I have half a dozen Xl5's if you want to try putting a brushed setup on something. I also have an 8 track player for car audio if your interested. The fancy kind with rewind even.
I used to curse the titan 12T. Poor quality, short life span. Now that it's discontinued though, they actually have some value. The local track has a slash class that requires a brushed 12T. Last time I was there, they were offering $20-30 for any you had. Guess they want to keep that class...
