Hi-Speed DC Motor for Toy Car.

[sidy50]

Hi Guyz...
I was recently trying to built a Remote Control High Speed Toy Car...
I have completed with Software Coding for the Joystick Control & PWM...
Now Im Stuck with the motor part...Which motor should i use to get a good speed for the car near about 50-100kmph...
I have seen videos on youtube about Electric toy cars running @ about 73mph Blazin fast...And these cars look like simple RC cars...
Please tell me how can i increase the speed of the car to such desired level.

Thanx & Regards.
Sidy.

Several tactics for maximum speed.

* Large diameter wheels (rather than small diameter)

* Step-up gearbox

* 5, 6, 7, 8, 9 or more turns motor (rather than only 3)

* High performance motor (Cobalt, etc.)

* Minimize power losses in wiring, etc.

* Use a speed control that revs up to 100% current flow

* Use lightweight construction for quick acceleration, yet not so light as to lose traction.
