So I came across a course on youtube about simulation of drones in Simulink. After i saw the video about selection of motors based on no load rpm and voltage graph. But I couldn't understand how he got the relation between voltage percentage drop linear and no load rpm. If anyone can help me understand the the relation between them it would be very helpful. I have the excel link in starting. Thank you
Hello guys! I have a problem and I hope you could help me. Didn't know where to go to ask a question so I turned on you. I have Wizard220x bought it from a firend worked perfectly.
