High cell count, when to add a receiver pack?

Thanks,

I am way overgeared I guess. I am at 16/87 with m2k's on my stampede and when running twelve cells today it got up to 300 degrees f :dft002: :dft002: :027: . The controller was 180 degrees f. I guess I am going to have to drop a few teeth on my pinion or go up to a 90 tooth spur.

10 and 12 cells is alot of fun though. Which lipo would be equal to 10 or 12 cells?

The stampede just rides wheelies all day with 10 or 12. I am thinking of putting the 8s in my rustler and putting my ss5800 in the stampede.
