@dmars2001 To add a little more info: I took the "good" motors off another codrone that works find and put it on the drone that is not working consistently, and I was having the same problem, so it might be a problem with the drone itself, not the motors.

How can I fix unequal motor strength on my Codrone. I have tried resetting the drone by holding the side button for 5 seconds to let it calibrate already. I have two other drones and don't ever experience this problem. Thanks!

Perfect! Works great now! Thank you!

I have made sure all the motors are connected and replaced all the blades. How do I run a calibration test, and what are the results I am looking for? Here is a pic of the bottom of my drone.

I'm using the Petrone app on my phone to fly the drone, so I don't think I'm using calibration code. Also, I am using fully charged batteries. I can't provide a video at this time. I have another Codrone that operates just fine when doing all the same things. Any ideas?

Can someone please help me with this?

When my codrone takes off, it hovers for about .5 second and then drops about a foot instead of staying level. How can I fix this?

My drone does not fly as directed. It seems like one engine has more power than another, so it goes in strange directions when it is supposed to hover in place. I have tried replacing the propellers and pushing the engines back into the body of the drone for a solid connection. Please advise.

CP210x driver

1. I am not using a USB 3.0 port.
2. I'm not currently using a Mac.
3. a. I have never received any sound or notifications from my CoDrone board. b. There is no "ports" option in my Device manager (see pic in link below). c. I have already successfully installed the CP@10x driver multiple times (see pic in link below).
4. The color patterns on my board are flashing blue and pulsing yellow.

I have downloaded all the software and drivers for Arduino, but when I go to select the port to upload code, "port" is greyed out, and I cannot click on it. I have tried this on multiple computers (mac and pc) with multiple cables. Please respond ASAP for a fix. Thanks!
