Does anyone here have a gryo installed on your MR-03? I am thinking of getting it and and I'm interested to hear what people have to say about it.

i do,it works ok on smooth floors but not so good on high grip like rcp:)
works great in my drift awd
so 03 with gyro can drift or not?

the idea behind the gyro is to keep the car stable while racing.
For drifting the idea would be too keep you from overdrifting.
The unit can make changes but how dramatic I dont know.
I may pick one up to see if it can keep me off the rails when Im racing.
It will teach me how to control my car.....

I have one but it's not installed.
I have driven an MR03 with Giro it feels good much more comfortable to drive at NYRC. I wouldn't say it makes me go faster.
Apparently there are ST. Gain and TH. Gain on ICS Manager you can adjust to suit the driving. I'd say get it.

Can you still adjust this even if you are using a KT-18? (sorry, I'm new to 2.4ghz)
Can you still adjust this even if you are using a KT-18? (sorry, I'm new to 2.4ghz)
You program it in the car (via ICS manager), so it is not a function of remote. So it will work with the KT-18...

you will need to get the ICS cable in order to change the ST. Gain and TH. Gain on the ICS Manager...if u want a cheaper version, please refer to My F/S Thread (http://mini-zracer.com/forums/showthread.php?t=33296) :D

Wouldn't that feel weird when you are diving because it might over correct when you are trying to correct?
I am wondering if anybody knows if it is legal in events? (races)

At our Winter Cup Race, on the carpet track, the only MR03 had the gyro instaled and he finished 4th, behind 3 MR02's ( the second one still 27Mhz ). The car was box stock ( just tires changed ) and I drove it a bit with gyro and felt it more planted then without, which was almost undriveable.

No.... it's the same as 1/10 RC cars.... there is just not enough mass to the car to get the momentum that's needed to drift with 2WD.... you can pretty much ONLY drift with a 4WD car (in RC)

I also installed the gyro recently on my 03. The car was set up for my local track, and I installed it during a qualifier. No change. I kept it installed, but disconnected the plug, and still nothing. Is there different settings? Do I need to hook it up to some sought of special software? Or did I just blow $60 bucks?
akura2
2010.03.12, 08:54 PM
Well if your car is already hooked up, then you won't see a difference... the gyro is mainly designed to correct steering inputs on less-than-desireable racing surfaces... you will only really notice the gyro working if your car is prone to spinning out....

The gyro has steering gain and throttle gain in the ICS manager.
If you max out the throttle gain, the car will cut throttle in the corners. Makes the car quite slow. If you max out the steering gain, the steering wheels will correct quite a bit for fishtail, but in a tight corner, you will not have enough steering.
With the setting somewhere in the middle, the car is pretty stable. On a bumpy track, there will be less tendency for the car to move around in a corner. It will make the car easier to drive clean. It will certainly help mask a bad set-up.

FYI
controlling the Gyro gain (steering and throttle) is ONLY for the dNano cars... not with the Mini-Z 2.4

Are you sure? In the MR03 ASF manager there are sliders for steering and throttle gain.

I have the Gyro for the 03 and used it with ASF manager 1.01 and st. and th. gain is part of the settings that work. Also, benmlee is 100% correct. I will add on a track with very high traction the Gyro may help especially if you don't lose control of the rear end (car flips before sliding). On a high traction track I end up reducing the the st. gain and th. gain from default, because the correction from the Gyro slows my corner speed, on a lose track I may increase the st. gain by 5 or 10 and test drive until I find the right setting. If cleaning your rear tires (K20 threaded :D) with WD40 does not reduce your loose rear end then the gyro may be needed. In short the Gyro help stabilize the car, but like benmlee stated it may cover a bad set up. I will continue playing with.

There is a Kyosho PDF for the ICS manager that shows a screen for the 2.4 and a screen for the dNano and underneath it says the settings for the gyro ONLY work for the dNano.., i'm on my iPhone right now so I'll post a link to it when I get to a computer... The software may have been updated since that PDF... If it DOES work, then disregard my post... And sign me up for a cable for my MR03 with gyro

Look at post #20
the software used for the MR03 is the "MR03 ASF manager 1.01"
the software your talking about is for the MR02 and Dnano only and yes only the Dnano can use the gyro option with that software. But for the MR03 you have to use a different software (MR03 ASF manager 1.01) and if you have a gyro installed then yes you can use it to your liking

thanks.. like I said earlier, I could be wrong and this could have been a software update that I hadn't seen yet
the part I was talking about was on this page:
http://www.henimo.de/vario_download.php?id=41
and it's on page 9 where it states "*Function only available for the dNaNo FX Series" and it shows both programming screens...
like I said also.. if it IS true (and we've seen that it is) I'm getting a cable ASAP for my MR-03 with gyro
Thanks for the info guys... outside of my dNano, this is the first 2.4ghz Mini-Z I've owned (MR-03 Sauber) and I have 6 "regular" AM mini-zs including the elusive first generation Pro-Z (from back when no-one could seem to be able to get chassis they ordered)
once again... thanks for the info

I know they are listed differently... but they look identical

is the MR-03 Gyro the same as the dNano gyro?
hmm... good question... was doing a search to find out if it was asked before, then i came up with this thread... i was about to ask the same thing... :D
can anybody verify this? and can anybody please post a pic of a chassis with a gyro on? basically to show the orientation of the wires... reason i'm asking my brother bought me one... it didn't come in the original kyosho packaging... and the instructions are missing... so i'm wondering if it's really a mr03 gyro or a dnano gyro...
it kinda looks like this... (picture taken from nanotrax which basically deals dnanos... so i'm inclined to believe that it's a dnano gyro)
http://t0.gstatic.com/images?q=tbn:0EL0KAGMsSKVxM
and it doesn't have the ko propo etching on the back like this...

