The Backwash Pro is the ultimate nitro radio controlled car with many hop ups included as standard. If you want a race ready model with all the main upgrades pre-installed then this is the perfect choice. You can't get a 1/10th buggy with a longer features list or that looks this good. This version takes a standard Backwash and then crammed it with all the best optional parts which if purchased separately would cost a lot more. Also included is a rechargeable battery pack and charger for the electronics which gives more power and speed to the servos than using normal AA batteries.As well as all the features found on the standard Backwash nitro radio controlled car, this pro version includes an arsenal of aluminum upgrades, including comes suspension arm sets, upper chassis, front and rear servo links and pro shock absorbers
