all information I have, is posted above. When I can get my eyes on more information, I will get it passed along to the Z community asap. :):):) So please be patient if your questions are not answered right away.

ICS will be used for dialing the speed control and steering servo.

Or if the new mini-z 2.4 module for the new Ko Propo radio will work in the helios ex-10. The photo's show a new radio that looks like it has the mars foot print.

Tell KoPropo guys are asking if they should hold off buying a ex-10 or not.

trying to answer....
from the info given above
a1:
Tire Diameter: (F)23.5mm (R)27mm
Tire Width: (F)9mm (R)12mm
and the pic... the front wheel/rim does look smaller (measured it with a ruler hahaha) although i may be wrong...
http://mini-zracer.com/forums/attachment.php?attachmentid=23338

usually rear and front rims/tires are of different sizes in the real le mans cars too...

btw... tire/rim sizes (from kyosho mini-z vol.2 optional parts list)
diameter of racing rims is 20mm while the tire diameter is 25mm
diameter of classic rims is 17mm while the tire diameter is also 25mm

classic rims are the type of rims you can find on the shelby cobra427,lamborghini jota, ferrari 512bb and the porsche 934...


a3:
from the info given above Width: 78mm... i don't know if it's the body width or the track width... so assuming it's the track width... i am taking an educated guess (again i may be wrong) that the rear diff may be a bit wider than the mr02... not sure if it is as long as the f1 diff though...

also the kyosho mini-z vol.2 optional parts list states that the widest track width is on the lamborghini jota at 76mm which has an offset of 3mm per rim (the parts list didn't list the track width of the enzo so i wonder...)

anyway i'm thinking having a rear offset of 4mm (on a mr02 diff will give us a track width of 78) might be too much and make the rim pretty susceptible or prone to breaking... besides from the picture in another thread, it visually looks wider...
http://www.rc-japan.de/BigPics/minizVergleich.jpg

i wonder if professor tim can confirm my answers, don't worry, i'm not in a hurry... :D

All KO Modules are pretty much interchangeable now. I wouldn't see why a new one wouldn't work with the old transmitters. I use an AD band module for Helios on my Mars R. THe Spektrum module is also for use with Mars/Helios as per Horizon hobby.

Either way, I'm finally getting a new Transmitter (EX1 Ur) hehehe! I hated the Helios case! Just too big for my hands. :)

hmm... selling the car alone with the "Transmitter: KT-18 (Sold Separately)" will probably be a really good idea... that way one can either choose to purchase the kt-18 or a module that will hopefully come out soon as well...

i'm thingking if you can swap out the old mr01/02 board with the newer 2.4ghz board... and how much would that cost?

but on the other hand it might be cheaper to get a 2.4ghz chassis kit if and when kyosho does have it in the offering....

i hope it's not a new diff.... one thing i love wbout he existing cars is the crossover of parts. i don't want to fork over another wad of cash for another proprietary diff. i will if i have to though :)

i agree, selling the tx seperatly is the way to go. funny how the japan market has been getting kits like this for a long time and we are just getting them now with this new system. better late than never :)

As far as I know the Spectrum is a complete different technology, and will not work.

KoPropo for as long as i can rememeber, their modules are backwards compatable for the most part. So I would hope for the same with their 2.4ghz system.

Tim Johnson
2007.10.17, 10:37 AM
I don't think any of you have caught on as to how your handling will be better with this car. The motor is lower and more center, so that will make the diff look bigger. It is the same diff as a MM MR-02.

thanks for that update Tim, It's on my list of wants. I'm still interested to see what the price will end up being.

arch2b
2007.10.17, 10:43 AM
yep, i saw your pictures of the new mm motor pod.

question: can this new mm motor pod be used for existing mm wheelbase configured cars/bodies or is it specific to the wheelbase for the le cars?

question: is the suffix 'LM' refer to a new rear motor mount configuration? or does it represent the LeMans series autoscales for this specific release? inotherwords, will this whole package be specific to LeMans series ONLY or will the electronics be compatible/find thier way into the base mr-02 and mr-015 and/or ma-010 chassis in future releases?

Tim Johnson
2007.10.17, 10:54 AM
The LM is for the pod configuration. "Low Motor" LM.

arch2b
2007.10.17, 11:44 AM
great, thanks for the clarification :)

we created a new subforum for the afs system and i wanted to make sure i was correct in my assumptions regarding the lm suffix not being tied to the afs system therefore not part of the title for the new subforum. not that you wanted to know any of that :p

here is the new sub-forum (http://mini-zracer.com/forums/forumdisplay.php?f=117)

tim just clarified.... as i suspected, it refers to the new low mount configured motor pod. think of it this way, kyo has NEVER added a suffix related to a body type. the suffix ALWAYS refers to the motor configuration.

me too... hehehe... so it's low motor... hehehe...

I don't think any of you have caught on as to how your handling will be better with this car. The motor is lower and more center, so that will make the diff look bigger. It is the same diff as a MM MR-02.
well i did suspect that handling would be a whole lot better... the video shown was pretty cool as well...

chassis improvements...
it will have the widest track width (78mm) and a long wheelbase to boot (102mm)... the tires are wider... 9mm up front and 12mm in rear...
the motor will be set lower to the ground and will be more centered...
the lm mount will be open at the bottom... this will help dissipate heat more efficiently compared to the rear pod mounts previously made by kyosho...
board will be programmable...

radio/tx improvements...
it's not only that but the radio which claims "Radio response speed increased 33%, compared to the KT-5"... and with the 2.4ghz glitching will be greatly reduced...

one point i'm concerned about is if it indeed uses the same diff as the mr02... rims, the rear ones in particular.. as i pointed out earlier, to have a 78mm track width, you would have to have a 4mm offset per rim...

widest offset is 3mm which gives us a track width of 76mm on a mr02 diff...
(the kyosho mini-z vol.2 optional parts list states that the widest track width is on the lamborghini jota at 76mm which has an offset of 3mm per rim (the parts list didn't list the track width of the enzo so i wonder... anybody have any info on the enzo?)

