PDF Manual

I was looking to replace my old FM radio system with 2.4ghz.  In searching I found a really inexpensive option.  For ~$69 at my local hobby shop, I got a 3 channel programmable radio system with a ton of features.  The manual was written in “engrish” but if you’ve ever own a programmable radio before then terms like end points, trims, etc, isn’t that foreign.  For most applications like RC vehicles all you’ll need is 2 channels (forward/backward, left/right).  It does have a 3rd channel (AUX) that is basically an on/off button.  Might be useful for hovercrafts to turn on/off the main motor.  You can also use it for turning on lights on your car too.

The receivers were very inexpensive as well.  I bought 5 of the receivers (FS-GR3A) for my nitro and electric cars for about $15 each.  With 2.4ghz, I don’t have to worry about other people interfering with my radio.  Good bye to crystals.  You just have to bind the receiver with the transmitter and you’re set.  You no longer have to worry about other radios around you with the same channel frequency.

The interface takes a little bit to get used to but it has everything you would ever want in a radio.  To enter the menu, press and hold the dial button, then you’ll get a list of options.  To move between options, you can push the buttons above the dial or turn the dial itself.  To get out of the menu, press and hold the dial button again.  There are a ton of other buttons on the transmitter which I never use.  It’s definitely not the most intuitive interface but it does the job.  If you ever want to rename the models, it’s a real chore.  But for the price you really can’t complain right?

How to bind the RX (receiver) to the TX (transmitter):

1.  Plug bind plug into CH3, turn on car, the LED light should flash
2.  Hold down bind button on transmitter module while turning on the TX
3.  The light should go steady now
4.  Let go of bind button, turn off car, remove bind plug, turn off TX
5.  Turn on TX and then turn on car, it should be bound now

Here are some features:

LCD display
2.4ghz and FM (extra module)
8 model memory slots
E-point (aka EPA, end-point adjustments, travel adjustments)
Servo Reversing
Subtrim
Exponential (FlySky calls it, ARC)
Dual Rate
ABS
Steering Delay
Throttle Delay

You sure get a whole lot of features for your dollar.  If you’ve never had a programmable radio before, then this could be a bit confusing.  I would advise downloading a manual from Spektrum for their DX3(r) radios and read that.  Get use to the terminology and concepts. It’s pretty much the same, except, Spektrum may call it travel adjustments or EPA (end-point adjustments) whereas the FS-GT3 manual refers to it as E-point.  ARC instead of exponential, etc.  Same thing, just lost in translation.  For most people, all you really want to know about is servo reversing, EPA and maybe (sub)trims.  Everything else is fluff.  If you’re coming from a non-programmable radio, you’ll know what trims and servo reversing is.  As you get more into this hobby, settings like dual-rate/exponential/etc may come into play.

The FS-GT3 comes in a nice box with transmitter, a receiver, and a bind plug. If you ever feel like going back to in time, you can also buy a FM module so you can control your other FM receivers too.  I like how the steering knob swivels out.  It uses your standard 8xAA batteries.  I modded my FS-GT3 to use rechargeable lithium polymer batteries now.  See here.

I use this radio with all my RC cars.  From my nitro buggy, on-road electrics, and brushless F1 and buggies.  I love it.  People think I paid hundreds for it.  It’s a pretty sexy pistol-grip radio great for bashing around.  Looks great and cheap enough to not worry about it.

Please take note that there are newer revisions of this radio system.  The one from DealExtreme looks like a newer version. The new ones use a different 2.4ghz module, FS-TM002.  There are also new receivers, FS-GR3B, FS-GR3C. FS-GR3C has a fail-safe built-in. The new receivers won’t work with the FS-TM001 module.  You can tell by looking at the receiver, there should be a button next to the LED.  This is for the fail-safe setup.  It returns the throttle to neutral when radio signal is lost.  Unfortunately, V1 of this radio doesn’t have it. :(

    3 channel, what’s the third channel for?
    any mixing function available?

  • ken writes:

    The 3rd channel is AUX. It’s just a button for on/off. You can use it for whatever you want. No mixing functions.

    I’ve never had a problem with it. A very good radio for the price. Especially when bashing around at the park.

    Hi Ken.
    Was wandering if you have used NimH batteries in say the 7.2 range?
    I have one of these on the way and have read there’s something up with these not wanting to pass that type of voltage which means if it won’t use 7.2 I’ve got to set up a totally different motor and ESC system for my car.

  • ken writes:
    February 14th, 20109:35 pmat

    The battery for the car has nothing to do with the transmitter.

