For EF-1 racing, the motor, prop, and battery are all specified in the rules. For sport flying or all-out speed runs, the sky's the limit -- or maybe the strength of the balsa and plywood is the limit.

The Sundowner 36 is set up to take the Power 32, but I wonder if the increased weight of the motor and extra Lipo cells would be worth the effort. The lower kV of the 32 would require a larger prop or more cells than the 1250 kV Power 25. I think you could get an 11" prop to work OK with the stock ground clearance so that shouldn't be a problem. I guess we will just have to wait till some users begin to explore the "outer limits" of the airframe's capabilities to see if the 32 would actually be better.
