Hey guys, this is my Sakura Zero, i have been drifting for about 3-4months. Ive been CS drifting at 34% for about a week and 68% for about a week and a half. I'm open to constructive criticism and would love to hear some feed-back on my car/setup. I have only been RCing for about 5months now and im loving CS drifting, its a challenge to start with but i can now handle my car pretty well. :)

EDIT: upped the cs from 68% to 72% (not much i know, but, hey...)

oh, just a quick mention cos i know someone is going to say it.

i know that having the tensioner on the teeth side of the belt wears it out quicker, but I am yet to find an alternative with the 32T rear pulley. When i find an alternative i will post it up. :)

my first rear belt was destroyed because of that. You can have a tensioner like that on the toothed side of the belt but only on the front belt because there there's no tension above the pulleys when you're going forward, like usual.Of course, that's when using the tensioner on the topdeck. On the rear belt, the tension is above the pulleys. A tensioner like those will crush the teeth. You can:

-Look for a smaller belt ;
-Make a tensioner that tensions the belt below the pulleys;
-Use a pulley on the tensioner.

The last one it's the easier, I'm using that for several months. Nothing to complain

By the way, I think yours it's the first Sakura Zero I see as a drifter :)

Can you tell me 2 things? what gear diff it's that? Spec-r?

Can you measure if your shocks are 50mm or 55mm? I need 55mm shocks for my Cyclone and those black and pink shocks are a blast

For your rear belt tensioner, just want to show how I did :
Image

Image

Image

Servo mount + screws + small pulley (17T for mine) + bearing inside the pulley. ;)

I ran 1 weekend drift sesh with a rear belt tensioner like yours cuz not the time to did this one but the belt is fine.


Otherwise, nice modded chassis :)

Well, I've been drifting with my sakura for quite some time now with an OD ratio of 1:1.83

Here's what I did with my tensioner:

Image

Image


Got it from a Local Hobby Shop here in Dubai.

The rear belt is from Tamiya's TA-04.
Keeping a rear belt from Xpress (4WD M-chassis) for when I get a 27 or 28T rear pulley and it will surely fit without the need for any tensioner.
The Xpress belt is just too tight for the 30/22 rear combination.

hey guys. thanks for the input. :)

I haven't had much time to try things out with the tensioner, been busy buying a 1:1 car and getting married, i'll have a play when i get time and I'll let you know how it goes. :)

The shell is the official HPI one.

In the local drift scene i frequent, the Sakura Zero doesn't exist, 99% of the guys there hadn't even heard of it until i came along. Mine is an up-spec'ed Zero "S", one of the first out of rcmart, for the price(about $100 +hop-ups) the chassis has been fantastic. The gear diff is the stock one, i have heard of people using other branded gear diffs but don't quote me on that.

All that has been changed from stock is;

CF Chassis + CF top deck
Solid rear axle
Pulleys
Custom steering mod
Alum motor mount (vertical MKII)
Alum bulkhead covers
Shock springs + Oil
Sway bars
Tensioner

love the pink bling, lance. :) will get the bulkheads at some stage.

Unsane_chimera, could you please specify which parts you have used to achieve that CS rate?
What I´m interested in is the manufacturer of the following:

Front: 39T
Center: 16/22T
Rear: 32T

Since 3Racing doesn´t offer these parts for the Sakura at the moment it would be a lot easier if you could inform of what to buy, rather than to have to buy and try out a lot of different brands :?

Hope you´d like to share your knowledge :up:

The front pulley is from 3racing and so is the 22center pulley. The 16center is a tamiya from the Ta05 and the rear 32 is from Xpress. All from RcMart. :)

Cooper, the shocks are 50mm from the center of each ball joint when at full extension.

Sakura gear differentials are available from 3Racing. It comes with 37&39 pulley attachments. But you can get a 39&40T pulley replacements for them too.

Square 40T Ball Diff pulleys would fit too.

32T pulleys are from Tamiya TA-04's
You can get a 30T pulley from Square as well for the rear.

Some may have to be moded to fit. But this is what makes this hobby very interesting - being able to tweak your car to your preference.
