battery is very important too~if you want to be faster.

and what is the model of your ep ar?

[ 本帖最後由 mark999hk 於 2007-8-12 12:03 編輯 ]

TA05-IFS and battery Intellect 4200

Motor is Tamiya Super Stock TZ.

charger is important too. Good ESC can also make it faster.

Why charger is important?? I thought all the charger can fully charged the battery and therfore should be the same........

Also, what determine as a good ESC and any recommedation???

THANKS!!!

most important thing, whats yr budget XD?

Good charger can peak charge battery well (higher capacity, higher battery voltage and make it more punchy).

Lower mosfet Rdson ESC can make the car more punchy and faster (lower voltage drop from battery to motor).

Cheap one $2xx is V16 which has very low mosfet Rdson but linearity is not good though.

Money is the most important

请问你大齿用几大,摩打齿又几大呢?
什麽场地?直路好长还是多湾?

I play that in TRC. Spur Gear 70 and pinion gear 27.

可以試104搭41-43齒作起步位,前後加減摩打齒數來試到剛好為止,數是這樣算的104除41乘2.25=5.7,直路唔夠時可以用到5.4

Thanks!!! But what if I change the pinion gear to 28??? Then 70/28*2.25 = 5.625.... Will that be the same as 104 with 41????

只是齒距不同,你用48pitch我用64pitch,而以上這個ratio只是起步點嚴唔夠快可以再加大多兩三齒,但要留意出灣又會淋d最終都要臨場試因為每架車的重量,電的質量都唔同嘛沒有一個一定的數字
