It looks like you are in a helluva place. Your new and in order to know first hand how it works you shoud go with a kit. But RTRs are factory built so they will be put together without error. Both a kit and an RTR allow you to upgrade to better parts, which will improve the stength and durablitity. Maintainence doesnt really depend on kit or RTR, more on the vehicle model; however if YOU put it together you know where everything is. And for 300 bucks you can get a great kit or an RTR. Personally, I started with an RTR and I have no regrets. The choice is yours.
