I just got the following email:

This is a status update for the repair of your Mamba Monster ESC. We
believe that we have isolated the issues causing some of these units to
fail and have found solutions for them. We are now in the process of
acquiring the raw materials we need for the next production run.
Repairs will be the first units to ship out as soon as the next
production batch of Mamba Monster ESCs is complete. At this point we do
not have an accurate time table, but as soon as one is available, we
will send another e-mail update with an estimated ship date.

Again, we apologize for this inconvenience and want to let you know we
are trying to get your repair shipped out as soon as possible. We will
send another update soon to keep you up to date.


Sincerely,

Castle Creations, INC.
