I'll answer a different question. The major cost of airplanes is engine wear. Engines have a TBO of maybe 2000 hours, which means about a year's worth of flying at 40 hours per week. For a cheap plane like a basic Cessna, the overhaul is the cost of the aircraft.

If electric planes are lower-maintenance, for GA purposes, they could be a lot cheaper. The hobby would go from millionaires to ordinary folks.

Electric motors don't wear out like combustion ones do.
