有刷摩打齒比

請問邊位師兄有有刷摩打建議齒比 ?

幾多t????????

我都想知
11t
12t
13t
9t
8t

龍哥 6T ~ 12T. Thanks !

13T final ratio=(6.7~7.0)
12T final ratio=(7.0~7.3)
11T final ratio=(7.3~7.8)
10T final ratio=(7.8~8.2
9T   final ratio=(8.2~8.7)
8T   final ratio=(8.7~9.5)

唔該 vvti

咁 Single 同 double 的齒比有無分別 ?

係咪唔同t數嘅摩打要用唔同齒比？ why? 如果唔知隻摩打幾多t點辦? 我架係ta03R...可以用什麽齒呢，普通落街同個仔玩吓會有問題嗎？會唔會燒電變？

唔知摩下幾turn咪用d高少少嘅齒比試下先囉, 雖然慢d但係唔會燒野

你部ta-03R用原裝白豬(成個摩打銀色冇寫野)?

我架TA03R係二手買返黎，玩咗無耐，電變出煙燒咗，買咗個全新Futaba MC330R ESC 裝返落去, 又到個摩打柴咗(Pro Stock 15T), 之前買個舊控送咗個舊摩打，貼紙無咗一半，唔知幾多turn..但係都幾快, 但係玩一陣(約5分鍾)嗰Esc同舊電(鋰電)勁熱, 連所有電線都勁熱，跟住出現腳軟情況(即係架車慢晒同有d失控...點解會咁???

咁可能係個電變根本頂唔順你個摩打, 個摩打太底turn啦, 最好都係唔好再用呢個摩打落呢個電變度, 費事燒野 ^^'

如果真係要試的話可以用d好高嘅齒比(eg over 9.5), 同埋試嗰陣唔好比太多油, 睇下仲有冇呢個情況出現

什麼是齒比？如何計算？我摩打係23齒!

since TA03 is old design and having a lot of gears, calculating gear ratio is a bit ma farn. you have to count how many tooth each gear has, than find the transition ratio by:
1) transition ratio = number of teeth in 2nd gear/number of teeth in 1st gear
2) multiplies all the transition ratios

if you are using the original gears, the following (page 9) is the gear ratio chart
http://www.tamiya.com/english/rc/rcmanual/58254raybrig.pdf
from the chart 23t pinion is 5.18 ^^' its a very low ratio, thats why everything are hot.

唔該呀C-hing...咁係咪我個摩打應該換返小d齒數就會無咁熱？同埋1齒係波箱大齒，2齒係摩打齒？

以11T 摩打做例子:final ratio=(7.3~7.8)....

Single Wind :低轉扭力大,咁齒比可以用比較大D或者有人說低D.(例如:final ratio:7.3)......
Multi  Wind  :低扭較弱，要到高轉數才能發揮,就好似vtec咁有尾段,相對上齒比可以用比較細D或者有人說高D..(例如:final ratio:7.8)......

什麼是齒比？看圖 http://www3.kcn.ne.jp/~tobee/gyahi2.htm
如何計算？傳動減速比(內齒比)x (從動齒輪齒數 / 主動齒輪齒數) = 最終行駛比率。

係咪唔同t數嘅摩打要用唔同齒比？ why? 如果唔知隻摩打幾多t點辦? 我架係ta03R...可以用什麽齒呢，普通落街同個仔玩吓會有問題嗎？會唔會燒電變？

Thank you vvti C-hing...thank you so much.
