loosen your diff a little.
set less punch on throttle.
set negative on throttle curve.
use a less powerful motor.
make sure your left/right balance is correct.作者: alfa156 時間: 2009-4-23 00:59
Many thanks for your tips.
By the bay, could you pls further elborate the left / right balance of the car? Do I need to use the 鉛 to balance the body? How can I measure the balance of the car? Or just try and error?作者: alfa156 時間: 2009-4-23 01:03
Below is my XII's configurations:
Hobbywing 9T brushless esc + motor
Pinon gear 24T
Main gear 96T
Front & rear tyres: ATS r32
Is lowering the body height helpful or not??作者: lung1 時間: 2009-4-23 01:11

left / right balance -> it depends on the size/weight of your receiver.
calculate the weight difference between the esc (with wires) and receiver, then place lead weight on the receiver side.
this assumes you play 4-cell NiMh作者: hardmankam 時間: 2009-4-23 11:35

"但係直路一落brake又spin, 真係吹漲..." ->
This is a feature of 2wd (rear wheel)!
Because when you brake, only the rear wheels are locked, while the front wheels are still spinning, so the weight transfer is not even between the rear and the front, causing the rear to spinout. Does your car always spin to only 1 direction? Usually I find the car spins towards the heavier side.
you may try the following:
- brake earlier to reduce speed into a turn (or take your finger off throttle earlier, let it glide into a turn)
- use less brake power
- pump the brakes (like ABS in a real car)
BTW: 2wd is a great way to train your finger!作者: 123456789 時間: 2009-5-7 11:26
Have the same problem playiing in Shek mon....
Tired different tightness on rear diff. Rear with lots of tire water, front only half or none.
What else can be done ? add weight ?
Tried adding smoother oil on Char char. Mine is L4.作者: EDI 時間: 2009-5-7 11:45
