Has anyone else had problems with the gearboxes being tight and locking up. One of ours hits a load of tension at a certain point during each rotation. On high power, it runs slightly slower than the other side and on low power, it actually stops turning at that point, as if we were sending pulses to the motor, rather than a constant signal. We opened it up to find a small amount of gear dust inside. We've since packed it with lithium grease and it seems to run fine, but it does get quite warm, very quickly.

The other one has a very minute form of this problem. If you put it on low power, you can feel the tension point very slightly, but it doesn't pose any real problem.

Has anyone else encountered this and is there anything worth telling us?
