I’d hate to see a battery fire on one of these.
I think it’s too ambitious and the future of GA is in retrofit alternative fuel engines be it Diesel/JetA or soybean oil.
A run of the mill PA28 doubles its range and endurance with a JetA engine.
10hrs/1000 miles.
There might be a niche market for electric in light sport or Powered parachutes or something similar.
Maybe...
