All of the Nitro racers mentioned and more certainly deserved to be recognized. And there are more. To name one absolute best is really impossible considering that racers all have different situations in their lives and their racing environment.
That said, it's great to see the different names listed of current and past great racers, so don't stop adding to the list.
And I will add one.
Gus Johnson!
During his time he was a dominate force in the 1/8 Scale and Sport 40 classes. Gus designed and built his own boats.
