RE: 1/16 E-100
The E-100 is MUCH larger than a king tiger. The PROTOTYPE had a modified King Tiger motor installed but production ones were to have a more powerful motor installed. For me its the fact it was ALMOST completed that makes me want to build one. To see what one would have looked like moving on the field among other tanks of the time.
There is a 1/6 Maus out there. It looks aewsome.
