Nitro is so much cheaper to race than electric,I'm thinking your forgetting a few things,When I was racing mod truck I remember changing alot of brushes and cutting the coms quite often,and I also had more than one or two mod motors.I also remember that they are just as proud of 1/10th scale parts as they are of 1/8th scale parts(they both cost $$$)I tend to not break as often in 1/8th also.For some I guess nitro can be more money but for me it's less.I have more money in my TC's than I do in my 1/8th scale..
