainer port.for using as simlator buy cable from ebay. search ebay-"simulator cable". i have used it sucessfully bye.

I would like to ask how many positions the 3rd and 4th channel have. 2 or 3 position? Im looking for a radio with 3 position channels. Hope I made myself clear! Thanks! :)

Hi, I'm totally a newbie in this, and just bought this radio, anyone know where can i find a manual or something to start with it?? thanks

Alexander (67%)
bought three or four such devices, and one refuses to work more than 50 meters.

shadowind (20%)
It works very well for me, receiver is cheap, but I am a little bit disappointed : This is a beginner radio, It will be good to have on-line manual in pdf format. And cables for simulator/ other radio connection (for teacher) ... even if the price is a little bit higher, have these possibilities will be perfect ! If it rain : simulator ! If you have to repair your model : simulator !! If your model is definitely HS : simulator !!! If you break your receptor on awesome crash : simulator again ! A few simulators are free as FMS : *******n.ethz.ch/student/mmoeller/fms/index_e.html ... instead of repair or rebuilt models every time and spend depron foam and glue, crash virtual plane is more ecologic and economic.

Hello,
Does this Tx come with a Tx battery? Does it include a charger? Can I use one of them 3S LiPO's especially made for Tx's for this radio?

Thanks in advance
Alex

kubo13 (42%)
No it dosnt come with Tx battery you must use 8 AA battery

alex4orly (61%)
Hello Kubo13
OK, but can I buy instead one of theose 3S LiPO that are here on this web site, instead of using 8AA Batteries?

Thanks again
Alex

klanert (58%)
Alex you can buy this one http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9787 it will fit in the battery tray (indeed it's smaller than the battery tray). woodbw explained in the product page how to replace the battery connector.

alex4orly (61%)
Hello Kanert,
Thanks for the tip, but I didn't get an answer, so I went and ordered - Rhino 2620mAh 3S 11.1v Low-Discharge Transmitter Lipoly Pack

Isthis NOT good for this Tx? Where is there an explanation on how to replace the connector?
Thanks again
Alex

Ron (72%)
No C tick, no FCC certification stickers on them any where. So if you want to use them at a club open day (or if the public has free access to your airfeild at any time) then as I understand it, you are not covered. However, they are ISM devices and so CAN be allowed to be used on your airfeild subject to your safety officer testing them and giving an OK. Generaly most clubs use a 'maximum of 5 or 10' such radios being use at once policy, and that by doing so you are giving the radios about 5 or 6 frequencies that they can go to. These are not frequency agile or multichannel radios. Turn them on and they find a frequency/channel and squat there. This is a big part of why they are cheap. They are great park flyer, ground model radios (trains, boats and cars/trucks).
Basically , if your plane is worth more than $100, stop being so cheap and spend at LEAST that much on the radio to control it!

alex4orly (61%)
Hi Ron,
Thanks for pointing this out. THose radios (I am going to buy 22 of them) are for a class at high school, where I have 22-24 kids learning to build a model airplane. It is only intended to fly in-doors in their basketball court at school.

What is the deal with the connector? Is that going to match what the Tx requires?

Hi

There is a big discussion on US forums concerning whether these 2.4 GHZ radios have the FCC certified sticker on the transmitter.

I have several questions

Are they FCC approved and stickered.

What is the sticker code on one of the transmitters.
Are they legal and approved for US use?

If they meet these criteria, there are a lot of US people going to be buying them, if not, they are illegal...and one should think twice before buying for US use as to be AMA insured , we must be flying a FCC certified transmitter/receiver.

aces54 (80%)
What do you mean illegal?? There is no laws regarding the use of hobby radios...do you think there are transmitter police or something? Just buy them and use them they're great! and if one of your club members says something, just tell him to piss off or he'll wear it, stand up for yourself and don't be a pussy.

Andrew,
Can this TX be set up for a Delta, or do i need a mixer.

ANDREA (56%)
will need a mix

Sumeet (74%)
Well, This systems are not specified for the use with mixers... see the product detail...

koupa (56%)
Is it possible connect the tx to the pc??

thanks

Sumeet (74%)
Ya but for programming only.... You have to buy a usb cable for that... Can'nt connected with PC for sims.....

kubo13 (42%)
Yes they sell cable and you can plug it with a computer

klanert (58%)
I don't know if you can connect for programming knowing that the cable sold here in HK is for the 6ch tx. You can buy separately a usb cable (can't be the programming cable) on the internet to use in the simulator. E-bay must have this kind of stuff

Ron (72%)
Cable is for Sim and buddy use only, the unit is not programmable. Servo reverse is by panel switches, no internal channel mixing, rates or anything available. These are a basic radio only.

