Hello I am still looking for a 6 Channel 2.4 GHZ Radio that will work with the 3 Racing LED light system.

3Racing site says this;

This system is only effected by the transmitter. It is suitable for the transmitter which band width between 5 to 20 ms.

I think the Futaba 6EX will be good, But..

I cannot tell after reading a lot about the specs of the Futaba 6EX what its band Width is..

Can you help me find out exactly what its operating band width is?

or know where I can find this info out?

thanks I appreciate the help.

 
Ive got the 6EX instruction manual right here in front of me and i dont see anything about the operating band width, that I can find anyway. Maybe give Futaba a call.. 217-398-8970
 
"thumbsup"BUMP!!!!

Still searching !!
Cannot find anything!!! :shock:

Need NEW 6 channel bad but need to know band width before buying.!!!!

Contacted Futaba but need to wait for reply.

I'm Just wondering if anyone else may know any info on band width's of a few different 6 channel transmitters?

thanks all.!!

"thumbsup"
 
the newest Fut 6EX is 2.4 Ghz band. but what they are talking about on the band is the Framerate i believe (how fast the info goes from the TX to the RX via the 2.4 Ghz band). Think of frame rate like it was water in a hose. a small flow of water is 25ms, and a larger flow of water is 5ms. so you get more water in a shorter time at 5ms (5ms is faster than 25ms (milliseconds).

so with that said, im pretty sure the light setup will work as long as you program the channel correctly wiht the 6EX. im only guessing though.

i just got a 6EX for flying, but havent bought an RX yet but will very soon. though maybe not soon enough to confirm you question.

but with that said, the 2 light controller units i have work great on my React 2.4 Ghz radio. just need to program the channel and set it up correctly, so i wall ASSuME that it ll work np.

copied from the Futaba site on the 2.4 6 EX

Standard Programming Functions :

Model Select – six model memory.
Model Type – select airplane or heli programming in one transmitter.
Servo Reversing – on all six channels.
Dual Rate/Exponential – for ailerons, elevator and rudder.
End Point Adjustment – fine-tunes servo throws on all six channels.
Digital Trim – stores trim settings for each model for aileron, elevator, rudder and throttle.
Fail Safe – a safety throttle setting in case of loss of transmitter signal.
Battery Fail Safe – moves the throttle to a preset position when the airborne pack reaches 3.8V.
Stick Mode – choose from Mode 1 through 4.
Range Checking – Power Down reduces transmitter output power for up to one minute, allowing range checking from 50 paces away.
Changeable Throttle Stick – select ratchet for airplanes or smooth for helis.
Adjustable Stick Length – choose the length that suits your flying style.
Airplane-Specific Programming Functions:

Wing Mixing – for flaperon, flap trim, V-tail and elevon.
Trainer System – with the transmitter as either the master or student system. Compatible with other Futaba systems.
Throttle Cut – pre-programmed for safely shutting off the engine.
Programmable Mixing (1 & 2) – two different mixes allow any two channels to be combined.
Helicopter-Specific Programming Functions:

5-Point Normal and Idle Up Throttle/Pitch Curves.
Throttle Hold – for autorotation.
Revo (Revolution Mixing) – mixes rudder and pitch together.
Gyro Mixing – two gyro gain settings can be programmed and selected during flight.
Swash to Throttle Mixing – corrects slowing of the engine's speed caused by the swashplate.
Swashplate Types – choose from 1S (independent aileron, pitch and elevator servos linked to the swashplate), 3S (120° CCPM), or 3E (90° CCPM).
Swash AFR – Adjustable Function Rate, for use with 1S, 3S or 3E swash types.

that is sort of good news.
check below and see if you can help?





Here is what I wrote Futaba.

Hello my Name is Brian,
I am looking for specific information on the Futaba 6EX 2.4 GHZ radio before I purchase.

I would like to know the transmitter band width of the Futaba 6EX.?

I ask this info because I need to know if this 6 channel remote will work properly with the 3racing LED light system.

on 3racing website it states this below.
"This system is only effected by the transmitter. It is suitable for the transmitter which band width is between 5 to 20 ms."

So if you can please help me to find out if this remote will work with this LED light kit I would be grateful.


thank you

Brian


here is there reply


Thank you for your recent e-mail.

Your servo has three wires in its lead. One is ground (the voltage reference), one is Vcc, and the third one is the signal lead. Vcc = 4.6-6.0V

The signal is a square pulse of 1.0-2.0 mS wide that repeats every 20 mS or so. The width of the pulse determines the position of the servo, with 1.5 mS as the nominal center. The amplitude of the pulse is from the reference level to Vcc.



What does this mean?

will it work or not?

just wondering if you can help me de- encript what he said. lol

I am not getting it.

3 racing said between 5 and 20 ms

the Futaba guy said the radio is between 1.0 and 2.0 ms and repeates every 20 ms or so?

does that mean yes it will work because it repeats between 20 ms or "so" lol

or no it will not work because its bandwidth is between 1.0 ms and 2.0 ms
?

help is GReatly appretiated haha .
my trucks LED's are at a stand still ? :(

One way or the other is all I can get .
stinks
bad.




P.S. Also 3 racing sent me this after asking a similar ?

