i have been running Team Orion 19T SV2 BB 19X2 on the same tamiya ESC, no problem whatsoever, I'd say use it and keep running till it burn out, I've been trying to kill mine(looking for excuses to get new ESC

) by running 3 battery packs (IB4200) non-stop for almost 1 1/2hr, did it couple times with no success, damn thing just keep going and going and going. Maybe me and my brother should take turn to run 4 to 5 battery packs non stop next time and see if we can cook it.
