RE: Motors to replace the EV Warriors [TANKS]

[himself-at-adamwells.net]

Hmmmm... I suppose having a motor catch fire and burn the tank down could be a 
slight problem. On the other hand, it could be an added touch of realism for a 
Russian MBT... 

I guess a good cooling system will be needed. I seem to recall reading that 
Makita motors in the Hetzer have built-in cooling fans. With the DeWalts 
similiar fans will have to be added.
