1/8 is good but difficult to find figures and accessories in that scale. The drive trains are very reliable due to the size. Very similar to a 1/6 in handling but a bit more rugged and reliable due to slightly smaller size and weight.
I have a 1/6 Leo 2 and there is another member on here who has a 1/8 King Tiger. Welcome to the Gigantic tank club. They are more addictive than the 1/16s.
