Just for reference~
Don't be serious !!!
If you don't think it is accurate~ do u have any idea to show me that?
Thanks~

其實我有定案架喇,我會揾個電子單車錶,會有粒金屬定位係車軩,再喺臂上將一個和電子單車錶連線嘅感應器定位,
車軩每轉一圈,數據都由感應器送到電子錶,以測出較接近車速,不過,等我試一試先

電子單車錶~要set個wheel個diameter~
但係個setting 有無可以去到咁細呀?

Pretty excited for ur good attempt .. but u may try this link .. more helpful and easier to predict the actual speed with ur " Roll Out " concept .  Just plug in all required data then u can estimate either MPH or KPH

Hope it helps

咁呢度有無警察叔叔肯借呢用一用 ? he he !!

唔講唔知原來遙控車可以咁快。講開測車速，有個方法唔知可唔可行，搵個球場，搵條50m跑道，搵兩個人，每人一隻錶（事先對好時間），企係跑道頭尾，記錄你部車經過跑道頭及跑道尾既時間…^^"。其實即係用最基本，速度既定義：距離／時間。

紅星有雷射愴買！

test temp or test speed ?
