Hi everyone.
My TT-02 won't drive straight after a left curve. So I'm trying to solve this by removing any slop or play + making sure that every piece of the steering moves freely.
First I noticed my Hitech 5646WP servo was unable to zero reposition after going to the maximum left or right... Not sure if it's due to the servo, cause I checked the whole steering system and nothing seems to cause much friction or oppose force to the servo..! Any idea? Any good servo to recommand? (I took this Hitech because it's waterproof, and I rally sometimes)
Second I notice some play (~1mm) between the Hop-Up Low Friction Suspension Ball and the front upper arm they are clipped in!!! Does anybody have the same? How do I reduce it? I have the kit upper arms, should I change them? Does it make sens to put camber to the front wheels?
Plus I'd like to shim the differentials, what shims do I need?
Thank you in advance.

You can tell also if you test the servo by itself with no load, making sure you have a marker to see if it's returning straight. I've used $20< servos and they were never the issue of the car not centering properly.
Assuming you have no binding anywhere I would put a bet on the servo arm being loose etc.

Is it not returning to centre with load or no load? When I say load I mean the car rested on the ground - if it's a tad off that may be expected due to the nature of the car. It should return if the car is raised with no load.

Here is a mod to add front camber, Caster and also change the roll center
The TT02 is running superbly at my local club

Hey guys,
Just picked up the Type S today. This is my first foray into on-road
Bought it as a Xmas gift for my 8-year-old. Picked up the alum center shaft, heat sink and Yeah Racing adjustable motor mount as hop ups. Looking forward to enjoying the build. Cheers,

You will definitely benefit from buying aluminum steering uprights. It's a weakness of that chassis and the other cars in the TT's series.

I'm trying to keep the hop-ups as few as possible
Cheers,

A little hard to put together (instructions in another language) and you'd probably have to buy the full kit in order to get replacements, but does the drifting job well.
It's pretty similar to the newly released type s.
I'm selling mine on eBay if your in Aus.
Cheers,
Crouch

Cheers,You will not need these on the TT02S as it has the TRF 416 uprights. These are fine and you will not need to upgrade anything on it to start out with.

Cheers,Key hopups id say are
-bearings
-aftermarket servo saver e.g. medium kimbrough - to fix up the poor steering of the stock tt02
-adjustable steering setup, tie rods etc if you want to change toe settings
- oil shocks
- maybe a couple of different pinions to fine tune gearing if required
The stock servo arm I'd say is possibly one the biggest flaws with the TT02.

Hey guys, finished building the kit. Overall it's nice and there's no rocket science behind it. Some initial thoughts:
1. The turnbuckles into ball cups are super tight. Even with black grease it's quite a workout wrenching them in.
2. I'm not quite sure with holding the hub hinge pins with a grub screw only. The pins are not keyed in or secured at the ends. At worse could do with some e-clips at both ends?
3. Speaking of e-clips, I'll never be able to remove them off the shock shafts to change the pistons..
4. The shocks could use some green slime to seal the tops.
I followed Oatmix's blog, but up to a point as the Type-S version is much different. The front c-hubs and rear hubs are improved as well as more tuning options. The original had no turnbuckles?!
Now to prep the body and give it a run. I would say overall it's a nice and easy kit. One does get a sense of underwhelming though. It's slightly better than a re-re IMHO! But as an entry level kit it's great. Personally I would not put anymore hop-ups into it, and put the budget into a higher level chassis. Cheers,

The TT-02 is an entry level kit and I think it's not bad for its cost. Question is - how much can you ask for say a $100 kit. What are your goals for this kit? Are you expecting to compete in say stock class? If it's underwhelming, are you being reasonable comparing it to higher kits that are 2/3x more costly..?
I think with a good driver the tt02 is capable with even the basic of mods/right tyres/select battery on a track.
