Bashing or backyard bashing is the operation of a radio controlled model in a casual, non-competitive environment outside of organized racing.
Non-racing model cars and trucks such as the Tamiya Blackfoot were among the earliest radio controlled vehicles available. Models of this type remain popular today. Some are slightly detuned racers such as onroad sedans by Team Losi and Team Associated while some nitro-powered monster trucks such as the Traxxas Revo and HPI Savage 25 are specifically geared toward "fun running."
The burgeoning ready-to-fly R/C aircraft market has not only introduced new pilots to the hobby who would not have otherwise joined it due to the building involved, but have opened up an entirely new bashing category. Many planes in this category are geared toward first-time pilots and operate on as few as two channels.
