I have a codrone pro and remote that won't pair. This one was used in a class and we ran into the problem of pairing too many at the same time. I believe the remote was paired with another drone. I found several old posts about this issue but I could not find a solution that DID NOT involve downloading new Arduino code to the remote. Is there a way to factory reset the remote so it will search for the nearest drone again? I am trying to get it connected and currently no other drones are in the area.

Thank you. I will try the items suggested and let you know of the results.

two of my students are not able to get there drones to work properly. The drones drift rapidly. I check all the motors and propellers. I also tried calibrating repeatably, but still no change.

Any suggestions? It seems to have been this way since we first built the remotes and powered them on.
