请问各位: 我准备买一个充电器,我是新手,我也读了关于充电器的文章. 说充电器是比较重要. 请问这样的充电器可以吗? Digital Auto Peak DC Charger Input voltage power source - DC 12V battery 5A Output - can charge 1.2 ~8.4V (1- 7cells) battery - charge Ni-cd / Ni-Mh 110mAh~ 3300mAh - can charge battery of 1: 24, 1: 28 , Mini-Z - Current: 0.6~4.5A (adjustable) - High efficiency, control charge/discharge current with pulses (NOT resistors!)

以下是引用chen268107在2004-12-6 8:08:30的发言: 理论上说gear ratio越小速度越快,但是过小的ratio会损坏电动机和调速器的。 一般每一款车对于不同电动机的gear ratio会有一个建议的范围,一般就在这个范围里就行乐。但要考虑每个电动机的实际特性(所以我们需要像mms这样的马达测试仪),场地的大小,比赛时间的长短和你的操控习惯等其他因素来做决定。 由于每一个款车的固定减速比是不同,即使是同样的gear ratio也会是不同的大小齿搭配,这个在使用的时候是需要注意的。 |
