Aerodynamics For Fast Electric RC Cars

Exclusive Summary About Fast Electric RC Cars by Niranjan Pradhan

Speed thrills and that is why fast electric rc cars are popular among radio controlled hobbyists. You will see how and why the aerodynamics of a fast electric rc car plays such a pivotal role in designing the vehicle.

The relationship above means that on a surface like that of your fast electric rc cars body if the velocity of air increases then the pressure exerted on that surface would reduce. You have two surfaces of your rc car.

When the car rushes through air in one direction essentially air flows along the surfaces in opposite direction. As per the principle above with decrease in speed the pressure on top surface increases. RC sprint cars have a very high speed to weight ratio.

Over steer / Under steer Tuning tips

Exclusive Summary About RC Car Set Up by Gregory Alexander

There are a lot of ways to tune the handling or your radio controlled car, the easiest is to adjust the front and rear shocks. While there are a lot of options with springs, different oils and all sorts we are just going to concentrate on the basics, most decent shocks have adjustments, either with spacers or bolts that let you adjust how hard or soft the shocks are.

As far as maximum and minimum stiffness goes, make sure that the bottom of your car doesn’t scrape the ground, and on the other end make sure it doesn’t bounce and leave the asphalt, apart from that you need to find the setup that matches your driving style, most people get winning setups off the internet and try to learn to drive them, mind you this is a great starting point, and most championship winners post their setup sheets.

Shock Stiffness guide

Stiffen in front = increasing under steer or reducing over steer
Stiffen in rear = increasing over steer or reducing under steer
