请教各位师兄我块AD BAND 叠左九层4526 用STOCK R 可吾可以用AAA锂电啊

我估只要電壓唔超過 6V 就得。

听讲好似有D叫降压电阻葛野吾知WORK吾WORK

就咁電阻一定唔得。(除非你想架車一路跑，一路烘麵包咁樣....)
電子火牛降壓都唔多得，出輸功率唔夠大。(通常D火牛仔只夠手機充電、USB取電、LED燈呢D小野用)
架車都爆唔起。
同埋唔係越多 fet 越好。較重要o既係考慮摩打處理、散熱....

就算用到都无咩意义．．我试过０２用里电快到翻车．．．好玩咩？

suggest you keep it under 7.4, because 1)the steering motor will be too fast for the board to respond, making it jumpy, 2)the motor will be way too hot even if the supension can take it. if you really have confedence in your motor and throttle, use external FETs like the v2.2. By the way, while having that many FET may increase your torque, i don't think it is that significant over 4x2, and the throttle becomes unstable by then. motors you can fit in a Mini-Z rarely even need 3x2

Li-po cells are usually 3.7 each. If you use one cell, I don't think the steering will respond well. If you use 2 cells, they will give you a voltage as high as 8.4 volts when fully charged. AD board can handle 10 v at maximum while a normal AM pcb can only tolerate 7v (one of the cap. indicated that).

I have 2 cars running on a 7.4 v li-po and AD band and they do well (one shown on the left). All you have to do is to change the fets and turn to motors with more turns. A 50-turn motor can already be terribly fast.
