I am looking to get a new 17.5 motor for my SC5m. I was thinking about the Trinity Monster Horsepower 17.5 Maxzilla or Team Scream 17.5. Has any used either of these motors? Is the new Trinity motor better than the D4/24K? I run on a small/medium sized indoor clay track. There is medium high/high traction. I want to buy a stronger motor than my Tekin Gen3.
