OMG!
To high Gov gain mixed with imperfect gear mesh I'd think.
The Helical 14t will equal your 15t straight. H gear is 127tooth where S gear is 136.

I don't know what to make of that. Wonder if the pinion came loose on the motor? Or motor mount loose? I've only had a single tooth break out when I get the mesh too tight. But when I fly by, I can hear a tick noise giving it away. This looks like it ran like that for a time.
