I saw the Tamiya video of the KV-2 recently. In the video it does have a different main cannon sound than the KV-1. It sounds like they took the KV-1 cannon sound and lowered the pitch of it to make the KV-2 sound. The KV-2 sound is deeper and heavier. I was anticipating they would just use the same unmodified KV-1 sound, being less work on their part. Therefore, I suspect the KV-2 has a different MF unit than the KV-1. Could you tell us the number of your KV-2's MF unit (MF-xx)? If it is the same as the KV-1, then they must be altering the cannon sound some other way..

It would be nice to finally get one of these, but money is very tight for me right now, so I have no choice but to wait until I have funds available for it. Don't know when that will be.. I have the static Tamiya Porsche KT, but again no cash to get parts to RC it and selling it won't generate enough funds for a KV (or any other Tamiya RC tank), so it still just sits in its box. RC tanks have become a low priority on my landscape. It is necessity only mode for me right now..

Anyway, I'm interested in seeing how yours ends up when it is finished.
