I apologize in advance if this post comes across as accusatory, but this issue does have to be raised.

It should be noted that no attempt is made to fix any motor that fails testing - failures are removed from product inventory and isolated where they can not be accidentally mixed in with tested product. It would appear from posts in this thread that we may need to review parts of this process.

However low the manufacturing defect rate is (and given Banebots' role as a dedicated FIRST supplier, there is no doubt that their testing is sufficiently thorough), many members have pointed out that the shipping process itself is accountable for a number of ensuing problems following product receipt.
Therefore, it is likely that the fundamental problem at hand is not persay the manufacturing process, but rather the packing process which subsequently results in inevitable damage during the shipping process. If this is indeed the case, then any further attempts to improve control quality of the manufacturing process will likely prove futile.
The other problem that has been raised occasionally in this thread is the immense lead time on gearbox orders (we personally had to wait nearly a full 2 weeks for a shipment of P60s to arrive). As one of the few dedicated and valued FIRST suppliers, there is no doubt that a backlog would be inevitable, but this is the kind of problem that the company itself should acknowledge and address of its own volition.
That being said, the 775s (notwithstanding all defect receipts) have undoubtedly been an extraordinarily useful resource for those fortunate teams that have had success using them (as these teams have attested), to say nothing of the outstanding support for usage of the RS-550s (which, having had personal experience with, I can safely say were the only part of our robot that we never had problems with, for which I am eternally grateful). It is my hope that Banebots will remain a FIRST supplier and continue to support it and all the teams.
