No, that equals an 8.0 FDR. What I am running on mine is a 3.89 FDR for 17.5. There are others that go even lower and others that like it a little safer (higher) Your expereience may vary, but that is way off man. I have a 72/37 48P on mine. Track temp was over 145 degrees yesterday with air temp over 100 here. I have a fan on my ESC, but not my motor, and it came off the track at 164 degrees for comparisons sake.
