Is the prop guard 3D printed? I wonder which market-available prop guard can work on m500.

Hi, I want to order a m500 drone and have it send to Illinois. How fast is the arrival? Does it take 10 days to arrive as described on the purchase link? Is there a express delivery option?

Thank you. Also for the purchase delivery, how fast can a m500 order arrive to Illinois? 10days? Is express delivery available?

Hi, I am planning on putting four acoustic sensors from Maxbotix on m500. Should I create a customized ROS node for accessing the readings from these added sensors? I plan on communicating the data feedback from the acoustic sensors wirelessly and do calculations on my ground PC. Does it have anything to do with PX4? What are the default nodes that come with VOXL FLIGHT? Sorry I am new to this field.
