isn't half bad.
find yourself a losi RE11 pipe and it screams with this combo. I was lucky enough to find one for $30. just have to keep an eye out for one. this is what the team drivers use as they like the high end power delivery of it. it really made the huge difference over the rtr pipe I had with the motor.
I have this setup and I'm very happy with it's performance for a RTR kit engine it does very well and holds a tune with 30% very very good.
also I've bought a few things from the lumidave on ebay. he's super fast a shipping and the parts are always as he states they are.
