ABOUT THE OPEN RACER4

The Open Racer 4 is made for race, inspired by the DRL Racer4, they share the same DNA and agility, but in a lighter and more powerful rig.

This drone is running in the world championship so you can be sure that the performances will be amazing!

You probably dreamed of having yours at home so we did it and it's open source!

We focused on the weight in particular because the original is not known for his weight and we succeeded to lowering the weight to less than 900 grams.
