Well today, I spent the entire day trying to get my buggy fixed at the hobby shop. Come to find out, my one way bearing or something like that got screwed up i guess because of the roto start. My car engine would not even try to turn over. I bought a starter box, and the car fires right up. My question is, which is more popular, and which is more popular at the tracks? The Box seems so irratating to have to carry around, and it doesnt always seem as easy to start as the roto start. On the other hand, I dont want to run into the problem I had today that made me buy a starter box. Now, if I continue to use the starter box, what is the best way to get power to it? Keep using the (2) 7.2 batteries that are required, or is there a more popular way to keep it powered at the track? Ive only been to a track once.
