Hello @all!

Need Your help to find right parts. What items do I need (part-no. or link)to convert my stock zero-s to spool in the front and ball diff.-bak? And can anybody give me a tip what kind Servo-saver is a "good one" ?

Thanks
Bigmic

For a spool front you'll need the following, the pulley part may be hard to find though.

I use the Tamiya high torque servo savers, they work very well and will last you for a long time.

As for a ball diff, parts also may be hard to find for it. If you're going to get a ball diff, get ceramic balls as they will last a long time before you have to replace them.

Cheers
Rob.

Why not use a gear diff in the rear? Will be much easier to maintain and have plently of parts availability if you were to strip a few gears on the inside Just my opinion, sorry

+1

If you build the gear diffs correctly they don't leak and give you many race meets of consistent & reliable performance.
I have a ball diff in my F1 car and I don't look forward to the weekly cleaning & rebuilding routine on it, but if I want it to perform well it's something I have to do.

Anyway personal choice, the ball diff does make the car a little more forgiving but the gear diff will get the power down quicker.

Cheers
Rob.

Hey guys, I have a couple questions for you. I have the Zero that I put all the hop ups and carbon fiber on and it drove great on asphalt with a 13.5 motor in it. Now I am racing the same chassis as a VTA car on carpet with a 25.5 motor in it and I cannot get the rear end to hook up. The car isnt pushing at all so the front is great but when I try to turn, the rear end is just super loose, it spins the car out. Even on the long sweeper. Do any of you guys use this car as a VTA and does anybody have a set up sheet they would be willing to pass my way? Or just some tips and how you would set up the car.

The changes i'm going to make right away already are putting a lot heavier diff oil in the front, like 30k and leave the rear at 500. But other than that, I need u guy's help.

Thanks!
Kyle

I just ordered the zero s model, now im looking for spares. I see the front end parts are hard to come by!? Any others fit? (c hub, knuckle) Maybe I should cancel the order.

I'm at the Victoria wcics right now. Brought my XI to race and the Zero S as a backup. I collided with Brent W and busted my steering bellcrank linkage, which is all plastic.

Switched to my Zero to finish qualifying today. IMO, the box stock zero is more durable than the box stock xi.

Slightly faster times with the stock XI. But the durability of the Zero S (aka: Turning TG10) is a real benefit.

so i just bought this from hobbyking: http://hobbyking.com/hobbyking/store..._Car_KIT_.html

its suppose to be a Sakura Zero S clone i guess. i currently have a TT01 E and ive been having a lot of run running around with my friends. however i want to get more serious about racing and put a brushless motor on it and realized exactly why the TT01 is labeled as an entry level kit. it doesnt handle high speed very well, or at all actually. it just spins out. and from what i read its because its a shaft driven car and the motor is parallel with the chassis center line, so when you accelerate you get torque steer, and lifts one wheel off the ground and is very unconsistant.

so, i started looking for a good belt driven car to 'upgrade' to. and this car was so cheap, i couldnt resist. it was $93 shipped. im hoping it will perform better than the TT01, and if it does, i might start entering into the local races here.

my only question is, what pinion should i get for it? i have a 4400Kv motor

Anything from a FDR of 6.0-7.0 would be fine for you. In my Sakura Zero I ran a 80 and 26 most of the time (48p). This gave me good speed and low temperatures. If it's still too quick, go lower on the pinion to achieve a higher FDR to tame it down on the straights. Running that motor will give you alot of punch out of the corners with that FDR though.

Best of luck.
