All good points, again I think its the level you want to be in. I am sure the RTR he his talking about it good starter car. But as you get better is that car going to take you to the next level, I have not seen that car in West cost in Expert race yet. But I could be wrong. One reason I choose the car I drive was not for cost but also for support, many others were I race drive this car, helps to share setups, parts ect some times when needed. The OS motor is alot cheaper seems to be doing very well as far as performance. Its matter of Choice, and your budget. I guess on good day an RTR can have good lap, time and a win. What it matter as long as the person who owns it and drives it walks away and the end of the day and says that was fun.
Thats why we do it for fun.
