If budget permitted, why don't buy both of them?
Depite of similar chassis, they have totally different looking.
I've got two re-Hot Shot, and one original.
Later on, I'm going to buy my third Hot Shot and two Boomerang.

Yes, !!

啱啱好最后一部平嘢比我立埋, 都唔知點解個價可以咁海鮮
有D鋪簡值當人傻仔一樣賣九舊水,差成百蚊

想問下隻esc有内置BEC或要用BEC接收 ? thx.

BEC接收 is not required. (just a rational guess)

一般esc會做埋電源供應比rec
出 6v
而rec是用4.8v至6v
servo 亦是一般用4.8v至6v
由esc條線偷電

bec是
當年用機變(msc)
最最初是用5cell 6v 電玩車
另加4粒乾電共6v 比rec
之後為了方便 / 減車重
從msc偷線回rec比6v rec用
再之後興6cell 7.2v
故會高出rec之可用電壓而燒rec
就推出7.2v > 6v / 5v 之 bec 解決問題
都好多年前的事了

而現在接近所有esc
都是6v輸出去rec
故不用 bec了
但要是你仍用msc的話
就一定要rec內建bec了

thanks for input.

但係比 BEC 早約十年(八十年代初)，美國阿蘇士係1/12上面以經唔用接收電(因為以前0既接收同伺服器太大，冇空間放接收電)，係無段變速前，電池插加粒整流子，降壓到6V比電到接收(有錯請師兄們更正)

因睇過TOWER 話101BK ESC 要用BEC RX....所以才有此疑問.

我淨係知道雙星既101BK ESC條紅黑電源線是要插返入receiver 既BATT度, 隻電變先有反應.

If you use Tamiya 101BK, you must use a receiver with BEC or use an external BEC. The output of the red plug in 101BK is directly connected to the 7.2V supply.

If you connect the red plug to a receiver without BEC, it still works but at an operating voltage higher than the designed 6V (in fact, at 7.2V).

As such, the response of the steering servo is very fast (even it is 3003). However, no one know when the receiver or servo will be damaged. That's why TOWER 話101BK ESC 要用BEC RX
