How do you know if its time to change the motor

[pixigraphy]

I just had a vortex ring state crash, I was wondering how do you know when its time to change the motor. Out of the four props, I tore one of them and had to change it, now the motor holding that particular prop feels different compared to the other three, this one is stiffer/tighter, less smooth, than the others. It still flies alright, but I dont want it to fail mid air. Thanks.

Cheers

I would try a new motor bearing first.

Changing your bearings is a good start but that can be challenging sometimes. Check YouTube for a "How to Video". Good Luck!

I use the App above to check and BALANCE all my motors and it works great.

Two great videos!! You can also take off your props and put your copter on a smooth table, turn her own and give it full throttle. If she starts to slide off the table then one or more of your motors needs balancing. In the past, I've replaced the bearings and that has solved the issue but when I'm feeling lazing, I just replace the motor if it's just the stock motor since they are rather inexpensive. Good Luck!
