Electric: Most electric RC cars are waterproof* - just double check in the description of the RC car you're
looking at.
Fuel powered: As all fuel powered engines need air to operate there's no truly 'waterproof' fuel powered RC
cars, however, there's some that have waterproof electronics which essentially makes the car 'splash proof' - never
submerge a fuel powered RC car.
*Note: if you drive in water (especially salt water) make sure you clean it thouroughly. Driving in wet
conditions will increase the wear and tear on components such as bearings, tyres (they can fill up with water and
overload your electrics and damage the foam inserts) and various metal parts. Even if your car's electronics are
waterproof, it's best to stay away from water.
