Kyosho springs ...... we need to know!!
 

I have already had enough of not knowing what the rates of the Kyosho springs are ...................

What I am wondering is if people would be as kind as to lend me some springs so I can measure their rate on our specialist spring testers at work.

The idea is simple ..... people send me springs, I measure them and return them and produce a chart listing them compared to AE and Losi springs so we all know where we are.

Anybody up for helping me by sending some springs over PM me.

Springs
 

Hi Roger,

This would be really useful...

I've got a good handfull of springs that I can send over.

Just send me your address....

Cheers

spring ratings
 

Hi
i know a few of the spring ratings

Red #55
Yellow #60
Light yellow #65
Light green #75
Blue #68

those arent spring rates those are just numbers.

this is the magic spring chart and it has actual rates. it seems to be missing the stiffer then silver front springs.

oh well sorry i was told that they were the ratings

Mr X. That is the second time today that I have seen that chart .... thank you for posting it here!!!!

There are a couple of those ratings that I'd very much like to check out for myself as they are not quite in keeping with the "feel" of the springs. Hopefully we'll be able to fill in the gaps with my study!!

Jonathan, the numbers you give are the Kyosho identification numbers, not actual rates ...... all they really do is order the springs. They work as a guide to which spring in the Kyosho range to choose in relation to the one your currently using.

The chart Mr X has posted is in lb/inch rating so they can be compared with other manufactures springs.

Thanks MR-X this is really helpfull.

Now we only need a chart for the pistons :-)

Here is something (I didnt make it)
Piston conversions:
LOSI: AE: KYOSHO:

#54 = .055"
#55 = .052"----- #1 = .052"----- 2B = .051"
#56 = .0465"---- #2 = .0465"---- 2C = .047"
#57 = .043"----- #3 = .043" -----3A = .043"
#60 = .04"-----------------------3B = .039"

Just remember the "3" kyosho pistons have 3 holes not 2 ...... That means the damping effects will be different.

If I get some time I will do some calculations and post up the results .... but don't hold your breath!!

Its not easy to compare 2 and 3 hole pistons..... :(

Graham .... your right it's not easy .... the maths is quite a PITA to be honest but as soon as I get time I will try to do it for these nice people ;)

Tripped over this chart at today at rctech.

this will probs be silly obvious but wots fermer? rear losi yellow or rear losi orange?

Alex ... thanks for posting that up but it is incorrect!!! Now if you swap over the "grams" and lb/" columns then maybe ... possibly. I would still prefer to measure all the different springs on the same equipment however.....

The real numbers are likely to be in the region of 3.x for the fronts and 1.x / 2.x for the rears all in lb/"

I have started measuring through all the manufactures springs and so far I can say that AE and Losi do a pretty good job of making their springs as described.

The Yokomo spring set has some very useful rates in it when compared to the Losi / AE spring sets for use on Kyosho cars as the fronts are a similar length to Kyosho springs (cutting the losi springs down to a similar length results in VERY high rates ..... put it this way a Losi Orange, cut down and reshaped to 45 mm goes from 2.8 to 3.5 lb/" approx)

I am struggling to get hold of Academy and most importantly Kyosho spring sets to measure.

Once I have some Kyosho springs measured I will post up my findings.

The problem with using Losi springs on Kyosho cars is the free lengths are so different. The Losi front springs are too long (about 5mm) which means that getting the front ride height low enough is a problem ...... the opposite is true of the rear (about 6.5mm too short).

To get around this in the short term I am using the plastic non threaded upper platforms and Losi lower platforms on the front (with clip in spacers I have in my box from something) and 5mm spacers made by trimming old Losi screw fasterned (non threaded) upper platforms between the spring and the threaded upper seat. Both look rubbish and make adjustment a faf.

I will be turn up some proper spacers to use Losi springs on the rear as with my own chassis design on the ZX5 with the SP rear arms you can't get the rear low enough (the center of mass is further forward .... significantly).


Billthemina I'm sure your not the only person who will ask that ..... The yellow is softer than the orange .... the lower the rate number the softer teh spring.

thanks :D

RogerM ... I agree with you that the columns are wrongly titled (grams should be lbs). I overlooked that due to the experience I have with Losi and Asso springs. If you use the columns as it should be the data "feels" correct when trying the springs. Of course it is not as precise as measuring.

As for the Losi rear I have solved the issue by using 2 Kyosho preload adjusters on top of each other and the Cyclone D4 lower platforms - fit from the diameter but are higher tha the Losi ones. No porblems so far and looks great.

Changing the front springs really is an issue. But so far I am quite comfortable with the Kyosho front selection from orange to yellow. I tried Asso fronts with an additional plastic spacer but I didn't like the looks and feeling of the springs on the Kyosho.

In any case I would appreciate tested results on the springs ;-)

Best Chrismas wishes

thanks for the info..

I'm new into the RB5, bought one second hand.
I 'm planning on buying some spares just in case and add maybe some tuning-material.
Actually I have the lime yellow/greenish springs in the front and blue-purple on the rear.
Could someone tell me what springs I might need in my spare box?
Or are the ones that I have pretty common.

I've looked through some setup-sheets and encountered these allready
front: Silver (70), orange (?), lime yellow(75), lime green (?)..
rear: Blue (68), mauve (72?) , silver (?), ...

Which of these should I buy?

You can have a look here for off-road springs. There is also a chart in attachment some message upward.

Sorry guys, just a quick one, are some of you running Losi springs on the FS and if so, what are you having to do to get them on there, i have all the losi spring selection so if i can run them i'd rather use them until i start replacing, also do losi pistons work in the shocks at all?

Just run the losi bottom spring cups thats all you need to do to run losi springs, although on the front the greens and the blues are too long. No the pistons do not fit.

Hey Simon, thanks for the super quick response

Is it possible to but the Associated spring set (with all the different rates) and use them on the Kyosho shocks? I reckon I need to change the spring cups aswell, but what about the length of the springs?

It's to bad Kyosho don't make a spring set for the RB5 and the ZX-5.

guys, hopefully someone can help...

I've got a few sets of kyosho springs, but it just seems that different people have differing opinions on the actual colour codes of the springs available.

Fronts, i've got what looks like orange, a lighter orange, yellow, silver and lime green

Rears - i've got green, lime green, yellow, blue (think they're the cobalt ones), lighter orange, silver, black

I'd be really grateful if someone could put them into order of stiffness, and/or tell me what each colour above actually attributes to in terms of what colour it's classed as. (Also, if i'm missing any worthwhile getting)

Cheers all,

Stanners

Did you read the whole post?

I'm sure you'll find your answers here:

Weight is how stiff they are, but Kyosho have different numeric settings for this. Ranging from about 45-80 or so...

I do believe that if you look in your manual, you'll find the colors and stiffness under "option parts available".

Hope this helps!

Did you read my post? I said i had spring colours that don't attribute to what's on the list

Cheers for the effort though

Here's a more complete chart:

As for the blue vs cobalt

Blue are a navy blue and you can't miss it. cobalt are more of a purple than a blue shade.
