I recently got hooked on SC racing and wanted to enter the class cost wise. I picked up a used DESC410r and bought the copper head system. I have enjoyed my three other viper esc and never REAL problem.
Question
I have a VTX10r in my durango 4wd. Would you guys recommend me transplant that system in the SC. I would use the copperhead system for my sons. Would I notice a difference? If so what would they be? A little more smooth to throttle response?
Don't get me wrong the copperhead system flys on my local carpet track.

Last question.
One of the systems I bought used. vtx10. There other units on startup make a startup chime. This does not. Is this a setting? I have used the progauge but can not find it. No running issues..
