Now I'm going out on a limb here, but apparently at the USA repair station in Ontario, California. There seems to be a problem of quality control at our US repair station. This can probably be resolved by a better checklist or arbitrarily just checking off the boxes by some of our technicians. At present I have a RMA from Yuneec to return my typhoon H. I am really really scared to return my drone. What do you think should I return it or not?
