It all depends on your point of view and preference. I personally prefer nitro over electric since an electric vehicle just doesn't have that excitement factor to me. I do have electric vehicles and although I enjoy them, I have always liked nitro more. A brushless motor does not have an armature or brushes to transfer the power from the ESC to the motor, so there is nothing to wear out in a brushless motor except maybe the bearings. Google "brushless motors" and your search results will explain the differences. 1/8th scale is larger than 1/10th scale, just like the fraction indicates. A full size car is 1:1 scale a 1/10th scale is roughly 1/10th the size of a full sized car in length and height. 1/8th scale cars/trucks can be mighty expensive, but are usually more durable than their 1/10th counterparts. 1/8th scale cars are like the "luxury" vehicles of RC.
