Actually, this is not a Hobby... per say. It's a combination of RCing, electronics and model building. So other than the RC Tank Forums there isn't going to be a lot on the Internet about them.
And, not to pit one brand against another but anytime you acquire an RTR (ready to run) there is going to be a lower expectation than if it were built from the ground up. Most of the seasoned tankers here take an RTR and it's way above what it started out as.
It's a fun thing to get into as we have all levels of accomplishment here so whether you run it box-stock or go full blown into modifying or customizing it, there's always a place here for you.
