I used to run the sidewinder. its the best I had found.
before that I ran byrons and I thought it was good, that was until I found the sidewinder. I ran traxxas for a while also but I didnt really like it. it was alright but not as good as the other two.
only fuel I have used that I hated was blue lighting. its terrible. ended up just using the last quart of it as a cleainig solution.
