4200XL gearbox failure out of the box?

[TheBennyB]

Yea I already tinned and got the jumper in place. 2nd planetary is even worse. I only counted one existing tooth on the final gear. Hope to get some replacements once I hear back from Tang and RC4WD. Would love to know what happen to these. Wonder if it was the 8 year old's first day on the job that does the "tested before shipping." Moved it a foot heard some crunching and said yup....good to go. If nothing else it's provided me some laughs and a crash course on how this clone goes together.
