Yeah, there is another Sparrow owner reporting 138 watts/mile, and he does 
some cruising at 70mph going to work!

So do I.  I fixed the brakes so they don't drag anymore, and on a smooth

think there is much drag left in the wheels.
I'm wondering if I should pull the motor cover and check my brushes.
