Radar Gun Kit - Build Your Own Radar Gun!
RC cars and trucks are fast. But really, how fast does your rc car go? You can make estimates such as timing how long it takes for an rc car to travel a certain distance.
But there is an easier and faster way to check the speed of your radio control car. And that is to use a radar gun.
However, most police radar guns cost hundreds of dollars.
Fortunately, there is now a radar gun kit that you can buy for less than $50. If you are into building science kits, then building this radar gun would be fast and easy.
When done, you can clock the speed of rc cars, trucks, boats, and airplanes. The LED displays speed in miles per hour (MPH), kilometers per hour (KPH), and even feet per second.
