Einleitung

The DC motors which power the propellers are relatively easy to break. Fortunately, they are also relatively easy to replace.

Be careful to avoid pulling off the board-mounted connector, as shown in the third photo. If the connector starts to come loose, just press it back down and it will snap into place.
