Followup:

The SH .28 motor smoked the one-way bearing at the 3rd break-in tank. It's still in a box in my closet now. I also closeted the Wolverine and devoted everything to the Savvy. It now has GPM TVPs, GPM arms, hardened bones/shafts, hardened gears, spur/bell, HPI DirtHawgs, GPM bulkheads, hi-torque servos, and get this.... wait for it... an Axial .32 that ripped the reverse gears out of it before I could say "ouch". End result. Love the Savvy and love the new motor. And I didn't have to wait two weeks for a shipment from Hong Kong. WooHoo! Ready for unlimited MT racing in spring 2007.
