Sosidge. greetings from Malta.

Certainly my experiences - an average of 4 packs a day for a whole week, show that on a fairly grippy tarmac surface the standard springs with 40 oil seem to work OK.

I set the top arms so that i have virtually no camber change and i have inclined the shocks more. Now I need to fine tune with droop settings.

Like yours mine has a tendency to understeer on power. I improved it with the 7 degree front blocks and I think I will improve it, as well as the oversteer when braking into corners caused by weight transfer but reducing the droop.

But it's getting better each day. Tomorrow I will take my old faithful BD car too and run them both, just to compare lap and race times.

Yes Ralf. I am alot happier now. Good luck Sunday.

GILLES. (Utieh). I have received the blocks. Do you want 5 degree or 7 degree. I have both.

Regards

Joe from sunny Malta.

You can find White Lightening here:

Just installed the one-way and swapped out the kit screws for a set of TakeOff titaniums.

RANDMAN.

These are for the MR4 belt drive car but they are a direct fit on the SD.

I use them on mine.

They are Team Suzuki sold in Europe as Fastrax number FTMR04.

I just found that one of the pins in a rear CVD had slid out half way, so I HOPE that was part of the cars problem... if not, more work!

If there is any question on the freeness of the driveline )and I don't think there is) don't worry. With nothing but proper shimming of the driveline and cleaning the bearings out, I have gotten a consistent 13-14 sec of spin. And thats a light spin. I even kept the rubber sealed diff bearings.....I can honestly say that this car lurches forward noticebly faster than my FT TC3 ever did. And I had hours and hours of work on the FT. Awesome job Yoke!!!

Hi guys. Greetings from Malta.

THE GAME>

The Yoke SD is the freest car I have ever built. I'm impressed.

I build at least one car a week. It's my job, and I have built virtually every type in existance, Yokes, Schumis, TC3, Losi, Corally, HPI, Tamiya, you name it. My son runs the quickest TC3 in the country which I built and maintain for him. The bearings got the works and they have run for a full season now, but it's not a touch on my new SD in terms of free running.

I built the SD to kit instructions in so far as shimming is concerned, and I never bothered fiddling with bearing seals etc. It needed a few minutes running to loosen up but now that i have done some 20 packs - 100 minutes, it is the freest car i have ever handled.

So if yours is initially a bit tight, just put it on the track and run it - and run it - and run it.

Regards

Joe from sunny Malta.

Indoors, slippy floor, Shumacher narrow yellow minispike tyres, so most of the setup will be meaningless to a lot of people.

In fact, the car ran best with the stock settings, except for no anti-roll bars - 40wt oil, ride height 5mm front, 5.5mm rear, with droop of 2mm at the front (measured at the chassis), and 3mm at the rear, 2 degrees camber all round for even wear.

Everything else I tried so far has been worse - I was aiming to improve consistency on the limit.

I've softened the car up and increased droop for my next run, I'll be trying...

Front: Yellow springs, 40wt oil, 5mm ride height, 3mm droop
Rear: White springs, 30wt oil, 5.5mm ride height, 4mm droop

I've also removed the foam circles from the shock bladders, I felt they gave too much rebound, which is apparently not the thing you want when grip is low.

Lots of things to mess around with though, including less static camber, more rear camber change (raising the outer balljoint by 2mm), different droop settings, rear shocks in one hole on the wishbone etc etc etc...
