Nice! Which gyro is that and how exactly do you tune it? My friend bought a heli gyro to try and help his drifting, but it doesn't work very well at all.

you can get them on Ebay for like $20 or so.(ek2-0704B)
This is the one that i got BUT you will NEED a Third Ch for this one.

for usen just your 2ch radio you would want this one
ek2-0704 for 2ch radios you cant turn it off.(but its hard to find this one now)
http://www.helibuy.com/images/helicopters/ek2-0704.jpg

For My radio all i needed to do was....
just plug it in to Ch1 on the RX
the yellow wire to Ch3 on the RX
Flip the switch on the Gyro to REV

turn on the Rc.. Wait for the Gyro to set its self about 3 seconds


on my Tx my datarate for ch3 is set to 28%

!!!! DO NOT GET IT WET !!!!

unless your good with electronics you Could take the Gyro apart like i did and Coat the boards in it COMPLETELY
with Epoxi
i even covered the Delay and Limet controles with epoxy.
i set the gyro limet to full and delay to its lowest BEFORE doing the Epoxi waterproofing.
DON'T cover the NOR / REV switch as you might like to still use this at some point in time.

this is the Epoxi that i use to waterproof with

Dont mount the Gyro in the CENTER of the Rc!!
Here is a photo of my Chassis and you can see were its mounted at.

His looks just like that first one but says Hobbyking on it. I didn't know what the 4th yellow line was for, but I guess it's for the 3rd channel port. He just got a 3ch radio, so everything should be good to go! Thanks a lot, hopefully it will work as well as yours.

let me know how it works for him..

I don't understand this. I looked at the manual and it appears that the connector with the yellow wire JUST has that one wire in it, and it's a signal wire, not power or ground. What happens if you don't look it up? Hooking it to an unused CH3 receiver input seems redundant.

From your directions, it appears that the red/black/white cable carries the corrected servo signal and power and ground.

I could understand the need for the yellow wire if that was the one that needed to be inserted into CH1 (steering).

the Chinglish "manual" :rofl:
the Gyro will not lock unless you have the yellow wire on a Ch.
and is for the Gyro trim...
the gyro takes its trim data off the yellow wire and will not initialize without it.
even if you don't use Ch3 on your Rx it does have data on it
as long as the gyro can see data on the trim line it will initialize
you just wont have control of the gyro and how it works.
if I use my 2Ch TX on this Ch3 data is +100% by default
and the Gyro is Crazy sensitive and i have No control over it.
but i use my 3Ch TX All of the time.
here is how its set
http://a5.sphotos.ak.fbcdn.net/hphot..._6262528_n.jpg

the ek2-0704 gyro is a Basic gyro and don't have a trim line
you can only set or control the sensitivity by the control on the gyro
Hence you can use it on a Rx with only 2Ch

The ek2-0704B is a Pro gyro with trim control.
yes a "default" mode without hooking the yellow wire would have been nice but no such luck.
But you have More control with the trim ......
you can control just how much Gyro you want from No Gyro to Crazy sensitive
just by setting the Ch3 Data rate and trim.
on mine i have my Limet set to MAX
Delay set to its MINIMUM
and the Switch set to REV

I hpoe this was a help to ya..........

great post, i have allways wanted to try a gyro, for $20 i cant say no

I'm Not Sure How It Would Hold Up Under Hard Bashing (Stock Like It Is)

My Gyro Is Filled With Epoxy
So I Don't See Water Or Vibration Hurting It...
As I Have Been Jumping And Crashing With It And It Still Works Just Fine.
And When I Say Crash Its More Like Major Whiteout 40+ At The End Of The Street Turned The Wheel To Quick And Did A Barrel Roll That Flipped It About 10 Times And It Turned Into A Cartwheel For Like 7 More Flips
Across The Intersection At The End Of My Street.
It Even Landed Back On Its Wheels And Drove It Back To The House Here.
The Only Damage Was 4 Big Cracks In The Body.
And The Gyro Is Still Working Fine.
So It Can Take The Stuff That I Dish Out To It.

