Thanks for that comprehensive list of information Ron. Unfortunately there is just to much information overload for me to take advantage of much of it.
A Power 110 drive claims to be the equivalent of a 1.1 cc nitro and if that is in the ballpark than I should be ok using it to replace the OS91/4. Once I can take it to the field, the wattmeter will have to tell me if the conclusions reached with eCalc will get me off the ground with the eCalc calculated prop. From what I've read the electric drive will give me more power at the slower take off speed than the nitro does and right now that's what my biggest concern is.
I'll also need to be concerned about cooling when flying off the water; Not sure how to prevent water from getting into the components when providing big openings for cooling.
