Today we will be installing upgrades on the xiaomi chimney here. We’Ll be installing the 180 motors sponsored by wblc24 and the metal driveshaft. The tools you’ll need for this upgrade is the hex key set, which you’ll need the 0.9 1.3 1.5 and 2.0 hex key well let’s start working on it now: Music, Music. After removing the power shell, we will need to remove the motor gearbox and drive shaft from the chassis. We will start by removing the plate. Here then remove these three screws to unmount the gearbox Music. Then you need to remove this wire holder here. There are three screws one two and three now you can unplug the bottle and pull it out. Next, we remove the driveshaft from the axle. If we compare the 180 model to the stock motor, you can see that it’s bigger and have a way longer shaft here. So we have to cut a shaft to a more suitable length Music. So this is how the 180 motor shaft should look like after cutting it. It has just enough space to fit in the metal, driveshaft Music. So now let’s fix our driveshaft to the gearbox Music don’t forget to install the shaft also to the axles Music. Finally, we can install our motor but it’s quite big and it won’t fit so we have to detach the receiver first put the motor in and then only we put the receiver back on top of the motor.