Pour les francophones :
1- Mettre le câble shunt sur la prise Bat du récepteur
2- Brancher la batterie sur une prise servo du récepteur, le "-" vers l'extérieur
3- la led située sur le flanc en haut du récepteur clignote
4- Appuyer sur le bouton "Bind range test" de l'émetteur et mettre celui-ci en marche
5- Quand la led du récepteur reste allumée fixe, l'accord est bon, vous pouvez relâcher le bouton
6- Tout éteindre, enlever le shunt du Rx et brancher des servos et la batterie sur sa fiche après avoir allumé l'émetteur.
Cela a marché du premier coup pour moi.

Joran (39%)
Thanks for the answer beaufighter. I ´ll start looking for a Y connector. I will accept the fact that there will be the same deflections of both ailerons so the plane will probably yaw a lot more which i will try to compensate with more rudder.

rcmodelreviews. (86%)
You can create differential by having your servo-arms at an angle rather than parallel with the aileron hinge-line.

Alan (76%)
Hi Joran, that sounds pretty clued up for a newbee, thanks for the question though, i was wondering about seperate servos myself.I have a spectrum Dx6i that confuses me to bits and has broken 4 times in the 6 months I've had it. this is much nicer. cheers

Joran (39%)
Hi Alan,
iam a newbee with respect to modelgliders... I am a licenced 1:1 gliderpilot and also an aeronautical engineer so i ought to know a little bit about aerodynamics and mechanics :-)
good luck with the y connector, mine works fine on an easyglider with hardly any yaw side effect caused by aileron deflections.. My experience with the easyglider: rol the plane to the desired angel, next stick neutral (rol) and kick in a little rudder along the whole turn. Its like a 1:1 glider which seems no surprise.

7/05/2009
Joran (39%)
I am kind of a newbee if it comes to ailerons on planes but is it possible this Tx Rx system can operate the ailerons with 2 servo´s just with one channel on your transmitter (L-R on the stick). It kind of feels like this system isn´t capable of doing this...
Hope you guys can help me out

Beaufighter (-25%)
If you use a simple Y-connector, you may use two servos on one channel. If you want differential or some kind of mix (flapperons etc), you need one separate channel for each servo.

Sumeet (74%)
Ya that's right friend.... You can'nt use mixer with this radios...

Dennis (56%)
Are there plans for a 6 channel and or computer version???

I will be buying one if they do!!

jezevec (83%)
look here ***********hobbycity****/hobbycity/forum/forum_posts.asp?TID=284

Malfamartin (71%)
Why a 6CH when you can get a 8CH for 70$ + module 60$.

ngashok (52%)
Can the charging lead be connected to 240v AC or is it 110V? There is nothing written on the transmitter.

Mustang Sally (96%)
The transmitter will not show it. You will have to check the powersupply of the charger, this will normally state the input voltages it can accept. Additionally a 110V will have a different kind of plug.

ngashok (52%)
I meant there is a charging port on right side of the transmitter. What is that for? Whether it takes direct AC input?

ishady (63%)
It is for charging the (rechargeable) battery inside the transmitter.
But some guyz think its better to charge the battery outside the tx, using an appropriate charger, as a short circuit while charging will destroy the precious transmitter. My friend(s) learnt it the hard way.

Malfamartin (71%)
I will answer your question Ashok! The transmitter can NOT be charged from any AC current! You have to have a separate charger if you prefer. If not you can use 1,5 alkaline (std) 1,5v AA batteries, or rechargable 1,2v NiMh AA batteries. The nfollow ishady's recommendation.

Gerald (46%)
Very nice and simple tx/rx set. Would like to order a few for friend but the qty available shows -2. Any idea how quick they are replenished?

Best regards,

Ron (72%)
Charging socket is 12vDC, centre pin positive. It connects direct to the battery ve and -ve terminals internally. So what you should do is get a proper charger for whatever type of batteries you fit. NiMh would be best. Also, you only need 7.2V for the TX to work I have found. No range or battery life issues at that voltage. I use 6 x AA 2200mAh NiMh cells, and some brass rod for the unused battery places.

n6vig (56%)
"robot controlling hobbiests do not order!"

May I ask why?

Mustang Sally (96%)
Yes, you may.

Beaufighter (-25%)
It is simply because this system has no advanced features (actually no features other than servo reverse and centering adjustment), and HC don't want the customers to buy something they then complain about in forums worldwide afterwards...

ESTHER (56%)
Hi all.

