Hey Zero S Racers. Having some minor rear end issues and have tried the following so far..

For 17.5 blinky on Small tight track

Front:

Hexes = 6mm
I still only have the normal length arms
one step softer than stock springs - 40wt oil
Stock shocks and pistons
Shock outside hole top and 1.4 sway bar
.5 toe out, 1 degree camber 4 Degree caster blocks
Diff - 300,000 wt
alum upper camber link mount in the middle front hole with 2mm of washers under ball stud
a-arm mounts no shims
Ride height 5.5mm Droop +4mm

Rear:
4mm hexes
I still only have the normal length arms
2 steps softer than stock) - 37.5 wt oil
shocks in one hole on top with 1.5 Sway bar
Rear 3 degree toe in 2 degrees camber
Diff - 80wt
alum upper camber link mount in the most inside hole with 4mm of washers under ball stud
a-arm mounts no shims
Ride height 5mm Droop +2mm


Much Moore 32 Tires Full rear 3/4 front compound


The reason I went lighter in springs is our track is low on traction. the carpet stays layed out but only gets run once a week and it's old carpet

What I need is the car to be better when going thru a chicane where it's immediate right to left to right steering. the car gets out of shape in the rear really easily. and on power it pushes just a little but too much.

41 or 42/100 64p pinion/spur with the 19t/38t pullies should get you where you want to be.

And, yes, you'll really need to stretch out the belts if you use the 21t pullies as they belts are too tight with the 20t pullies -- which is why everyone runs the 19t pullies

I just want to clarify something.

I am wanting to do the rear shock tower mod and want to get a thumbs up before I purchase the items.

I am going to need the sakura zero S FRONT bulkhead covers....

http://www.hotshothobby.com/Front-Bu...-SAK-34-PK.htm

And this shock tower for the 416

http://www.ebay.com/itm/130436359610...84.m1423.l2649

Is this all I need?

X1 tower fits with no mods, i believe the tamiya one needs the holes drilled out a little

Jdeadman try reducing rear droop to 4 and softer swaybars 1.3 f/r add more front camber and lean front shocks over one hole, front ride height should be lower than rear, keep your roll centre similar f/r so go back to standard 3mm allround and tune by 0.5mm good luck

Hi All

I gave up racing around 9 years ago when i raced a mission and AE TC3 things have moved on a bit

I am looking to start back up again and have been looking at the S model as its the only one available in the UK at the moment and the price is amazing

I don't want to spend 360 on a new car

Choices are a second hand 2011 X-Ray or a Sakura S.

I really like the idea of going against the grain as I know most members of the indoor clubs i will be attending are running X-rays

I'm rather worried about getting a good carpet setup

By the sounds of things I will be wanting to go in the 17t blinky class

Whats the first hot-ups and whats the setup advice for a neebie

To add to this I am moving from a stick controller to a Wheel

Hope you can help

The car is fine box stock, but the belts are a bit on the tight side. Most have purchased the 19T layshaft pulleys along with the pink alloy spur gear adapters.

The stock motor mount is a PITA and access to the rear motor bolt is through the spur gear. I went with the vertical motor mount to eliminate the bolt access issue, but this move involves mods to the upper deck and you also need to flip the belts to the opposite side of the chassis. When you do this the belts rub the battery tray guides and these need to me modified or removed. I posted pics of my mods and you can do a search for those.

I also opted for 64P gears as this allows for finer tuning the FDR. Personal preference really.

Hi,

I got a Sakura Zero S with no hop-ups other than pinions/spurs to adjust the gearing. I'm running it in 17.5T as well, also as a newb.

If I got only one hop-up, it would be better turnbuckles than the kit has. The kit turnbuckles have rounded flats and don't work at all.

The motor mount would be nice, but truthfully, once I got my gearing set, I haven't needed to fiddle with the motor screws at all.

I am using the stock 20t pulleys, and although the belts were tight when I first built the car, they loosened up quickly.

The kit screws strip their heads easily. I would invest in a high quality 2mm hex driver before attempting the build. You may also want to pre-thread the holes with a motor screw (3mm screw, 2.5mm head for more torque) or a tap, and use oil or grease on each screw during assembly.

As for setup: I don't have any recommendations other than spending more time driving than tweaking your setup. If you accurately implement the setup in the manual, the car will handle well enough on carpet for you to spend most of your time improving your driving skills.

I hope this helps,
Alan

Oh yeah!

I also meant to ask: does anyone know where to get more Zero S kits in the US these days? TQRC and Integy are both out of stock. I really hope they don't stop making them.

Thanks,
Alan

If you don't see what you are looking for on the site, call. Sometimes they have parts in stock that aren't on the site.

Thanks guys

looking at the hop ups that I would consider while building the kit I might go for a XI DH version not sure if it will be more cost affective in the long run.

But either kit looks great value for money

The xi is an awesome car. you may save a few bucks upgrading a zero s but not much. Either way you will have a great car. I run an xi and my son has a fully upgraded zero s with the narrow chassis. We have no problems keeping up with other chassis.
