Well I live in the USA so my opinion don't count for much but here off road is cheaper as onroad is more battery and motor or he who has the most $ wins. Off road requires more talent and less $. The cars are cheaper they don;t come out with a new modle every 6 months. Electric is also cheaper than Nitro (gas).
I know I don't belong here but I like to keep up with the RC world.
I apolagise if I have Offended any one.