So what exactly does the gyro do in a land vehicle?

hpi was first to venture into land based gyros with it's "d-box" drift assist system. It just helps the vehicle to auto correct and continue in it's intended direction. Basically automatic counter steering.

It'll help you go straight on a slick surface like gravel or loose dirt, especially in a rwd vehicle. It can be tuned like the Dbox, I think, to help you drift as well.

it just helps you in steering and AWESOME for (Drifting)
you let the Gyro do Most of the Correcting as its A LOT faster than you could Ever be.
it keeps you pointed in one direction for the most part.
you can see in the video when it was turned off a few times on the curve the tail would just come up around to the front ....
Plus Under Full throttle takeoffs the rear of the truck would slide one or the other direction it will help keep this to a minimum..
I am not saying that the gyro will KEEP you from spinning out will be a 99.9% improvement .

ALL spin outs START Before one Even starts notice it or See it
and the Gyro is on the job BEFORE you even notice it correcting.

the video is a little drawn out at the start as i had a few people
saying that the gyro would mess with you on a hill or flipping in the air
but as you will see it don't.
sorry about the LOW audio in this Video
the mic on the camera is Under the tripod mount.

will say this it DONT Help you learn not one bit IN FACT it makes it harder for you when you Dont use it After usen it.
and with it you can do things you CAN'T do without it
I dont think there are alot of people here that can take that turn in that driveway at 20+ on lose stones and Holes .
A a human being can not Respond that fast.

built an autopilot for one of my professors (college credit for playing with an RC plane FTW!) and it had all the gyros, bells, pitot tubes, gps, and whistles. Pretty sweet stuff.

butterflies rainbows open meadows and bunny rabbits :love:

yep it is kind of cool to do things that most people would not do.
and don't think you should do
or do things people say will not work.

that is how we learn what can and can not be done
and to find a way that it Can be done .

just remember this most of the inventions we use on a day to day basis were a mistake
or a failed attempt at something other than what they were trying for
Or Got ridiculed for doing what thay felt was a good thing and would work.


If man went by the "book" and Never tired to do something they were told would not work or would be useless ..... remember these
The horseless carriage / Automobile
flying machine / the Airplane
The Auto gyro / Helicopter
Penicillin
and the list goes on for a Long ways

"most" of the people that tell you things like this have No first hand experience on the matter
they have only hear say then try to preach it like its gospel fact.

Hey radioman, glad to see this thread. I have been wanting to put a gyro on my savage. I was thinking to put this on my truck since I can get one for quite cheap ~$30

http://www3.towerhobbies.com/cgi-bin...?&I=LXVA42&P=7.

I prefer the reliability of futaba as compared to esky. Do you think it will work?

Cool
Im not shure just what the benefit would be in a 4x4 MT as i have not tryed it
in Mine yet..
My Main concern is how that gyro would hold up in a MT if you start Bashing with it ..
and my other concern is this...
"This gyro performs best when used with non-Digital servos."

and cool it only needs your Steering Ch1 to work you will not be able to control
the Gyro on the "fly" from your TX but will work.


$30 looks to be a good deal i would say what the hey and give it a try .....
just Remember this .
Never get them wet
and Gyros Don't like vibration and strong Shock.

you can help by usen epoxi on it
just coat the boards inside it ....
after testing it out and getting it all setup and adjusted you then can coat EVERYTHING on the Gyro cover the Gain control and all ....
just dont cover the FWD / REV or your AVCS switches

Even if you dont get it wet the Epoxi will Aid in maken it more Solid
and help protect it from vibration and shock ....

Just remember these Gyros were Built for helicopters not our land based Rc's so
they were not built to take alot of vibration and strong Shock or water.
The Epoxi is a Good Quick Solid Fix for this ....

well I will shut up for now just let me know what you have done and how it works for you.
Thanks.

