Why not at least deduct from the batteries' weight the 30-pound weight of the maximum 5 gallons of gasoline? An ultralight has to carry that extra thirty pound

Why not at least deduct from the batteries' weight the 30-pound weight of the maximum 5 gallons of gasoline? An ultralight has to carry that extra thirty pounds on takeoff, which is probably the point where the higher stall speed matters the most for safety; it seems reasonable to allow at least that much deduction for batteries. Even that would be an encouragement.
- slownews45 5y agoNot disagreeing. In my view the reliability / noise (ground issue) / pollution etc make an electric sustainer absolutely fantastic. Sailplanes can slow way down as well, so yes, if they crash its a problem, but these are not GENERALLY stall/spin into ground at high speed. Stall speeds can be down in 40kt range or lower. I don't follow this area closely though so have NO IDEA of US regulatory rules here. But the electric use cases in this general category seem somewhat clear?
