Well it finally happened. But this is not the typical complaining thread like most. I got well over 40 runs out of the titans using two 7-cell 3600 sanyo packs but switched a week ago to SPC 8000mah lipos and knew that they werent going to take that abuse for too long. Gonna try the Dewalt 12v motor tomorrow with a 20 tooth pinion. its only $24.95 and there's a Dewalt service center across town with them in stock. Want to try and stay waterproof threw the rest of winter.
