okay so im thinking of buying a rc nirto petrol car and i dont know what the brushless things is and what it does, is it better to buy one with it or without ? ¬_¬

Answer
nitro rc cars dont have brushes at all its only electric rc cars which have them, they are inside the motor of an electric rc car so that the car can go fast, (electromagnet)

What will be the speed of a RC car with 500 RPM?

Q. I am planning to make a RC car with 4 wheel drive and a geared DC motor. I need to know what will its maximum speed be. Thanks in advance.
If I want 45-50km/h then what motor, battery, wheel size should I use?

Answer
I just read this over at RCU,not to fast,the bigger diameter the tires the more top end,the more teeth on the pinion gear mixed with less teeth on the final drive the more top end.Vise vers for low end.Wich is of the line.500 rpms is not fast considering there's a 3.0 turn brushless motor made that spins over 84,000 rpm's.Your best bet is to get a roller of ebay or RCU slap a high rmp motor in it some servos and experiment.Also keep in mind with electric,the more turns the motor is the less rpm's it spins.+ brushless motors turn way higher r's as to brushed motors.
