Traxxas fuel is decent fuel but it's very oily which turns a lot of people off becaue the extra oil gets all over your starter bearing(one way bearing) and will make it slip and not start. Also the extra oil comes out of your exhaust and then attracts mud and dirt making more of a mess. I run Byrons 20% with 12% oil content and it works very well in all of my nitro rigs. If you buy fuel online then they'll charge you a hazmat fee and adds about 5 to 8 bucks a gallon in costs. Before you purchase any rc you should go to your local hobby shop and see what they carry. If you need parts and you will, you can buy them and be up and running in no time. Also if you have any problems they'll be more than happy to help you. If you buy online and then have a problem and you bring it to them to fix, then it's like bringing your own steak to a restaurant and asking them to cook it for you for free. After you get your feet wet with a nitro and you're ready for another one(like we all are) then you can buy online and go from there.
