I thought about the same thing.

Perhaps I wouldn't have to gear it so low with a 10XL...or a 9XL....which would make up for the lack of kV. The extra efficiency...about 10%, should yield higher run times...which is what I was going for in the first place. Hmmmm...except, running at a lower voltage knocks down the efficiency...so maybe the difference is only 5%.

I placed my order for the gears and motor last night. If I make a change it better be early this morning.
