Sworkz S104 Evo Thread

[Chris Elworthy]

Are people having the car run in reverse when diffs are installed as per the manual? I and a few others have had this issue. The manual will need updating if it's wrong?

its not wrong. It just not been updated to allow for shorty config.
When changing between shorty and saddle you need to flip the diffs. Dont run motor in reverse

[Chris Elworthy]

Cheers for that Steve.

Just got back from my S104 Evo's maiden voyage and what a machine this car really is!! TQ'd and won all 3 A-Mains the car was superb!

Following Steve's advice I ran Kyosho shock shafts and O-rings which made the shock package much more consistent and predictable. Following the 4wd locals as I haven't raced a 4wd car before I went for Yellow LP cut staggers on the front but had problems getting the front of the car above 18mm ride height when using AE Springs. I managed to cure this problem by taking off the shock collar and fitting upside down, this gave me the extra 3-4mm I was looking for. It's not an ideal case but it does work and only will be an issue if running Low Profile tyres on the front.
Car felt a little docile on power to begin with but after round 2 of qualifying it hit me that the servo saver wasn't tightened down all the way making the steering a little soft. When tightened the car became a whole different animal and felt far more direct and quick.

This car is just so easy to drive fast! I've never driven a car that just doesn't want to grip roll however much you abuse the throttle and just inspires confidence it really is excellent!

My car is built stock in terms of roll centres and hinge pin positions front and rear.
I have the front shocks on the middle hole tower/outer wishbone and second inner on tower and inner on arm on the rear.

600cst oil in the front shocks with AE purple spring
400cst oil in rear with AE green spring.

20mm ride height

Diffs: 15k front/1million centre/7k rear

Awesome. Try thicker front and rear diffs it's even better

Wahey we love a good video

[Chris Elworthy]

Get the vid up mate!! Hope it's one of the finals when the car was really good! Ha!

[Chris Elworthy]

Bury tend to have plenty of tight technical corners so a car that rotates quickly tends to be quicker hence the diff oil choices but will give it a go.

A pointy car tends to be a quick car round there

I'm running 20 and 15 in mine. Still feels lighter than 10 does in most other cars

[s22jgs]

Where's this video lol

[Chris Elworthy]

He couldn't post here so sent me the link privately.

If you go on YouTube and enter Paul's username StickyGeko you will find the vids.
One vid is from early on when the ride height on the front was far too low so was slapping bumps, . The other is from later in the day when the car was getting dialled in and shows a clean run.. This one should appear first

Another night with the S104 last night.
Limited the experimentation last night and just tried to spend some more time with the car.

I did go a further 2mm longer on the wheelbase though which was a vast improvement. Now running at 280mm

Got 1st round TQ, but Mr Rand stole it away from me in Q2 leaving me A2, where i also finished.

I did find though that the Kyosho shaft/oring shock mod, while it feel great, leaks air and i was gaining upto 50% rebound per run on the front shocks. Didnt seem to affect the lap times too much, but it did mean the cars feel changed throughout the run.

Will now be experimenting with AE x-rings and the RDRP white orings.

I would however definately recommend taking 3mm off the rear arms as the extra wheelbase really helps stabalise the car on fast sweeping and on power corners.

Why one should use different cars shock shafts and xrings/orings?
Is something wrong with kit ones?

all info is in this thread

[Stickygeko]

Hopefully picking a kit up later today, wont be able to build until thursday though.
I am slightly worried about shafts, I can use AE orings if need be. But id like to try the kit shafts or should i straight away go for different ones???

Im really tempted to buck the trend and build it in saddle formation too (purely because we have 6 saddle packs and zero shorties)

Nothing to be worries about. just remove the oring spacer, and dont fully tighten the bottom cap for now.

I am going to try a few other options this week.

Once i am completely happy i will repost my solution. Sworkz are looking into the binding though so they will be releasing a proper fix

I`m building mines with the stock parts, as I havent now aviliable AE orings or shafts, neither Kyosho, but car must be ready for Sunday when it will be first practice day for upcoming indoor season.
So will build mines with the parts which come at the box, only AE springs I hope to receive on Friday...
Later will give feedback how EVO performed at our track

[Stickygeko]

Really pleased to say we picked the last kit Answer RC had in, seems they've flown out. looking forward to the build but due to work I can't start till tomorrow night

[s22jgs]

2 small changes last night. 2mm extra on the wheelbase, and also the use of active caster. Im a little undecided on the caster, but it certainly made the car easy to drive.
