Ran my D4 17.5 today in Blinky. Asphalt track 100' x 60'. Track temp was 143°(almost 60° C). Ran 55° on motor, stock rotor & geared 3.8. It ran great. Pulled hard & temps was 170°+. It got to 181° in the main. Pushed it real hard. Lots of D3.5's in our main. They pulled about 20+ feet longer then my D4. It had more to end then their cars.
We have our Electric onroad series (EOS) next Sunday. I will see how it runs against our other fast racers in our state.