Dear Brian,
Thank you your inquire.
The LED system is don't work on Spektrum DX6, It can work on Futaba attack .
If you have any question,please feel free to contact us.
Best Regards,
Your Friend @3Racing


This doesnt help me because I do not want to use a 4 channel futaba attack! haha

Pretty sure the 6EX will not work based on the response from Futaba. Basically, in a Pulse Width Modulation (PWM, read this article http://en.wikipedia.org/wiki/Pulse-width_modulation) the width of the pulse determines the servo position. For example, the width of the pulse at full left throw is 1.0 ms. At full right, 2.0 ms. At center, 1.5 ms. The the 3racing LED controller as I understand it, recieves an input (pulse width) from the radio, and turns on a light mode corresponding to the position of the input. I am afraid that the largest pulse width of the 6EX is smaller than the smallest pulse width that the 3racing LED controller can intrepret. This is how I am intrepreting it.

Keep in mind that with a faster responding radio, the pulse width will be smaller, and occur more frequently. You may try and see if an older FM 6ch radio will work. Contact Futaba and get their specs on the FM systems that were produced a few years ago. This is probably why the Attack will work, older, slower, technology.

ok good sounds advice.
I agree.
maybe the 2.4 GHZ is too new lol
and to fast.
:-(

So maybe i will have to go back to a older radio and go back to a long antenna. :-( thats the suck part. haha


also its probably bad to use those old air remoes for ground controlled trucks right?

what frequency do i need to look for when looking into older 6 channels??


if anyone knows of any other remotes like the spektrum or futaba that is new tech and may work let me know?

pS. I was told this by "thatguy" he found on a heli forum.
But I have yet to confirm.

dx6= 22ms
dx7 se =11ms
dx3r 4 to 9 ms



so a DX7 SE maybe be a fun new toy .
if I can confirm it I will get it and just save up.

I was thinking I can use the 7th channel to put a cutoff in between the blinkers so i can turn them on and off so they dont keep blinking when i crawl. lol :shock:

Yeah send an email to Spektrum, the PWM signal they use to communicate to the servos is no big secret. I hope you get it figured out "thumbsup"
 
...I don't think they're actually talking about signal pulse width, but rather the frame rate.

"The period labeled "A" is called the frame rate. In the example it is repeated every 20mS (50 times per second), which is quite typical for most radio systems." http://www.rc-cam.com/servotst.htm

For the DX7SE:
"Feature: 11-millisecond (ms) frame rate (standard DX7 frame rate is 22ms)" http://www.spektrumrc.com/Products/Default.aspx?ProdID=SPM2731

For the Futaba 10C 2.4 GHz:
"For info, the pulse output on the receivers is unusual on these (apart from being only 2.8 Volts and with a frame rate of 72 Hz [~14 ms])..." http://www.fightingrobots.co.uk/cgi-bin/discus/show.cgi?tpc=59&post=103051#POST103051

For the DX3R:
"Three different frame rates can be selected via the DX3R’s menu, further tailoring the feel and responsiveness to your liking. The 16.5 and 11.5m/s frame rates are used with analog servos, while users of digital servos can take advantage of the lightning-fast 5.5m/s frame rate." http://www.spektrumrc.com/Articles/Article.aspx?ArticleID=1712

You want to be looking for the frame rate. The DX7SE will work (frame rate at 11 ms); however, the DX7 (regular flavor) will not (22 ms). The DX3R will work on any of its three available frame rates (16.5, 11.5 or 5.5 ms).

Find out what the frame rate or frame frequency is on the 6EX and you'll know your answer.

Frame rate in miliseconds (ms) = 1 / (frame rate in Hz) * 1000, by the way.

Cheers.
 
But the LED module will output different light modes according to a given input correct? If this is true then the frame rate does not matter, the frame rate is the update frequency between the radio and receiver. I think that we need some clarification about how the 3racing LED kit works.

I believe that the frame rate in question is that between the receiver and the servo, so it does matter.
 
that is sort of good news.

on 3racing website it states this below.
"This system is only effected by the transmitter. It is suitable for the transmitter which band width is between 5 to 20 ms."

My understanding is band width (or pulse width) is the critical parameter, not frame rate (time between pulses).

Well, I understand that's what it says, but I don't believe you will ever find a servo that uses anywhere near a 5ms to 20ms pulse width. That implies they are building a product that can't be used with 99.99% of the radios out there, which makes no sense.

If you look at the definition of 'bandwidth' on Merriam-Webster.com, it talks about two things: firstly being a range of frequencies on which a unit operates or communicates, and secondly being data transfer capacity.

Based on that, to look at a servo signal in terms of 'bandwidth,' one would have to talk about either the capacity of the data transfer rate (the amount of data that can be contained in a unit of time - in the example of a 20ms frame rate, it would be one signal per 20ms window, or 50 signals/second), or the frequency on which the servo and receiver communicate, which, again, is going to be 50Hz for a 20ms frame rate.

Again, I thing that we need clarification from 3racing on what exactly their paremeters are. I see the point that you are trying to make, but we do not have enough information to make a call on wether it will work or not. Unless someone comes in here with a working system with a radio that we have some PWM information on, someone needs to get in touch with 3racing.

Fair enough. :roll: Hehe. "thumbsup"

Hi Whoodie,

the Futaba 2 channel T2PH I have works and 3racing told me the futaba attack works.
but as I am looking for a 6+ channel these are no help.
but maybe something in the specs will help determine something.
I agree with you we need to know more about the 3racing LED system.

I have no problem emailing them.
they did reply to me once.


What should I ask them in an email that will help figure out what there LED system will work with.?

if you can help me word the email to them, or write one as well with me maybe we can get to the bottom of this little device and make a list of compatible remotes.
