Yeah, plus the cost for a new battery after probably less than 1,000
recharges. Plus motor cost. Plus plus plus... And your hamburger will
ge cold when you arrive - if not even the restaurant has closed since

Take a small piston engine instead and get better performance at
similar or even lower total cost.
