標題: upgrading tomy caul
I just got a tomy caul car. it looks so cool but pretty slow. so i changed a tamiya 4wd high torque motor to it n hope to make it faster.
finally done!! It runs faster but i need to push it at the beginning. Otherwise it doesn't have enough power to make the motor run.

I wanna know does this motor fit to caul car? Or maybe i need to add some cap on it(not sure is it the way to make it work).

這是電流不足的緣故：
CAUL's pcb係不能推動多過1,200mah嘅摩打，你可以修改pcb增大電流（比較麻煩），或可考慮增加輸入電壓，如串聯多兩個AAA電，不過要用Toyota Hiace殼，其他殼未必够位。但改鋰電就無需換殼：http://bbs.rc-evo.com/viewthread.php?tid=85464&extra=page%3D3
由於架車設計唔咬地、轉向不足，越係改快就越甩！

if i add 1 more aaa battery (to be 3.6v) , will it over voltage and burned the pcb ? i dono the working voltage of that pcb. and also 轉向不足 is a big problem of this car. the front servo's power is so weak. how to fix it.

輸入3.6v電壓不會燒pcb (but do not use more than 4 charging batteries/total 4.8V)，當電壓增大轉向動力同時加大。
Rev-Tuned Motor is better than Torque-Tuned Motor when playing in this car.

why" Rev-Tuned Motor is better than Torque-Tuned Motor when playing in this car." ? what different to Torque-Tuned Motor?
And it seems to be hard to install additional aaa battery to the car. it doesnt has enough space inside. i m still looking for a cell phone battery can fit to the car. maybe .... can i install different kind size of 1.5v battery to the car. like bitcharG battery or coin size battery?

CAUL設計好有問題：
轉向不足又唔咬地，用高扭力摩打起步果陣尾轆咪打滑、部車咪左甩右甩，都唔可以好靈活控制喥佢响細地方；但係用高轉速摩打起步果陣柔啲、尾轆食到力，部車到極速果陣時咪入到靚彎囉！但只岩係大地方玩。
用Hiace殼玩就够位加2粒3A電，部份SUV可加到1粒，其餘跑房只可改用鋰電。
你可嘗試其他size充電，不過留意容量，用Char-G電、鈕電玩唔得幾耐。
另外，個IR接收器駁線出車頂接收會強好多！

thx for your comment.

I added 1 additional aaa battery to the car and used the regular motor. coz of the extra power that make it runs faster than b4. i didnt upgraded the motor .so far it still has enough traction.so 尾轆起步不打滑. Only a little 打滑 during 入彎 but not so serious. The steering improved. (it can turn to the end point finally

)

And like what u said "由於架車設計唔咬地、轉向不足，越係改快就越甩！" so i don't suggest to change the motor.

what kind of model 鋰電 can fit to the car. does all 3.7v Li-ion battery(cell phone or D cam battery ) can use the same charger?

E架野我覺得改左都唔多掂....=.=

幾十蚊貨仔,係咁上下架喇,原裝都ok啦,加多粒電已經夠玩

不過我覺得HIACE E款殼幾好
