I also bought a Silver Arrow V2.0 5.5R that I'm keeping for my SC10 4x4. I originally purchased the items direct from SP USA for my SC truck but realized that the battery I also purchased (from HobbyPartz) was way too big for the SC10. The ESC runs better with 3-4 cell lipo packs compared to 2 cells. Thus the reason why I purchased the 3 cell lipo hardcase.

You can purchase other motors from the SP USA website:
