Hi:

Last week I bought a 645MG for my Wheely King (axle mounted) because I was worried about the stock servo being too week.
My surprise was that the 645MG lasted two batteries (the stock servo is still working after 20+ batteries).

When I checked it I realized that the last gear was completely striped.

Am I wrong or this servo should be ok for a Wheely King???

What could have happened?

thanks!!
