Sorry, I should have been more clear - I meant the maintinence would be inexpensive compared to a gasoline piston helicopter. Given the requirement for safety in aviation, piston engines have to be inspected (and rebuilt, at a cost of ~$50k) every ~2000 hours the aircraft is flown. This cost essentially goes away with an electric engine, partially because they last 10x as long, and partially because they cost significantly less than a piston engine. |
