Does this seem high to anyone else? I run the Tekin 5.5T SC4x, which is 4000kv as well....and I know this isn't entirely comparing apples to apples, but I can get damn near 15 minutes out of my Reedy 5500s.... 5000mAh in 6 minutes is more than double my power consumption....

The main reason I point this out is that if there is some drag somewhere in jsamarin's drive train, that could explain both the high level of power consumption, and the exploding idler gears.... If it's the rear idler, I'd be looking for drag between the idler, diff, rear CVDs, and rear hubs.
