final gear ratio: 1.9 x 80/20 = 7.6, then which track u raced? and after each run, u need to check the spur gear and motor gear to see if there will be some sands attached on the gear. it will damage your spur gear. 作者: chui 時間: 2012-2-16 19:48
近排我都掃咗兩次齒,開頭都以為3racing啲齒唔得。但最後發覺係下面果粒摩打羅絲會震鬆。落羅絲膠同每次換電check吓有冇鬆到。(只係個人經歷)作者: eric3037 時間: 2012-2-17 11:42
我都覺原裝大減都好耐用作者: bb406406 時間: 2012-2-17 11:48
可能關你個摩打事,要睇下條摩打心有無變蘋果心,我試過一排電一隻大減作者: bunpong 時間: 2012-2-17 12:52
再可跟下摩打座有冇撞過而變形,最好拆下來放在平面上才可知道的!
大減旁邊細齒如果是原裝用得耐都會令大減搖的!