will take better pics for sure... if anybody has both gyros would appreciate a side by side picture... thanks :D

I actually run my MR-03 gyro interchangeably on my dnano and my MR-03 and it works GREAT on both!!
the wires for the MO-3 Gyro are a little longer, but that doesn't matter.. I have space under my body for it to fit

2010.06.09, 10:46 PM
thanks for the info akura2... will the dnano gyro work in the mr03?
anyway, here's a better picture of the gyro in question...

comparing it to other gyro's, when connected the wire's orientation is...
chassis front end <--- black white red ---> chassis rear end
http://www.nanospeeders.com/photos/mr03chassis.jpg
whereas my gyro is...
chassis front end <--- red (+) white black (-) ---> chassis rear end
as seen above...
don't know what the orientation of the original ko propo gyro is...
can anybody help? a bit cautious of putting it in as i might fry to board, or the gyro, or both...
thanks...

additional info from kyosho's online manuals...
dnano gyro (http://www.kyosho.com/jpn/support/instructionmanual/dnano/pdf/dnw107_dnano_gyro_unit_m.pdf) mentions gyro wire orientation is...
chassis front end <--- black white red ---> chassis rear end
however.... mr03 gyro (http://www.kyosho.com/jpn/support/instructionmanual/mini-z/pdf/MZW405_MINI-Z_Gyro_Unit_m.pdf) doesn't mention any orientation of wires as it isn't indicated on the instruction sheet...
wondering if anybody can confirm the pin orientation of the mr03 for me... thanks in advance... :D
akura2
2010.06.10, 01:03 AM
When I tried it out, I thought the orientation was weird too... but my friend Lito threw caution to the wind and plugged his MR-03 gyro into his dNano and it worked... so I did the same, and lo and behold....working like a charm... now, the other way around... I'm not sure.. but the ICS programming works, and on the track it works... no function reversing or anything (as you would prabably expect)

2010.06.10, 02:16 AM
@akura2 - pretty cool...
@ub0211042 - thanks for your reply... hmm you mean no polarity issues? kinda find that a bit weird...
anybody else use a dnano gyro for the mr03 or the mr03 gyro for the dnano?
so based on the pictures can anybody identify if my gyro is for the dnano or mr03? :D
i'm a bit tempted now... but it will be a very expensive experiment if it fails....
apart from kyosho, are there any other 3rd party gyro's produced for the dnano / mr03?

hey akura2 / ub0211042 can you please post a picture of your respective gyros :D

Herman,
1) MR-03 gyro and dnano gyro are the same although dNaNo version from Kyosho lists for more (and costs more wholesale). My customers have proven these are the same as we run both cars at the shop
3) Another manufacturer for gyros is "X-power" which some shops carry. You can search it

That's why Litp and I bought the MR-03 Gyro in the first place.... and then we got Dnanos and we were like... "hmmm.... I wonder..."
he was more bold to experiment though... LOL

ok... ok... drum roll pls....
i did it... tried it out and... whallllah.... phittt zitz... kaput... a trail of white smoke emitted from the chassis or gyro or something... ended up frying??? scratches head in wonder....
not!!!! hehehe... it worked!!!! but couldn't tell if it is really worth while at the moment since i just drove it on smooth tiles... it didn't seem to have any big counter steering movements as compared to the mr03 gyro system video seen on youtube... (http://www.youtube.com/watch?v=THYBrzSyDaE)
i'm still thinking that it's the dnano gyro... probably the default settings for the dnano gyro and mr03 gyro are different??? can anybody confirm the gyro settings for each?
a big muchos gracias to all who replied... :D

I recently bought MR-03 Gyro to play around some slippery floors at home.
herman is right.. The steering correction is not as big as shown on some youtube videos. Overall the car became more stable but the gyro assistance is minimal I would say and I end up a little bit disappointed.
Then I made myself ICS cable following THIS (http://mini-zracer.com/forums/showthread.php?t=31464) thread. It works and the default MR-03 gyro settings are:
ST.GAIN: 90 (out of 255)
TH.GAIN: 60 (out of 255)
(the dNano defaults are ST.GAIN:128 / TH.GAIN:128)
After playing with the ICS settings I made the car handle better. Maxing out the ST.GAIN and middle TH.GAIN worked fine for me.
Overall the Gyro unit without an ICS cable is not as useful as expected.
Adding ICS cable makes it great toy to play with :D

I have both MR03 and dNaNo gyro. They are exactly the same except the length of the cable, whereas the one for MR03 is longer. I've tried to put in the one for dNano to MR03 but found that even though I can fit it in, the cable is very tight and I wouldn't recommend it. On the other hand, fitting the one for MR03 (with longer cable) for dNano is not a problem at all. So, they are interchangeable and functionally the same.
Latest ASF Manager software version is 1.13
http://www.kyosho.com/eng/support/instructionmanual/mini-z/miniz_racer.html
Regarding the usefulness of the gyro, here is my view.
1. If the car has been setup properly for a particular track, you may not need it. But I would still recommend putting a gyro in as you can always tune down the ST and TH gain ratio to minimize its effect most of time when you are racing flawlessly. You'll be glad you have the gyro to function whenever you make a mistake.
2. If you are new and don't want to spend too much time tuning the car for a particular track, the easier solution is to put a gyro on. But the catch is it'll be slower for corners if you don't tune the ST and TH gain ratio using ICS.
3. For very slippery track, a gyro is a must.
Just my 2 cents.
