銅頭 machine vs Brushless System

I'm a lazy guy, that's why I choose BL. For gear ratio, actually instruction from manufacturer already provide a suitable gear ratio range, it also make the setup much easier.

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  ...

HOW MUCH YOU PAY FOR THE NOVAK 5800 BL WITH SS ESC  ?

Brushless is the way~~

i just got my Mamba Max ESC too.....will test it this weekend....

i can see the tire is ballooning~~~..heheeh

Congrats and enjoy it.  Please tell us your test report of Mamba Max ESC.

Yes...will do it this SAT......

Here are some pics~

4.5 BL for 6 cells is too fast, few fans use 3.5R in four cells to reduce the speed, the performance is fruitful.....good for novice or 23T brush motor lovers..

Why they don't use 6.5 or even 7.5 lei?
Or your friend use a 4 cell version GTB?

多謝解答^^。咁我墊高車底、四輪離地、空轉黎試車咪好傷麼打？

問得好... 玩車都要食腦, 千祈唔好人地講乜你就信乜...

If you use full throttle a lot, it's likely to be.

This is different from what Binary is saying. Your motor is not loaded under the condition that you've mentioned. The motor is worked with the resistance of the driving system only. When you run the car on the ground with full throttle, the motor is loaded with the resistance of the driving system plus the whole weight of the car itself. They are totally different!

我係新手，對呢方面認識不深，多謝各位指教。其實係咪即係咁：負荷太大，當然會傷麼打，但負荷太細（例如我用一隻好細既麼打齒去推一隻大齒），都會傷麼打？

Yeah.... absolutely!!  

From my experience, "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." is correct.  The correct gear ratio is very important.  if overgear ratio, the motor need higher revs to keep the same speed.  With loading condition, u will observe part of the communator become from gold color to red color....If undergear ratio, even u full throtlle, the car cannot run fast...in this siutation, high current but low revs...the motor will be very hot and low efficiency...harm to motor too...

"咁我墊高車底、四輪離地、空轉黎試車咪好傷麼打？"  It depends how long u do the test...but why u need to test your car with full throttle withoput loading condition....Its meaningless...anyway, if u just test it few seconds, its no harm....

stupid boy, under gear   行車架車係有loading, 唔同四輪離地空轉, 係有機會過熱的.
