當年用這電車來殺油雞你信不信嗎？

Actually 1S Lipo will be lighter than 2S A123.
For Lipo, you will have to consider either 1Cell (3.7v) or 2Cells (7.4v).
The placement of batteries and choice of motor will be different for each setup.
Just a note: Lipo and A123 are not race legal ... this is just for fun (or testing purpose).
If you want to be legal, its better to use 4cell NiMh.

ching.....粒123唔好巨D?
想問ching 點解唔用電槍2cell果D?係咪唔夠A?
say hi to 上面想起番/有玩l3 ge ching, 想問有無一塊原整ge T板?

The smaller A123 cell only has 1100mah each.

C兄, 咁講法好似用返4 cells, 用返 brush motor 玩仲好玩喎.....
但呔有冇好介紹呢?

I also play 1:12 at TRC. I am using RC 12L4, Li-Po 7.4V and brushless.

Car : 12 L4
Battery : 7.4 V Byenergy 分体 4200mah 25C
ESC      : EC power 120A with sensor
Motor   : Dualsky 8.5T
Gear ratio  : 96T/22T
Tire diameter : 48 mm
It may run for over 9 min, after run the Volt arround 3.84 each cell.

Some photo for sharing.

Hi, Ching,

ECS--EC Power without fan is OK?  Will it really hot or not.

The ESC just a little bit warm.

But the motor will be hot without heat sink...?

Motor arround 70 degress

A123
adv. -> safe, fast charging, easy maintanence
disadv. ->  size is big

Lipo
adv. -> easy maintanence
disadv. -> can be dangerous, high cost

NiMh
adv. -> low cost, standard size
disadv. -> heavy, high maintanence

(these are just my opinions)

i choose A123 but different to find in kws
