Thanks GWH,

Yea, we're stuck with this setup, looking for a way to make it workable. We took the dealer's recommendation, blindly thinking they knew how to set up. The motor has the power to do the job, it's just a propeller selection challenge. To get 1100 Watts out of this thing, we'll have to swing a BIG prop, probably 18-20 inch diameter. [X(]

But, since it has been set up and run, they won't take it back or exchange it, and battery was custom. I should have done calc's on it to see if they spec'ed it right, I didn't. I should have insisted on gang-wiring standard cell packs, I didn't. Shame on me. [:@]
