Hi, I'm completely new to this forum and quadcopters so apologies if I'm in the wrong forum or if anything I say makes me sound daft!

I brought myself a UDI 829a as a starter to see if this kind of hobby was for me, it is!

But I have now encountered a problem and haven't got a clue how to rectify.

After 3 days of issueless flying one of the propellers just stopped mid flight. I managed to bring the thing to the ground nicely though.

When I power up, the propeller doen't spin but does when tapped slightly and makes a "denitist drill" kind of sound. I thought maybe it was catching on something but this doesn't appear to be the case. I've also noticed that all 4 propellers now operate sporadically. All are not at the same speed and say for instance 25% power is applied 2 might start up at 25% but one will be very jumpy and so on.

Whats wrong, please help?!
 
I would imagine its a bearing gone on motor but shows up at the high speed the motor produces possibly and thats why you cant find it by hand either that or there is grit in it
