遲來新手, TT01 spin spin spin ....

Used to play R/C as 放狗 for years.. never serious to play in track before.
Recently start playing with my friend in TSW/JV with my TT01 years before..

All has been good when I just keep using stock motor. Until we finally upgraded to BL motor/esc and buy some new tyres.. things start getting out of control.

Last night test again at JV and both of our car could hardly turn. It just keep spinning

The spec is
TT01
Aluminum Shaft
S9451
HW 60A BL 19T/61T
Sorex 36R

I tried to read some posts and here are some query:
1) "smoothen' the A arm will help? (I read some post said this may be the cause?)
2) adding 'front solid diff' will help?
3) the tyre we bought, can use immediately on track? or need to do some procedure like '搽呔水' ?

Thanks all !

Use front solid shaft replace the diff will be get more stable at steering.

Hi there, smoothen the A-arms will help, also the tires should be good to go out of the package, sometimes needs to run in the tires first (run the car slowly for about 10-15mins).

Thanks guys.
I will try to get these
1) front solid diff
2) universial joint
3) spacer
4) TRF suspension
and install one by one to spot the difference...

hope could 'turn' on the track next time

Don't waste your time & money, just change the tt-01 to any "平板"車...!  Like a SAKURA S etc....

Just some experience sharing. I am having fun to improve my TT01.

My TT01's speed improved a lot when I use a Kadawa 48P 66T spur gear, 25T motor gear, alum shaft and 8.5T motor.

For how to use Kadawa 48P 66T spur gear on TT01. I learn from this post.
http://bbs.rc-evo.com/forum.php? ... &highlight=tt01
I use a TB03 spur gear adapter. The center shaft of the adapter needs to be cut shorter.

After several tests at JV, the car is unstable when going straigth. The next change is rear toe in 2 deg by using 2 deg C-hub. Problem solved.

It provides similar speed and stabiliy as my Sakura 0 S (7.5T motor, rear 3 deg toe-in).

However, there is one issue observed, steering. Any suggestion on improving TT01 on cornering.   

front solid diff and TRF suspension is must~~

乜你咁空閒既！

last night tried again at JV with my friend. I changed to a very badly sprayed ISF body in orange colour. Instead of SPIN, now it keeps non-stop 'cup 4'.. sometimes could roll for 5-6 times

May need to consider to re-setup the car again.....

放車真係唔易 ar...

翻車 ... 換 D 無咁咬既呔試左先 !

May be SOREX 36R is too much for me?

how about the ride high? (車高)
try to reduce the ride high to 5mm for front and rear

I am not sure how to adjust the ride height for TT01. Seems need some options A arms for downstop screw which I don't equip with now. That's why I installed a new so called 'racing' body and set the body as low as possible (while keeping the original ride height) but seems doesn't help much.

Anyway, may need to consider a less grip tyre or a softer spring/damper oil?

"放車真係唔易 ar..."

Yes.  You choose a beginner car which is design to run slow, and try to push it too fast.  The difficulty of doing this is expert or pro level.

You run 36R?  Maybe you should try 40R to see which is better.
Try some Protoform body too.

What is your ride height?

Finally, good luck.

Yes C-Hing. You are right. And I think 70% reason is my bad skills...

Anyway, I will try to first correct the cup 4 problem, then start practicing to increase the skills.

Ride height is pretty 'high' now I believe. Will check tonight.

Try harder tire compound and/or harder springs.

A set of good shocks will make it much easier to set ride height/tweak etc.

Hi RCSquare C-Hing, the ride height could be adjusted by the shocks solely?

Indeed I got an option metal shock from 'Kxn Chxen' at KWS.

Yes.  Ride height is usually adjusted by shock (mounting position, or adjusting collar/shims)

Some guys like to take challenge.  
The more problem you face and solve, the more you learn.
