I just got this email from Castle concerning my MMM, I just thought I would share with everyone else:
[I]"This is a status update for your Mamba Monster ESC currently in for repair at Castle Creations. We have found that a small number of setups are damaging the controller, and our Engineering department is working 100% on resolving this issue. Progress is being made, and as soon as we get the ok from engineering we will begin repairing and replacing all of the Monsters that we have in for repairs.

We apologize for the inconvenience, and will continue to keep you informed.


Sincerely,

The Castle Team"
