銅頭 machine vs Brushless System

Brushless system cost more, but no worry no maintainance.

銅頭 machine.... is it too late to buy?  

Which one will you buy?  銅頭 machine or Burshless System?

Tell us your reason if you can.  Thanks!

暫時無刷嘅技術仍未發展成熟, 好似咩3.5R呀、4.5R呀, 就等於7T同9T摩打噤上下, 吾係人人玩得來, 而且玩無刷的話, 如果齒比吾正確, 個摩打一樣會燒, 所以呢, 睇你自己想點玩啦, 如果吾係要鬥車, 我諗都係玩有刷好D
(以上只是本人小小見解 )

Actually Novak is coming out with SS10.5R Pro = 19T, and SS13.5R Pro = 27T.  Both are ROAR legal.  Can race spec class and stock class.  

I won't go for 4.5R or 3.5R....

個人的經驗: 就算是普通摩打, 如果齒比不正確 (either undergear or overgear), 亦可以出現Overheat的現象, 每兩三排电就要用上一對碳擦, 而且銅頭亦須常常打磨, 其中所花的時间及精神是相當大的。當然如不覺得麻煩, 並且樂於此道, 那就不用說了。

so you vote for brushless?  you haven't voted yet.

今年TITC個個都用無刷, 仲駛諗

Totally agree!!  really get sick of those brushed system..... 最慘就係... 就算你唔介意摩打 performance 因為舊銅頭及炭刷以下跌，佢都會因為缺乏照料連旭都唔旭！死未？   What I'm talking is just after playing around 10 - 15 packs of batteries... then you've to service your motor again..... don't forget you've to use $$$ to buy those brushes..... which means servicing cost has to be taken into account as well.

exactly...so i just switch to brushless too ...and Lipo for the best output...

咁無刷會5會比較無咁易jam機
我見D 7T 8T好似打火機咁...

I think for long term playing brushless should be better in term of cost.

Brushless has no spark at all.

I voke Brushless also. I haven't heard that a brushless will burnt with wrong gear ratio. But of course protection will open!

I've voted for brushless already. Sorry that I haven't done it at the very beginning. I think when using both the brushed and brushless motors, you have to be careful with gear ratio. Under- or overgearing will not be good to both types of motors. Yet you have to account for the maintenace cost and effort you paid for the brushed motors. As a result, I'll go for bruhless one.

新手一問：齒比太大，摩打負荷太大，會過熱，呢個我明，但點解齒比太細都會過熱？

You always have to use full throttle if you're under-gearing... which means the motor always has to be in high-revs range which generates heat once again.

Super!

我成班Friend都轉玩無刷啦.... 一個字...長玩"平"....

如果d brushless 有d較慢既 version, 好似 23 / 27t 左右, 我都會用.
不過我果架 m 車而已.

唔同轉數無刷, 任君選擇

For those who selected "銅頭 machine", you may want to re-consider...

I bought a second-hand Novak 5800 brushless with the SS ESC.  Man.... that thing is fast, and I know I don't need to maintain it, so just basically battery and go   Too fast?  I can set the ESC to limit the motor to 24000rpm.  That equal to a good 23T??  I think.  

At our local hobby shop race, we use 13.5R for stock/27T, and 4300 for spec/19T race.  Brushless is the way to go!
