bought new F-1 .but im not happy

hi i just bought my first F-1 readyset .open it and there is two problem (i use 3PK RX )

-first problem turn power on the wheel is all the way to the right .use the RX set trim to 89% to the left . the car still go right. set at 90% trim the car will go left. it just wouldnt go straight?????????? any one know if the F-1 pcb can adjust steering neutral???????

-second problem the diff dont work .it run so bad so noisy .(i have 5 other mini-z so i can tell it is bad).everytime the throttle go over 30% the car will spin out.

i really dont expect a NEW F-1 to have problem

can any one help

I suppose you have the AM board.
Using transmitter other than KO then the center will shift alot. You will need sub-trim or cali the trimmer on the AM board to bring back center.
Go get a ball diff for F1 than the world will silent again. Be happy ^^

hey, the reason why the diff. so noisy cos' it's so new...i hv this problem while mine was new, after i add a bit diff. oil and run for a couple of times, the noise is less now. And the other thing why the car will spin out is that using the original tires are not OK. If u want to play it on a carpet, change the front tire to 20 deg. and rear to 10 deg (go for Atomic ones), u will tell the difference then...

i take the F-1 apart and trim the steering center on the PCB.
the diff ...i put some diff gear (the three small inside ) from my old MR-02 than it OK.
i think kyosho should have better QC .
