sorry but tamiya is not a very good rc to use all the time. they are "model kits". most people build models and put them on a shelf NOT drive them every weekend and beat on them.
tamiya offroad cars will not hold up to daily use period.
yes they are great at making "scale kits" but no true offroad durability.
when was the last time you saw someone running a tamiya offroad and it holding up to the abuse?.
i'm tired of people *****ing about wanting a kit. either buy whats out on the market or buy a rtr and tear it down and build it yourself.
crying about it here or any forum will get you nowhere.