    You can use 8 nimh AA batteries (9.6v) or 8 alkaline batteries (12v) for the transmitter.

    Hey, Ken!
    I’ve just received one of these today, only it’s been mingled with by the guys at Eurgle(not much changed, they just replaced the branded stickers and slightly modified the pictures in the manual.
    Thing is it came with a USB adapter and a link to a pdf on r2hobbies as an instruction manual.
    Ive seen that the flysky also has drivers so that i can adjust and set my rx directly on my pc. Would you be so kind as to tell me where i can get the drivers from, as the flysky site link is flawed…

    Thank you!

    Hi Robert,

    My FlySky GT3 didn’t come with a usb adapter. Does it plug to the DSC port? I’d curious to see how it connects or what it looks like. If you can post a link to a picture that would be great.

    I edit my settings on the TX itself.

  • ken writes:

    Hey Ken, I have the FlySky GT3 Transmitter. I also have the FlySky FS-R6A Receiver. I was wondering if you knew how to get the Transmitter talking to this Receiver or if its possible because I’m having trouble with ti. Thanks.

  • ken writes:
    March 26th, 20108:19 amat

    I don’t think I tried… the GT3 and FS-TH9x uses the same 2.4gz module though so in theory it should work.

  • JD writes:
    March 26th, 20108:25 amat

    My biggest question is that the Receiver came with a Bind Key but on the Receiver it has 7 slots and they are labeled Battery, CH1, CH2, etc but no Bind. So I’m not sure how to get them to bind. I found the Receiver’s Manual online (http://www.planemodel.com/zz-01/FS/6ch24gradiomanualen.pdf) but it talks about Matching Lines and I’m not sure what that is exactly.

  • ken writes:
    March 26th, 20108:37 amat

    On the TR6A, the BATT slot is the same as the Bind. Just plug in the bind plug there. At least from what I remember when I sync it to my FS-TH9x, I put the bind plug in BATT. Hope that helps.

  • JD writes:
    March 26th, 201010:08 amat

    I looked on the Pictures that you have of the FS-GT3 and the FS-TH9x module and they say Model: FS-TM001. My FS-GT3 module says FS-TM002. Could that be why the Transmitter couldn’t communicate with the Receiver or is it just another model?

  • ken writes:
    March 26th, 201011:03 amat

    Yeah looks like they changed it with the new ones? if you can’t bind then looks like it won’t work. I’ll see wif I can bind my TM001 TX with the TR6A RX when I get a chance.

    Please take note that HKGT2R CANNOT BIND with this transmitter (FS-GT3). Initailly read this post and bought 3 HKGT2R recievers from Hobbyking. However, none of them can bind. Is there any way to force them to talk?

    Hi. Did you get the hk receiver to work with the FS-GT3
    I had some FS-GT2 receivers but they would not bind.
    Thanks

    I managed to bind the FlySky 3CH receiver to a FS-TH9X. It should be the same one as this on Hobby King, GT-2 2.4Ghz Receiver 3Ch, http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idproduct=10625&aff=166047.

    There are reports of binding the 3CH receiver to the Hobby King T6A 6CH transmitter. So the 6CH RX’s should be compatible too. I use the 3CH RX’s for my elevon planes. Light and extremely cheap at about $6.

    Hi there, i just got my GT3 today. I set up the reciever for [model 1] no worries, its a top transmitter.
    I got a 2nd reciever for my 2nd car too, i changed the model to [model 2]and binded the new reciever. if i have both recievers powered up, the both react to the transmitter… is this normal? i thought it would depend on what model i have selected in the transmitter menu. Or are the different models to select the different settings on the transmitter???
    Thanks in advance for your help.

    I think this is normal. If you bind it to 2 receivers and have both of them on. Then yes, both will respond.

  • ken writes:

    Looks like they changed the receiver, they never had that fail-safe button before.

    Hi,

    I have a FS-GT3 with FS-TM002 Transmitter and FS-GR3C Receiver with failsave.
    The problem is that the servos are not running smooth. (3x HITEC HS-5945 MG)
    They make jerky movements even at very close distance between RC TM.
    It’s become more bad when i increase the distance (3-4 meters)!
    All Batteries are fully loaded and binding was done like in the manual.
    Can you help me with that?

    thanks

    Tried the Lipo mod and my radio went “poof” as soon as I turned it on. I have converted 2 Airtronics radios to lipos with no issues. Battery voltage was 12.36 which I guess is more than this radio can handle. Has anyone else fried their radios from installing 3s lipos?