Thanks for the reply radioman. I was wondering if normal piezoelectric like this http://www3.towerhobbies.com/cgi-bin...?&I=LXKTT2&P=7
would be better for car use? The one that I showed uses electronic sensor. Which one do you think has higher reliability?

I don't really bash my MT, just want something to help with my bad driving skill.

do you have a 2Ch or 3Ch radio system?

if you have a 3Ch just get the one like i have
a dude on the Blitz forum just got His today

Well I got my gyro in and all I can say sweeeeeeeet it is way to much fun I wish I would have done this a long time ago.
problem is I can not hardly drive with out it now If I turn it off I'am all over the place owell I guess I well have to put one in all my rc's like I said it is way to cool .Thanks radioman for the idea .
thanks for all the info an help made it real easy to hook up.

This is the one i have and use.
ek2-0704B look here you can get it for like $20
http://shop.ebay.com/i.html?_from=R4...All-Categories
http://i.ebayimg.com/00/$(KGrHqR,!h4...-MhFw~~_12.JPG

but if you have only a 2Ch

get the first one you posted ...

or the one i posted

ek2-0704 Not the ek2-0704B
http://www.helibuy.com/images/helicopters/ek2-0704.jpg

I have 3 channel radio, futaba 3pm fasst. I know the e-sky works perfectly but I prefer the reliability of futaba stuff and I can get this stuff quite cheap.

its your call.....
"reliability" is out the door when used in a land based Car/Truck..
A "out of the package" Gyro will not last long No matter what Name is on the label.
Unless you do something to Make it last.

But get the one you wish to get
I can link you to some that are $200 or more if you wish to have a name brand .
Thay ALL do the same thing.

All i Do know is i have BEAT THE HE!! out of this one with No Glitches or Problems.

good luck to you in what ever one you buy .:great:

Hey radioman, do you think it would be possible to use the gyro to counteract traction rolling?
Mount the gyro vertikaly and set it so it gives a short steering impulse into the direction the truck is leaning into?
So for example, if the chassis leans right, over 30° or something, while steering left, the gyro gives a steering imput to the right until chassis lean is below 30° again?

May lead to a few contacts with the track boundary, but shouldn't be a problem for an SC? Better than rolling over and waiting till someone puts it back on it's wheels.

Im not shure Hmmmmm
the guro dont react to a lean ...
it only reacts to a pivot on one axis and cant be set to react at a certain degree
But by what you are asking you can try the Gyro with the Switch in NORMAL
and see what that does
with the gyro set upright "wires up top"
it just might work .:great:

#1 with the switch in normal if you pivot LEFT Gyro would turn the wheels LEFT

#2 with the Switch in REV and pivot LEFT the Gyro would turn the wheels RIGHT

Radioman, maybe you should try this on your truck..

i dont need that.......

I just need to put like NASCAR Roof Flaps in the roof of my car
to keep the car on the ground.

The wind gets under the Body and i end up with a blow over.

so i bought the ek2-0704B but when i set it up with my dx3r in my traxxas rally all i get is a slow flashing led on the gyro, and clue what did wrong? lol, i fallowed your instructions, sorry i haven't tried a gyro on land before and I'm alittle lost

could it be the stock non digital servo thats the issue?

I know Nothing about the dx3r Tx

the yellow wire is on Ch3?
and your tx ch3 needs to be on when you turn the rc on.

"For My radio all i needed to do was....
just plug it in to Ch1 on the RX
the yellow wire to Ch3 on the RX
Flip the switch on the Gyro to REV
Turn on the TX

turn on the Rc.. Wait for the Gyro to set its self about 3 seconds"

if the gyro DON'T see a signal on ch3 it will not initialize .

well i have tired it with 2 diffrent radios and many diffrent servos, the best i have gotten out of it that been alittle servo flutter then nothing, i think i may have got a bad one

so its not dong Nothing like the one in the first part the last video i posted ?