I'm new to RC planes and have just received from HobbyKing their 2.4 Ghz. transmitter + receiver pack. My question may sound stupid but, does the receiver need it's own battery to operate? If yes, what voltage should it be? I thought that receiver would operate with the energy received when I plug the connector comming from ESC in it's throttle channel in the receiver.

Thanks a lot

Regards

Mustang Sally (96%)
Hi,
Normally it should get it's power from the ESC. What ESC do you have? Is it not working?
Regular power for the RX is 4.8V-6V.

Mustang Sally (96%)
Conncet the ESC to the throttle channel on your RX. This should work as a power input for your RX as well.
Follwo above instruction from Ishady/Albert for the binding. To connect the power to the RX simply connect your LiPo Battery to the ESC. You need to have the motor connected to the ESC for it to work properly. Be carefull with the propellor, it's better to have it removed while you make all your adjustments, the motor may start running during the process.

ishady (63%)
HI Esther (a female R/C enthusiast? but I could be wrong..lol).
If you ask whether the RX need its own battery, in my case: ITS NOT! Just plug your esc and the RX get its power from it too...in this case you have your own right reply...(seem no beginner at all).
For the binding procedure, I hope you dont have to bind it because mine (2 of them) dont need to bind to its original TX.

Sumeet (74%)
Ur question is not so stupid... Well, Reciever uses it's own battery (5v/2Amp) unless you use the besc(ESC with in built Battery eliminator circuit...) With BESC the receiver & motor will consume the power from single battery. But if only ESC, the motor & reciever,both will require one-one battery... thanks

mraha9 (51%)
how to bind this tx & rx... need some help since already buy extra rx

thanks

ishady (63%)
(Sorry, I quote below from Albert. Please give Albert a point, not me. Thanks).
=========================================================
Albert (49 points)
1. Install the battery to 2.46 transmitter and shut it down.
2. Insert the matching lines to the channel Bat port of the receiver.
3. Connect the receiver battery to any one of the channel- port, on the same time the two LED are flashing and this means the receiver are going to the match status.
4. Press and hold the button on the transmitter, and then switch on the power supply.
5. Observe the LED on the receiver, if found that the LED is not flash anymorc and that means successful matched. (This process about lOs)
6. Release the match button on the transmitter, take out the match line.
7. Install the server and then test.
8. If the tests fail, please repeat the action above.
9. If the tests success, then insert the power supply port into BAT, match complete.
The negative pin is on the short side of the recver.
E-mail me if you want the manual, it is for the 6 channel. The information is the same.

Samie (84%)
Could you please E mail me the manual your effort would be appreciated.
samiebell*dodo****.au

Philip (56%)
how can i use the Trainer system option? What do i need for using it?

ishady (63%)
This TX have no trainer option as it pointed at the specification above.
If you need trainer port, then this TX is not for you.
Please consider what you need before buying.

bdoets (84%)
What is the transmitting power of this TX?
Does it have a CE (European approval) sticker?

Edwin (62%)
Maakt t uit joh is maar een sticker

Chris (62%)
switched mine from mode 1 to mode 2 not to hard.

DIMITRIOS (53%)
The antenna should be in the boat or out of it?

peterp (69%)
I have the antenna inside the fibreglass hull of a sailing boat and not having any problems at all.

DIMITRIOS (53%)
Is it possible to use it in boats?

ishady (63%)
And why not, if I may ask?

Malfamartin (71%)
It can be used to manage a coffe maker too. The sky is the limit.

Chris (62%)
Thanks alot for the info Dominic!

ishady (63%)
Good explanation Dominic. It's the same with ordinary TX I think? Well, with my lousy hand, I already broke 1 TX...LOL.
Thanks again Dominic.

Marc (70%)
Has anyone tried to convert one of these mode 1 models to a mode 2? I really want one but mode 2's are sold out.
Thx,
Marc

Chris (62%)
I need to know this also, because I ordered mine before the post about the difference of the mode 1 and 2 and of course I got mode 1 but I realy want mode 2!!!!

Dominic (82%)
Remove all batteries. Open the radio, 4 screws at the back, and change the ratchet from the Elevator on the right to the Throttle on the left and the spring+lever from the throttle to the Elevator. Replace the jumper on the white socket to short the lower two pins. Thats it!
Warranty void! But no soldering or rewiring at all.I will post directions with pics on the forum later.

Marc (70%)
Dominic, thank you for the info. It only took me 20 minutes to switch it from mode 1 to mode 2 and it works great.

Thomas (56%)
I am also wondering about batteries for this system? What does it require?

peterp (69%)
Needs 8 AA batteries, would recommend chargeable batteries as the transmitter has a charge jack.

