60 is way high, like as in not a chance in hell high. 50s are even a bit optimistic, but with the right gearing, going downhill with a tailwind................still doubtful. To answer your question though, in the 40s is where you'll be with a Axial .28/3spd combo-mid to high 40s is where most nitro Savages hit the wall due to weight and a lack of aerodynamics. There are some Savages that are exceptions to common convention that can seriously haul ass, but not many will fall into that category.[8D]
