Hello Friends,

I am planning to build an RC car but do not have much idea on how to select appropriate motor / speed controller for it.
I am not looking for much speed (probably 10-15 km/h), but car should able to carry total weight load of approximately 2 to 3 kg. Power efficient motors would be added advantage!

I do not have much idea on where to start so any pointers would be much appreciated.

Thank You.

Hello Nanu,

Thanks for the reply.
1/8 scale scratch built most probably. I could also consider 1/10 scale.

Thank You.

anything between 60amps for 1/10 scale, and for 1/8 I recommend min 100Amp ESC.
And a matching motor, this is with 2S LiPo on the 1/10 and 4S or even 3S on the 1/8th.

Also consider ur gearing ratios.

It'd help us if you could specify the approximate weight and gear ratios.

To get an idea, take a look at 1:8 E-buggies and truggies.
