Your can and have to, to set settings in the GUI, what I do to test motors my friend!
First, you DON'T "have to, to set settings in GUI". In regards to settings, it would make no difference. Second, you're not a technician. If you want to take the chance of damaging your motors (and, yes, you ARE taking that chance), then you have a right to do that...however, don't go suggesting others should do that. Talk with any drone technician, and they WILL tell you to NEVER start the Typhoon H motors without props attached. Again, the ESC detects resistance, which is how it detects a motor failure, thus the ESC will be tricked into believing that at least one motor (if not more) has failed Before you continue giving out "advice" that can potential damage other people's drones, you should consider contacting Yuneec, & talking with their technicians about the matter...unless, that is, you have no morals, care less about other people & their property, and are just looking forward to people who have followed your "advice" coming after you, due to their drone being damaged (or worse).
