XRAY - Model racing cars

Running Xray t2 009 indoor and having major oversteer problems going through chicanes. The car handles great everywhere else but I get to the chicane and it's so loose I have to slow down and crawl through.

Settings : -

Downstops : 6 Front , 5 Rear
1.5 Camber all around
0.5 degree toe front
2 degree toe rear
1.6 roll bar front , 1.4 rear
6mm ride height all around

I'm not so sure on the track width, on the front there are small shims used but on the rear no shims used. Could this be the problem ?

Try standing the shocks up more.

Try a bit more rear toe first... 2 degrees!!! Step up too 2.5 then if better but still not amazing 3 degrees

If the car is great everywhere, may you turn more that you really need.
Also you can try 3º rear toe as they say, car more estable, little less rear traction.

Widen your front track width. Try a softer front anti-roll bar for less turn-in. Decrease your ride height.

Hello guys,i have a problem like our friend of understeer on asphalt track,when i turn into a hairpin with some speed the car is unstable so i have to slow down to stay at the correct position,my friends cars are very different in their handling,they go at high speed in the hairpins

......................PLEASE HELP.......................

Hello robabela.

Try a harder rear anti roll bars, for get less rear grip. This is very good in harpains corners.

Check your maximum radio of steering 25º.

Thks for your reply Ruben_qlc,,so i need to change the rear anti roll bar?

Here is my setup for xray t3 with speed passion motor 10.5
front down stop front 6 rear 5
front camber front 2° rear 3.5°
front reight height 5.5 rear 6
front toe 2° rear 3.5°
shocks in middle hole all around,oil front 400cst rear 350cst
diff front solid rear oil 700cst
gear ratio FDR 4.3 pinion-42t 64p spur-96t 64p
antiroll bars none

How can i calculate the FDR with our track,there is a sum or A MATHEMATIC calculation something like that?
PLEASE ADVICE.
THANKS A LOT MY DEAR FRIENDS, XRAY 4 EVER, ALL D BEST!

You calculate your FDR by spur/pinon * 1.9 (internal gear ratio of T3-T4).

Increase your rear uptravel (downstop) to 4. This will allow more weight to be transferred to the front wheels under braking, which makes the car turn in better particularly in hairpin corners.

Thks for your reply ALEX i`ll try it for shure in training next time! Up travel you mean down stop wright? Cheers! Thks a lot mates!

XRAY and a lot of people in RC refer to it as droop and lot of other people refer to it as uplift. It is affected by ride height and by your downstop screws

Thks mates!
