想問下如果用同一隻摩打
但用不同A數輸出的電變
咁大A數輸出的電變會否比細A數的電變快

The speed should be no different for thesame motor.
A faster motor will need an ESC of higher Ampere output so that enough power can be supplied. If a fast motor is equipped with a ESC of small ampere, then there is not enough power to supply. The fast motor will be slow.

我個人覺得會快ddddddd，但你會唔覺。
通常輸出細既esc的內阻比較大，電壓降亦比較多，有部份POWER會消耗左變成熱力，電流愈大就愈熱。所以能力許可就買個靚d既 esc。

以上唔知有幾多成對呢

理論上, 電流係用幾多要幾多
多 o左 o既會用唔到, 所以你用咩電變去玩隻白豬, 隻白豬都唔會有分別
因為白豬用唔晒 o甘大電流

1. Theoretical, you are right.
2. The amount of current depends on the supply voltage and internal resistance of battery, esc and motor. Obey the simple ohm's law, I = V/R. As the internal resistance cannot be controlled, you can only control the current by adjusting the voltage. However, you cannot provide a voltage higher than the norminal 7.2V.
