5 tips to make your RC car go faster
One of the most popular topics in RC is speed.Experienced hobbyists prefer to point how two questions when they see an RC running: how fast and how much? we’re all a little obsessed with speed, and more specifically, going faster. Check out these five top ways for going for faster with your electric ride.
Higher Kv or Lower Turn Motor
This is the old fashion way to get more speed–add horsepower. Most brushless motors have Kv rating and the higher the Kv rating, the more rpm a motor will put out per volt. If the Kv rating isn’t listed, a turn rating will often be used. With brushed and brushless motors, a lower turn rating equals more rpm. Always check the limits of your speed control before installing a “hotter” motor. Increasing your motor’s Kv rating 2,200Kv can yield an increase of 20mph if your are using the same brand and model motor and have batteries that can supply the needed juice.
Higher Voltage Battery
To do this,get 3 or 6 rechargeable 9-volt batteries. Connect them in series pairs - gens ace 2s lipo batteries to make 18 volts, then two more in series, with this series connected in parallel to the first.for example, go from a 2S (2-cell) LiPo to a 3S 11.1v LiPo battery. This jump from 7.4 volts to 11.1 volts can increase speed by as much as 25mph! The more batteries you have in series, the faster it will go. The more you have in parallel, the longer it will run. By the way, make sure your speed control can handle the extra voltage or the only thing you’ll be fast is going to the hobby shop for a new speed control. You’ll also want to make sure your chassis can accommodate the the larger pack.
If you’re only going 25mph, aerodynamics aren’t going to play too noticeable of a role. If you’re going 50mph, aerodynamics will certainly start becoming influential on top speed. In addition to mounting a low profile, sleek body shell, mount it as low as possible and keep the wheel wells as small as possible. Open up the rear of the body to let trapped air to escape.
Better Grip Tires
All the extra power won’t do you much good if you can put the power to the ground and put it to use. Invest in some high-quality aftermarket tires in a soft compound and you’ll be going faster.
Spend some time practicing the handling of your car out on the track. If you want your car to go faster, then you probably plan on racing it or you’ve been racing it. The winner of the race isn’t necessarily the person with the best car, but the person who has the best handling car and can best tackle the track. Find ways to get around the track easier and you’ll get faster lap times.
