Here's some action from veecee and my final last night. I'm the white car that's in second when the vid starts and veecee is the green one on the right that gets nailed at the very beginning

that would be logical, though... isn't orion now owned by kyosho? wonder if that would pose a conflict of interest?

Hey Ed,
So what are the popular HPI springs that seem to work? I wanted to order a bunch to test.
I now have access to an Instron Test machine again, and I can find out the true in/lb rating, as well as plotting out the force/distance profile to see if they are truly progressive.
We can update your spring chart with more good data.

Ling-I have the full set of HPI Pro4 springs that you can borrow if you want to test them. Let me know and i'll bring them with me sat.

The set up looks like it would understeer, compared to my old set up with the same springs the front suspension is stiffer, the front roll centre higher, but then you've countered it with the lowered front hubs, less rear toe, more upright rear shocks, and medium rear sway bar, so less grip all around and pretty stiff... I'll def print this out for our state titles which are on a big grippy track
The kick up is for the bumpy track, but also because the track I race on requires quite a bit of mid-corner. Previous to the weekend I had been running it by using 0.5mm spacer under the front block. However, I wanted to lower the front roll centre a bit for more front end, but keep the camber change the same (i'll come back to this in a tick)... so removed 0.5mm from underneath the rear block (so now only have 2.5mm under the block, rather than the kit 3mm), whilst putting the front block on the deck. Did exactly as I expected, and made for a much more positive front end, whilst still retaining the good bump absorbtion, and mid corner steering.
I did note that in one corner in particularly the rear end was breaking loose a bit quick now though, so I'll counter that by going back down to 1XA/1E on the rear end.
BTW, 1X/1F is still 3 toe in, i was just itching to try out the 1F block to see what the change was

The track I'm on is pretty tight, but also has decent grip too... so going stiffer has two positive benifits, keeping corner speed up, and improving reaction of the car. I'll agree that the way I have it setup at the moment, it's pretty stiff... but it certainly seems to be working The 416 naturally has a lot of rear end grip, so you have two options really, give more to the front (probably better for lower grip tracks), or take some from the rear (better for the higher grip)... guess which way I've gone

As for the front roll centre, yes it is higher... however this is countered by the increased angle of the link, which gives a lot more camber change during the suspension movement... so in effect, you get a response benifit from the high roll centre (nice), whilst also retaining a good level of grip from the front tyres during roll thanks to the camber change (again nice ).

If you get a chance to try it out, please let me know, I'd be interested to hear others thoughts

Regards
Ed

Hey Ling,

The HPI Springs blue (HP6542), silver (HP6543), pink (HP6548) and gold (HP6544) would be good, as they seem to be the most used HPI Springs. The AH ones mentioned would be good as well, certainly

Be nice to finish up the chart, certainly the progressive data would be interesting to know

Cheers
Ed

lol yeah I realised that after I'd shut my computer down last night, what's the difference in track width between 1XA/1E and 1X/1F? Essentially that set up has lengthened the camber links even further and taken the rear track out too, I would think that would all conspire into understeer but maybe the front end changes have countered that, in which case I definitely need to try lowering the hubs - I was going to do this the other night but the car was too nice

A question about wheelbase, I've played around with the rear a bit and found as you've said previously that affects the rear end rotation through the corner, but what does the changing the front do?

I was just looking at pulling together a few of the setups from big events, but i cant see anything from the worlds warm ups a few months ago in Thailand.

Anyone know a location?

As for the HPI springs, thats interesting, cause I tried Silver/blue this weekend and found the car to be binding up mid corner as it was rolling over too much. I went back to the tamiya White/blue and it was fine.

Having said that, the track I race on is pretty high grip. I'm going to try HPI pinks and silvers next time out, and see how that goes. I don't doubt the silver/blues works on a lower grip track though, and the car did seem to roll more progressively than with the tamiya springs (so agree with you there), just too much for my track

Anyway, have a look at my latest setup from the weekend, I've done some interesting things on there now... and was on for a PB at the track in the last final, even though the rear end was a little loose I think with the HPI's and a little more rear end grip, I could be on for a 21 lapper (the holy grail for prostock at our track )

Ed
Hi Ed
A question about your setting~~~
In the sheet, there is a statement about front hub:
"Front hub lowered 0.5mm by flipping the lower collar"
Is that means we need to make the lower king pin collar inside out, and to have a 0.5mm spacer above the wheel knoble together with the original 0.7mm spacer?
What is it use for? to low down the rolling center or other concerned?
Thanks!!!

Hi,

next Month there is also the possibility for new Damper Retainers, which will fit perfectly to the HB Springs. This will also be interesting for the 501X.

I think also the WE will be a fully hopped edition with all the features, which will be used in Thailand in November (1C-1C and 1XA - 1F), Spool inside, One Piece Topdeck (like RCm said), a aluminum steering brace, which can be spacered to the regular one, and last but not least the new blue titanium Turnbuckles. About the price: I guess it will be 79.800 Yen. Pics will be available from mid October.

Brad: I haven't seen any of the pro's set ups for ages, the latest ones were from the reedy race. I was really hoping to see some from either the andernach round of ETS or the Euros, though they don't look to be doing anything special from the pictures.

Jontang: you are right, you flip the collar and add a spacer under the top one. Not sure what it does from a technical perspective but the result is more steering

Dai: The new retainers sound cool! let us know when they are available

I'm hoping that they will finally come out with aluminum rear uprights!

The square ones are sweet, as are the steering knuckles
