So, first of all sketch out a rectangle using very light lines. It will be the body of our quadcopter.
Now draw the propellers and the sticks on which they are located.
Let’s work with details. In the front draw the action camera. Add some details to the body of quadcopter.
Erasing unnecessary guidelines draw out the body and camera using clear and dark lines.
Now draw out the the propellers of our quadcopter. Erase all the extra guidelines that we drew in the first steps.
And the final touches. Here we need to add shadows and some glare, using simple hatching.
It was a lesson on how to draw a quadcopter. By the way, this thing is so famous that it even appeared in several episodes of the mega popular series South Park.
