Introduction
The propeller motors are a crucial component in providing power to the propellers so that the 3DR Iris Plus can fly. However, if you are experiencing any problems with one or more motors that is preventing the drone from flying (which can be diagnosed using our troubleshooting guide), you will need to replace them. This guide details how to replace one of the motor assemblies used within the 3DR Iris Plus.