4mm offset might affect rim integrity, thus making it more susceptible or prone to breaking...

as we all still haven't seen the final product, the rim issue is still speculation... so in the mean time all we can do is wait... go back to our gardens and start planting more money trees in anticipation, and hope they flower & bear some fruit sometime jan-feb '08... :D :D :D

Draconious
2007.10.18, 07:48 AM
3mm Offset + 12mm Rims/Tires :) ...thus the new Super-Wide, larger diameter tires.

Was it LM that was used on the older readysets? I guess we can just conveniently forget those existed since they did not sell so well.. F50 body readyset etc... Or was that LR...

I want to know the size of the PCB... hopeing its a little shorter...

arch2b
2007.10.18, 08:30 AM
those were rml....

odd they would make 12mm tires vs. just making a 4mm offset wheel. now there is an entirly new range of tires to produce, etc.

i would suspect many will move to aluminum wheels. the 575gtc runs +3 and i continually break those wheels so i always run aluminum with that body. there are already +3.5 available and i'm sure it won't be long before 11mm wheels are made in +4 as well. i'd almost rather do that than haev to buy specific tires just for this car. it's enough to carry stock for the normal 8.5 and 11 with f1 front and rear in terms of my budget.
i thought the 575gtc had the widest trackwidth to date?

i can only suspect that you had better plant a bunch of those money plants :p nothing 'new' comse cheap, take the lit for example.

holy jeepers batman.... drac's cracked the egg... i totally forgot about the new rims/tires... definitely will make 78mm track width... good show ole chap (alfred in the background).... :D


i thought the 575gtc had the widest trackwidth to date?
the list i had (see attachment below) didn't have the 575gtc or the enzo.... can anybody verify/post track width of those cars?

Tim Johnson
2007.10.19, 10:30 AM
on the enzo the front is 72mm, and the rear is 76mm

575 Front is 75mm front, and 76mm rear.

current tire line up is 8.5mm 9.5mm and 11.0mm.

don't forget PNracing is currently selling that GTP body with extra wide offset rims. I dont know of any mass rim breakage, unless you nail someone the right way. But of course that will happen to anyone, with any body style.

arch2b
2007.10.19, 01:15 PM
i have not seen any mass breakage of major offset wheels due to poor design or construction.
i have broken 3 or more sets of 575gtc wheels during very heavy and constant use on my hfay cars. these cars are run about 3-6 hours 2-3 days a month. in all fairness, i've seen many other wheels break as well like mclaren, enzo, etc. during hfay racing as well. it's a demanding series and puts alot of wear and tear on your car quickly.

to clarify, kyosho is adding an adiditional line of 12mm tires to the lineup and corresponding wheels.

herman
2007.10.20, 11:25 AM
just a thought... will the board be available in the ma010? that way you won't be needing the lowdown crystal adapter... heck you won't need a crystal period... this will definitely give you more options on body choices you can run on the ma010... :D

there is no reason why you can't run these in stock class, as long as you conform to the motor rules. I will not be able to post any pictures of the car until later this month. Sorry guys.

Apparently the 2.4GHz boards will have 2x the capacity of "conventional" FETs. Not sure if "conventional" means 3004's or 3010's...

The smaller diameter front wheels and tires means new steering knuckles with the axle in a lower position.

due to advertising language, that means nothing essentially.
The smaller diameter front wheels and tires means new steering knuckles with the axle in a lower position.
the 3010 were advertised in a similar manner and unitl we can verify the fet type and qnty, verbage is just that. please let us know if you find out more:)

are new knuckles confirmed?

ruf
2007.12.26, 08:48 PM
Yes new knuckles are confirmed, but I can't see how they would do any good in any other application, since they would raise front ride height using normal wheels and tires.

ruf
2007.12.27, 09:52 AM
Nothing "special" per se, but the axles are lower in the knuckle to allow for the proper amount of ride height with the smaller diameter front wheels. It's almost impossible to tell from the picture, but it's described in the 5th detail shot. The caption reads something like:

"Matching the new front wheel and tire, the front knuckle also has a new design. This design ensures enough suspension travel even with the Le Mans body which has very little front clearance."

It also looks like they finally started inverting the spring perch like we've been doing for years... :D

I'd like to know about this as well, I was on the Atomic website a while back and noticed that when they showed pics of they're MR-02's the spring perches were mounted inverted.. I'm assuming it makes the front suspension smoother in some way...

color01
2007.12.27, 05:01 PM
Inverting the spring perch takes out one more moving part from the suspension, thus less friction to deal with. ;)

You could use the knuckles with an old MR01 motor pod and make an MR02 rally car. :rolleyes:

ruf
2007.12.27, 06:56 PM
Yup. I think it centers the spring better, which also contributes to smoother suspension action. It's theoretically less unsprung weight, but that's negligible.

in motorcycle racing.... unsprung mass equates to 2x the mass of sprung mass
granted it is only a minimal part but in a racers mind....minimal is better than nothing :D
and it also does reduce friction due to less moving parts ;)
