Electric RC cars have the advantage over nitro ones that they are easier to use. You don't need to worry about tuning your engine or using the correct starting technique. Just plug the battery in and away you go. They used to have the disadvantage of being slower than nitro cars but the new brushless versions are just as fast if used with a lithium polymer battery like all the ones we sell are. The price in general comes down to two factors, the size of the model (with 1:18 scale being the smallest to 1:5 scale being the largest), and whether they are brushed or brushless. With electric RC cars we recommend purchasing a spare second battery so you can be charging one while using the other.
