Out to fly today, but didn't get airborn - flight controller was complaining of a motor problem. Packed up, came home, hooked the drone up to MK-Tool, no errors reported but motor test shows no response from motors 2, 3 and 5. Drone config per below. Had time to do a quick connection test of the bullet connectors - all seem fine. Given that I'm Canadian, I had to head out and am now sitting at the hockey rink for my daughter's practice. Googling and thinking what are likely causes. Thoughts?
