Guys my car always sliding at corner.What do need to set?

sliding on mid corner or corner exit ???

1. mebi your tyre not suitable for the track
2. Track traction not good
3. you car suspension bind
4. your car's rear is losing traction / tyre overheating

solution :
1. try diff tyre shore like 36 -40 but this depend on ur track temperature
2. check if your suspension binding or not ....exp = hinge Pin bend , shock oil dry up or dirty
3. try make your front spring harder than rear 1 level....this will make d car's rear more grip.
4, increase the thickness of ur stabilizer for front..

Hi, M not an expert. From what I gathered this "sliding" could be the result of traction (or the lack of it), weight transfer as well as how fast the chassis changed its direction

Where did you have this problem? is it entry into corner? Mid corner? Or exit?


- 1st rule of engagement: is the tyre of the correct setup? (Type/hardness + insert + wall stiffness)
- 2nd rule: if tyre setup is ok, then look at weight transfer and contact patch. -reduce front grip or add rear grip:
-add toe in the rear (3 degree is normal);
-add more camber (shorten the camber link, 2-3 degree is normal) + camber change rate (move the camber link mounting points closer/change camber link mounting position- higher @ the hub, lower @ tower) in the rear; (opposite for front)
-softer spring + softer dampening in the rear, harder in front; (opposite for front)
-lower role centre in the rear, higher in front.
-play with chassis weight distribution (move more weight back to increase traction @ rear).... but that can increase pendulum effect.

... (agreed with all Kschu points)... plus make changes on one variable @ a time

i PLAY at HPC Glenmarie.I use sorex40.I think my rear suspensian too hard.I think i have to get a soft one.I use to use tc4.That one i set up ready.Now this one my figure out how to set

evollace

what insert u'r using? thick, hard insert could reduce grip.
also check the car's rear diff. too tight may induce "sliding" as well.

... also try to increase front drop, reduce the rear's

You can try all that is advised by kschu and evollace. They all help in reducing oversteer.

HPC is a medium to high traction track. So, I am guessing that you are having oversteer at corner entry. For me personally, I'd adjust the anti roll bar first (harden the front or soften the rear). Then I'd adjust the roll centre (higher roll centre at the rear so that the car rolls more and have more grip). If it still oversteers, I'd adjust the wheelbase. If the problem persists (very unlikely), only then will I check springs, shock rebound, downstop etc etc etc. But remember, adjust one thing at a time. Then you'll know the effect of each of your adjustments.

The above are all assuming that the tires are in gd working condition. I usually use Sorex 36R with soft/med soft insert in HPC.

Saya ni pun baru sangat nak main ep. Sebelum ni main buggy. Nak tanya sket la, Motor 23T tu apa maknanya? lagu banyak turn lagi bagus ke atau sebaliknya? lagi satu, brushless motor ngan brushed motor ada beza sangat ke, selain dari harga la..

lagi satu, kete EP guna shaft ngan belting, yang mana satu lagi ok?

Motor punye turn lagi kurang lagi laju tapi. Race kat malaysia biasa pakai BrushED MOTOR 23T/Brushless 11.5t.Brushed dia kena service brush dia setiap 10 full battery run.Brushless tak payah kisah apa apa.Main je.Shaft dengan belt tak banyak beza.Maintainance die dengan bunyi dia.Shaft bunyi dia kuat sikit.Belt bunyi dia kurang.

Selalunya kalau brushless motor nak kena guna berapa amp punya esc? da sesiapa yang boleh tolong bagitau?

Feizal....motor 23 turn ialah motor yang biasa digunakan untuk kategori stok kat M'sia ni. Motor ni ialah "brush" motor, so kena selalu cuci, comm dan tukar brush dia. Byk hal sikit nak jaga motor brush ni. Kalau kategori "modified", racers biasa pakai motor turn yang lebih rendah seperti 10t, 9t, 8t, 7t.

Motor brushless ialah technology baru....so mahal ler sikit. Utk kategori stok di Malaysia ni, kita pakai 11.5 turn. Speed dia lebih sikit dari motor "brush" 23t. Brushless ni senang sikit penjagaannya sbb tak payah cuci selalu, tak payah comm dan tak payah tukar brush sbb takda brush pun. Brushless 11.5t ni pun laju lagi sbb dia efficient, takda drag and tak panas sgt, tak macam brush motor yang ada drag disebabkan brush and comm bergeser yg juga buat motor ni panas.

Keta TC yang shaft-drive dipercayai lebih bagus digunapakai utk stok racing. Sbb motor stok ni tak se-power motor modified, keta shaft-drive ni boleh bantu dari segi torque. Tapi keta belt-drive lebih efficient. Sbb tu kalau kau tgk kat hobby shops, kebanyakan TC car kits sekarang ni adalah belt-drive.

Kalo nak beli esc, beli aje ler esc untuk brushless motor. Melambak2 kat hobby shops. Tanya aje tokey kedai tu. Tapi kalo ko nak racing, nak selamat and x rugi duit, belilah yang top-of-the-line punye.

terima kasih bro shahrin sebab beri penjelasan yang terang dan jelas. Baru le jelas sket. Pasni leh la saya cari brushless motor. Biasanya kalau race, orang yang pakai motor yg lagi kurang turn ada peluang cerah la nak menang, sebab kete mereka lagi laju..camtu ke?

Bro, kat race semua orang pakai 11.5t.Itu ruling dia.Dia laju laju tu dia punya gearing ratio dia,Setting dia.Kereta say semua sudah set.Skrg cuma i kena practise i punya driving.

camtu rupanya..gearing ratio memang boleh pening kepala..

shahrin

Depend pada class mana kau masuk race. Kat East Asia ni (termasuk Malaysia), ada 2 class aje - Stock 23t brush /11.5t brushless dan modified (no limit). Tapi kat Malaysia ni, sejak kebelakangan ni org race in Stock class aje.

Kalau in US atau Europe, depa ada 3 class - Stock 27t brush/13.5t brushless, Superstock 19t brush/10.5t brushless dan modified (no limit).

Since sume pakai motor turn yg sama dalam Stock class, nak laju kena main ratio ler. Tapi bukan tu aje, bateri pun memainkan peranan juge.

camtu..satu lagi, esc brushless yang kata ada limit sampai 5t tu apa maknanya? Sensored brushless tu apa bezanya dengan sensorless?
