Kyosho serious about 1/10th?
Not at all, Kyosho is SERIOUS about WINNING and OFFERING the best to you guys whatever the class........ Therefore some of Kyosho employees and drivers are quiet and work on their side/own to bring something serious and able to win.... Just wait and seee  More news soon...............

Well coming from the rallycross side of things, all I can say is I'll have to take your word for it.
Just got myself a second hand ZX5 though, so who knows, might change my mind about Kyosho. Hopefully will

I really hope they're gonna produse this chassis soon. Hopefully it will be ready for the next outdoor season
But it's one thing that bothers me with this chassi. And that is the regular Kyosho axles in front, and the proline-axsles rear. Why can't they have proline-axles both front and rear?

To be honest I thought after after the worlds Kyosho might not bother with tenth and leave it for a while. I'm just glad they haven't

I think you mean Losi ? The losi front hex rounds out fairly easily when you use a one-way on a high grip track. HotBodies use the same offset as Losi but chose to use these larger hexes - meaning you can swap to Losi/Proline wheels quite easily by changing the hex / pin.
I've no idea if this new front zx5 stuff is the same off-set as the hotbodies / losi but if it is then it might be possible to put a Hotbodies / Tamiya 'losi size' hex on the front?? Anyone know?

Front end looks great ..... weight distribution looks very USA track style and thus may not be as good on the sort of surfaces we have in this country as the current chassis!!!!!!
One of the reasons I've looked at the Lazer chassis over and over again is that it is NOT a BJ4WE copy!

So Kyosho are going to mass produce what is essentially the KMC conversion - albeit with a cutout in the chassis to allow the rear diff to sit lower, and different front hubs?

Saddle pack layout should improve the balance no end, I just hope they decide to make the chassis from molded composite rather than carbon fibre. Just me I guess, but I really dont care for the cf plate style of chassis.

You never know, they might. Even though the 'article' says it's production (well, it wouldn't be red would it!) - I have my doubts. It looks 100% the same as the car from a the Japan Worlds but with the zx5sp front bits instead of the alloy parts.

Whilst I agree that the saddle pack layout is indeed the way forward this design, like the BJ4WE / Yok BX and their imitators, places the weight too far back in the wheel base to give the sort of balance we need in the UK. The Atomic Carbon S4 works so well because it gets the weight forwards which not only helps steering but also allows the rear to rotate controlably on higher grip surfaces.
Remember in the UK (and northern Europe it would seem) we race on much higher grip (both traction and side bite) than anywhere else in the world. That is also why we run different types of tire too..... Havinf said all that the trusted "ruler against the screen" method of assessing the layout shows the weight is slightly further forward than either of the two chassis mentioned above but still not as much as we can get away with in the UK. It does have to be remembered though that we are a comparatively small market segment compared with the USA and Asian markets!

By the way guys, stop saying things that are not correct regarding car handling, battery position and others.......
What's turn up to be a Handling thing becomes today a marketing thing......I mean that if a Lazer ZX5 comes out a day with this layout it's only because the MARKET ask for it.....What's happen nowaday with 4WD buggy it's exactly what happened to Touring car 5-6 years ago...... I bet with anyone who want to bet with me that i prepare 2 similar ZX5 but with a different layout "the old vs the new", run on a new track for one lap each time that he won't be able to tell me the difference....at all...This driver will come down from the restrum and he will only think and saying bullshit.... Only 2 drivers out of 10 can make a good difference today because they know and they drive every single day more than 4H per day.. If i bet it's only because we did it and even worst with Top drivers... Any car with any layout can go fast as long it's built for. Any car with any layout need to be setting as good as the others to suit the track condition and your driving style. The biggest difference that a layout can make......it's the difficulty in setting the car....a layout/car might need more time to get it well and it can change from an other to an other.....from a driver to a driver and more and more.....to many possiblities to fail as to many possibilities to be correct... The biggest thing in a car that can be feel by anyone and quickly it's a different transmission......Belt vs Shaft (This change a layout)...2WD vs 4WD (This change a layout)...Differential vs Spool/Oneway...and the speedddddddddddddddddd Anyway, even if i'm saying this, i'm still and stay a racer who always trying to have everything at the lowest CG, sometimes on the back, sometimes more up front......like any racer who love RC.....but sometime we need to stay lucid and just drive and perform well....Give the top driver a wheelbarrow and he will still beat you at the end of the day......and get his superb car you will always be behind........ Thanks

JonBoy, with all due respect (this post is meant with politeness and respect ... I hope that is how it is read), weight distribution is a key part in the physics of how a chassis handles. Geometry changes, especially roll centres, and sping / damper changes can all effect the way a car transitions from one part of the corner to the next and how it follows the ground. However if the centre of mass is particularly towards one axle or the other the natural characteristic of the chassis will tend towards under or oversteer. This is just pure statement of physics. I probably should tell you at this point that I am an automotive engineer who has specialised in chassis dynamics both in previous employment and during my years of study.
There will always be certain driving styles that will prefer specific handling characteristics in a car, model or full size. Part of the reason I find the Ultima RB5 such a nice car to drive quickly compared to say a B4 is it's balance, this is partly due to it's geometry but largely due to the car's weight distribution. Similarly the Lazer ZX5 I have driven is preferable to say a Losi XX4 for my driving style due to it's balance of front to rear lateral grip and it's sensitivity to small steering inputs. Both of these are largely due to it's weight distribution ... directly or indirectly due to the spring damper settings that can be successfully run due to the cars naturally neutral dynamic. Equally your statement about not being able to tell the difference between two different chassis layouts over a single lap is probably true, but mainly due to most people not being able to drive an unknown car at 100% on an unknown circuit. However I would put it to you that most people will be able to adapt to a particular chassis / setup combination better than others. The proof in if a car suits an individual driver is their ability to tune it too suit themselves well over the course of just a few runs. When I was racing Kyosho cars previously I always found their neutral natural balance easy to tune (to 95%) for myself and other people, the last 5% being a very personal thing. Some other cars have natural characteristics very much towards under or over steer and these are much more difficult to adapt to a driver if their preference is towards the other extreme. If this was not the case why are we all not finding one particular chassis supreme above all others, no matter the driver or surface! I understand that you have to support your products, both current and uncoming. I also understand that the UK / northern European market is small in the grand sheme of things and thus manufactures (certainly those outside this area) will produce cars that work well in the conditions found in the major market sectors, this would explain why Kyosho are researching the revised layout. I do hope that I have put my point across without causing any offence to you or the other readers of this thread as that was never my intention. All that said I was wondering if you could answer the question I asked you via PM please as your answer will help me make my mind up as to if I will be running a ZX5 SP for next season.

Yep, I think you are telling your grandmother how to suck eggs !!! We run a lazer, it suits us, but we would like to upgrade it a bit (we paid good money for this new & added aliminum & carbon fiber & pucker screws), we are looking to see whats in the Law35 bag and what it will cost us. but I am an old man and cannot wait on promices, them D4's look good and there is support, them B44's look good and I bet there will be lots of support, now tell me about marketing.

in regards to battery balance. i put the car on scales and each of the front and rear corner weights are within like 10grams of each other.
its pretty well balanced car with novak gtb on one side and EP4200 on the battery side.
