請問12仔用3.7V Lipo電會用幾turn brushless?

用3.7V玩？唔會嘛？

IFMAR regulation changed?

Even you use 3.5R in order to have speed gained, the efficiency will be low as it isn't the purpose of those high speed motor designed for....any valid reason to use 3.7V

Can't see the reason to use 1S.....

Westerners are trying out 1S + 10.5R.  The speed is similar to 4Nimh + 13.5R
With 1S lipo, the car is lighter and less wear on the tires.

Lipo itself is very light. I think the different between 1S and 2S isn't significant. But the speed will be highly affected. In addition, ESC may need something to do to cope with the lowered voltage. Still don't understand the advantage of using 1S......

The problem of 2S is not the weight, but the size of lipo.  If they can make 2S smaller with a high C and high mah, then it is much more flexible than 1S.

There are small size 2S. IP and Energy; one piece or split type...

I am using Novak 10.5R, 1800mah, 25C, playing more than 15 mins...
