I get the 'clicking' sound when I use my 11T motor. It is the pinion gear trying to strip the spur.
When that happens and you check your spur, you will see the pinion being stripped. Either that or your spur has been stripped.
Or your motor mount is loose due to heat from the mount melting the plastic at the side of the chassis.
To remedy, use aluminium foil to fill the sides so that the mount does not move..and use a higher turn motor...I'm using 17T now..just need to test it to see if the gears can take this kind of abuse..
Was thinking of using my MM5700...but decided against...don't think the chassis or rather, motor mount can take it...and the gears as well..
from my experience..just to share..

My TT01 have started doing this in the last leg of our TCS. I think the meshing of the 25/55 gears is too loose. Try mounting the motor using the holes for 24T pinion. The mesh should be tighter but still loose enough for the gears to spin freely.
