Good point. I hadn't considered IC vs electric. Electric power (I think) would be much more linear across the rpm range.
Due to space and weight concerns, I'd really like to stay with 6s batteries. AUW is likely to be 18lbs.
I calculated watts using 22.0 volts. Even at 22v and 1100w x 2 = 2200w, I get 122watts/lb.
Using your info above, is peak voltage for a 6s battery 25.2v? If so, that works out to 2520w and 140watts/lb.
Please remember... I'm still learning. Am I understanding you correctly?
