Worlds Warm up Tebo's Car

[carlin]

Hi Guys,

Seen this on another forum don't think any of us have seen this on any pics

Here it is see what you think

[reg]

its got some mega droop

[ZenMoto]

It looks to me like there are gradient markers and a pivot. ...I'd guess you mount the shock lower to it and it allows you to make very fine adjustments to the location of the lower shock ball for fine tuning the handling.

...pretty cool if that's what it is; but it's really hard to tell with such a grainy photo.

Is Mr Tebo telling us Kyosho put the holes in the wrong place?

[njc11]

Looks like they are back on the shorter drive shaft, longer axle aswell..

[RogerM]

Nope .. Kyosho definitely put the wishbone hole in the right place for the car with current geometry.

I was hoping that people might not stumble across this (and a few other) things that are being worked on.

We'll say all will become clear soon enough and also if you have money on anybody else but Tebo for the 4wd title I'd best see if you can move your bet

Aaah, do tell more !!!

New car? upgrade parts?

@ Carlin, which site you found pic ?

No one knows anything to tell you. Kyosho like other Teams ALWAYS work hard before a world championship and new parts are ALWAYS seen at the Worlds. Roger or anyone else in fact does not know anything about any parts upgrades apart from the direct Kyosho Team drivers that test any new items. Tebo has been testing for some time now.

Drilling another hole (if that is what it looks like - LOL) is not rocket science. Ellis did that some months back on his FS2 as did Alex Carter before that and so on. I run the FS2 on that possition often.

Like I said there is no question new parts will be available for all the Kyosho drivers at the Worlds and that is why Neil Skull posted a thread requesting the names of everyone attending......

Anyways, it won't be long now and all will be revealed ......

Looking at that pic again... if you look closley the the pick up point for the bottom of the shocks has been lowered to below the wishbone.. looks the same mounting positions just lowered..

Should help with more up travel on the shock after the chassis bottoms out?? Something it lacks at the moment.. i wonder if they wil do anything at the front...

[RudeTony]

Nick - It looks like they picked up on the original outer hole and then 2 additional inside holes thsat are lower - the reason it's lower must be to keep the same droop

[njc11]

Have a closer look matey...



It defo looks like same position but lower down.. more up travel etc and better adjusment for ride height with stiffer springs..

They are going for the Gull-wing effect ie: Lower C of G with those big bores, surely ?

Okay, id move my bet to one of the following... Lee martin, Neil Cragg or Ryan Maifield!

I saw on Petit RC that you did that on one of your latest setups. What it is supposed to do to the car?

unless they're shortening the tower the COG will stay the same, if i'm not mistaken. hopefully that is the concept though.

big changes going on before the worlds, good stuff.

When you run the car narrower by using the different inserts in LAW36 and LAW37 (im using AA front EE (out) back) the drive shaft is getting marks on it when using the full up travel of the suspension.. so snagging as you would drive it because its plungeing to far into the diff outdrive.. Since ive had it with shorter 62.5 shaft and longer axle etc its not marking the drive shaft anymore.. and the car seems more stable through the bumpy bits..

Im at Southport again this coming weekend.. trying some different pistons ive drilled out... 5x1.4 front and 5x1.5 rear..

[RogerM]

The reason for doing the driveshaft mod is reduced driveshaft plunge ... in the normal working zone there is MUCH less plunge with this set up.

Under power there is load between the dogbone drive pin and the out drive, this load combined with the frictional terms between the pin and out drive conspire to bind/hold the drive pin in one position, resisting the plunge needed to make the suspension move freely.
This in turn resists the suspension movement making it a little harder for the suspensopn to cope over really bumpy surfaces, the drive shaft mod helps here as the less plunge require = less rsistance.

So why didn't they just do that in the first place I hear you ask? Well the position of the outer drive joint, or more specifically the arc the center of that joint makes as the suspension moves through it's travel, also plays a part in the way the driveline works and influences the suspension as a whole. Luckily there isn't too much of a problem here with the new setup as the arc traced by the joint isn't fighting the arc swept by the suspension. With most cars it would be enough to limit the squat effects making it harder for the car to squat to a position below driveshafts level but as the FS doesn't migrate it's center of mass rearward under acceleration to create much squat it's effects are hardly noticable.

I ran the mod on a fairly bumpy track at the weekend and it definitely made the car feel a little more fluid when accelerating through the rough stuff, I can't remember my car being kicked about on some of the worst bumps that the B44s & Dingos seemed to be finding. I would however expect to be taking it off if I went to a smooth but low grip track (say indoors on slippery floor) when I was running the car below driveshafts level as a typical ride height and wanting the maximum traction out of the slippy stuff.

As an added bonus as Nick states it also allows you to run a bit more up travel without a clash between dog bone and outdrive too, another bonus.


As far as the "gull wing" mounts they are a means to an end I believe. By using those it allows them to run almost any lower shock mounting postion combination along and above/below the wishbone. This will allow them to trial almost infinite changes without having to make new wishbones each time, simply a logical engineering solution for prototyping! I would expect it to give rise to some new wishbones, not the moutns coming to the market.
With Kyosho's standard way of supplying wishbones (which they have been doing for as long as I can remember) it would make no sense for them to have none-symetrical parts like bent wishbones a-la B4 etc. Who knows that may change though.

like how they modded the rearfor lipo's made hole in the carbon to connect to the batts.

I also see @ the bottom on table using carbon braces to hold the lipos in place.

Looks loads better, we will have to wait & see what else pops up
