Hi..
I recently bought a crazyflie and now I see that 2 motors work less than the 2 others. When I tried to rotating them manually I can feel that they don t turn as well as the 2 others, they seems to have more friction and the result is that they start a bit after and need more power than the 2 others.
Is that someone has already had the same problem ?
Is there any way to fix it ?
Maybe lubricate it ? but with which product ?
thanks
motor resistance/friction
Re: motor resistance/friction
Can you find the source of the problem? Is the propeller pressed down to much? Does the little bearing beneath the propeller look de-pressed?

I just broke this motor yesterday evening and when I removed it I understood what's happened
here's a picture of my broken motor

as you can see the crazyflies arms break the motor. When the crazyflie fall down and get a shock the arms create a bump on the motor and more the crazyflie got shocks more deeper is the bump until the motor is broken.
In fact this is not a problem of lubricant or whatever, but just a problem of shocks.
Maybe the motor mount should have a little plastic part to protect the motor from arms or something that just avoid the contact of the arm with the motor ??
(sorry for my english..)

Re: motor resistance/friction
Your English seem perfectly fine, I can understand you well 
It is a known problem which unfortunately isn't easy to fix, see [url*=http://forum.bitcraze.se/viewtopic.php? ... ount#p2184]this [/url]thread. But there are workarounds, e.g. to add soft landing gears or to put a bit of cut rubber band, or similar, between the arm and the motor.