Petr z Brna (84%)
I use 3 Li-Ion batteries from Mobilphone Nokia. It is lighter,than AA batteries and endurance about 5 hours. Charging with service connector (for 3 cell).

Malfamartin (71%)
A very good idéa Petr! But it seem to be a bit expensive. I use a Rhino 1250 3S LiPo, of course with a big hole cut in the compartment. Added some fome on the printed circuit to snug fit. A Rhino 2620mAh 3S 11.1v Transmitter Lipoly Pack is also possible to fit in. Easier for one who can not solder.

MATIES (31%)
what's the diference between the 1 and the 2 mode?

Mustang Sally (96%)
Mode 1 throttle on the right,
Mode 2 throttle on the left.

John (87%)
Can you buy more then one receiver if you want to use more then one plane and not have too pull out the one reciever all the time and swap it over?

Mustang Sally (96%)
For that price...buy more sets. :)

John (87%)
You can only use one transmitter at time. Would you like me to carry 20 tansmitters at a time. Get a life Mustang Sally?

John (87%)
At least now you can buy just the reciever if one breaks by accident. Maybe United could be able to add it to there list.(Business sense) UP YOURS!!!

Alan (76%)
yes John you can bind as many recievers as you like to one TX, just remember to disconect batery from previous plane or it will be trying to fly in the back of your car while your out on the feild enjoying yourself and you won't be able to hear it. Can you guess how i learnt this? Cheers Alan

moon67 (56%)
Is it US FCC approved?

flyguy-matt (92%)
I think we are all missing the point here.lol.
Does it come with a battery for a start?

Malfamartin (71%)
I like to know what I'm missing!
You should check the discussion for Mode 2, where you will find that it is 8 cells 1,2 or 1,5v.

sunworld (56%)
2 questions please about the HobbyKing 2.4Ghz 4Ch Tx & Rx: - Is it a full range RC? - Is it suitable for V-tail planes (fitted with a V-tail mixer)? Thanks.

joemanner (80%)
Hi Rudolf

Please read the de******ion.

Multi Flapperon, mixer, vtail, FPV, robot controlling hobbiests do not order!

As you can read, no vtail-mixer

Regards

Jason5001 (4%)
It will work with a v-tail adapter, like the TURNIGY v-tail.

gazza2009au (76%)
no one has answered Rudolf's question reguarding "is it a full range" can someone please reply....

Jason5001 (4%)
Please define the term 'Full Range'.

CrashinDutchman (58%)
Full range - 1500 meter? The range, full or not, should be stated in the product description.

Ron (72%)
Full range is meaningless - too many factors to be considered for that term to have a usefull meaning.
The TX is an ISM radio, how far can the RX be away and receive a signal ? Tell me your conditions, what model, height of RX compared to TX, over water, wet grass, in the air (what altitude?) and I may test it out for you. Full range is 'sales differentiator' used by a couple of the big names to scare people into buying their radio.
And if you are going to try and run your model a mile away from your TX, let me know where so I can stay right away from your dangerous practices!
I can tell you 500metres is usable, and that it was done on a bare dirt paddock, TX held in hand (normal operation stance), RX on the ground in a 1/10 gas buggy and was done purely as a range check - I could not see the car well enough to be able to control it at that distance. Normal operation distance of that mdel is less than 100metres.

altronpower (65%)
Can you mod it to give a fifth channel?

Tarmo (88%)
like Futaba T4YF

Jason5001 (4%)
Wow, good idea.
Lets see if someone can do it and post details about it.
I would love to know if there are any hacks for this ultra cheap radio!

Dominic (82%)
Got mine today from HK. Inside seems like a 5th channel isavailable. Will check it out.

Petr z Brna (84%)
Inside is a port for switch 5th reversing channel, but a port for joystick i have not found.

Errol (87%)
What other receivers are compatible with this?
Also does it have a trainer port?

CrashinDutchman (58%)
Did you read the 'Key features' mentioned above? It says: Trainer system option.

Anthony J. (64%)
good radio love it!!!

flyboy314 (57%)
how far can this tx and rx go and will it work with windows 7

rcdragon (-75%)
trainer system available but which cable to use the usb cable is for 6channel one.

christophe (100%)
Hello everyone, i've purchased this item and want to upgrade it with Turnigy 1450mh 3S LiPo but don't know witch of the 3 plugs is the right one for connect with the Tx wires (I'm a newbie). if also one one you could tell me witch one is for the caharge and for the balance, I'll be less idiot for tonight *-) Tks
