Sounds like my home track....

The R2 is definitely your best bet for all around power. If you want a tad more top end, look at an OS2060, or Losi RE10. I've run the 2060, and it does give slightly more top end, but the motor hits with a little less "oomph".

The RE10 was awesome in my OS Speed...even more top end than the 2060. Considering that the 2060 had the same effect on my OD as my OS, I'm assuming the same would be said for the RE10.
