I ran it a couple more times in the street and around the yard, and the pinion seems to be holding up just fine so far.

Yes, I run 4s with the 2.5d. Speeds a really too fast for the small track I run at but it still has plenty of torque.

BTW: that 16.8v figure doesn't last very long. If I let the packs sit for an hour or so after a charge, the drifts back down a bit even with no load. So, I would assume that the voltage drops to ~3.7 within a few minutes of running so that rpm isn't being hit very much.
