As the time goes by, the drones have became more and more mature, in the past ten years, we are only can play rc planes in sight, but now we can through GPS to control our planes out of sight or Further, and now the FPV drone has been more and more popular, there were many FPV racing in the world in 2016. FPV drone is a mini quadcopter, Pilots through VR glasses to control their drones. Next let’s know the history of mini quad racing.
The explosion of this racing aspect of the hobby has to go back to the development of “mini quad”. Before that people were mainly flying larger 450mm sized quadcopters and hexecopters.
The 450 quadcopters are heavier, and they lack the agility and durability (in crashes) compared to a racing smaller 250mm size mini quad. Mini quad are made for crashing, so even when you crash you can usually just pick it up and fly again within seconds. This gives pilots the confidence, and allows them to fly faster, through smaller gaps, and pushing their limits to the next level.
The numbers 250, 450 etc, is the diagonal motor to motor distance, basically that indicates the size of the multicopter.
Since then, we’ve seen huge progress in the horse power of these mini quad, increasing propeller sizes, higher LiPo battery voltage, larger motors… Some insane power to weight ratios of over 10:1 is becoming possible, turning these little toys into insane rockets, which are capable of reaching 80 miles/hour (~125Km/hr).
