I have over a year on a d3.5. I was wondering if I should replace it with a newer motor.
As of today, the Trinity D3.5 10.5T, 13.5T, and 17.5T are no longer ROAR Legal motors, so if you plan on running ROAR events, I would suggest replacing it.
As far as it being old, it all depends on the abuse it has endured. Multiple classes, or every weekend is abusive regardless of temperature. Think of it like a car motor, the more miles the weaker it gets.
I have a friend whose D3.5 now has brown wires from being at 160*-200* on many occasions, it still runs great but it does fade substantially into a run.
