Team Losi XXXS problem - very high pitch noise
I have a Team Losi XXXS. It's been running with no problem the last or so, even though I only used it less than 10 times during the last year.
The last few weeks however, I have been racing it with a few friends in a track that we built in a parking lot.
Last week, it started to put out a very high pitch noise after running for a few laps. I thought it was the motor that is having the problem, but the problem is still there after I replaced the motor. I also adjusted the motor position, thinking that it may be the motor gear that is squeezed too closed to the spur gear.
but that's not it either. I have never taken this car apart before, so I am not that familiar with the single belt system. what's worse is that some of the screws seem to be stripped out because they keep slipping when i tried to open them with the 1.5 mm wrench.
Is this noise a symptom that the belt needs to be replaced?
i took the cover of the belt mechanism from the bottom of the car and everything looks ok, meaning there is no dirt or stuff getting stuck. I sprayed the belt area with air compressor to clean up any dirt that may have caused the problem.
anyone out there had similar experience with this car?
